Mystery of F-22 illnesses grows

By Larry Shaughnessy

Even as the Air Force searches for the reason pilots are getting sick flying the F-22, a new mystery about the troubled stealth fighter jet has come to light: Why are mechanics on the ground getting sick in the plane as well?

The Air Force has been looking into a number of reports that pilots experienced "hypoxia-like symptoms" aboard F-22s since April 2008. Hypoxia is oxygen deficiency.

The Air Force reports 25 cases of such systems, including 11 since September, when the service cleared the F-22 fleet to return to flight after a four-month grounding.

The fleet was grounded in May 2011 so the service could check the hypoxia reports, but the order was lifted in September under a "return to fly" plan, with equipment modifications and new rules including daily inspections of the life-support systems.

"Early on in the return to fly we had five maintainers that reported hypoxia symptoms," Gen. Daniel Wyman, command surgeon for the Air Combat Command, said during a conference call with reporters Wednesday.

The maintainers are mechanics on the F-22's ground crews who sometimes have to be in the cockpit while the jet's engine is doing a ground run.

"The maintainers, when they are doing their ground run, are not on the mask, they are in the cockpit," Wyman said.

The problem with maintainers getting sick while on the ground throws a wrench into some of the theories about why at least 25 pilots have suffered hypoxia symptoms.

The Air Force experts trying to figure out the cause of the problem have pointed out that the F-22 flies higher and faster than its predecessors, the F-15 and F-16.

There has also been speculation that there perhaps could be a problem with the system that feeds oxygen to the pilot's mask while in flight.

Asked what is causing the symptoms in maintainers on the ground, not wearing a mask, Wyman said, "I can't answer that at this time."

Sunday, two F-22 pilots told CBS's "60 Minutes" that they would not fly the jet any more. One of the reasons they gave was that there is a problem with the carbon filter built into their mask to help remove contaminants from the air they breathe.

Wyman said that "a black dust was noted in some of the breathing hoses near the filters. We analyzed this dust and found it to be activated carbon."

But no activated carbon was found in "30 pilots who had their throat swabbed for testing."

Activated carbon is an inert form of charcoal that has been used in air filters for years.

Nonetheless, the Air Force has decided to remove carbon filters from the F-22 pilot masks.

The Air Force said Tuesday that no disciplinary action will be taken against the pilots for taking their concerns to "60 Minutes."

    Works For Me After destroying my rputtaeion and becoming pretty much unemployable because of falling asleep several times each afternoon I started taking dextroamphetamine sulfate. I started with 20 mg (2 X 10mg spansule) in the morning and ramped up pretty quickly to about 50 mg/day. Currently I take 3 X 10mg spansules when I awake in the morning and then either 5mg or 10mg (quick release) at 10AM and 2PM. I stay awake and alert. I've been at this level for over six months and unlike my initial fears I don't seem to be developing a tolerance. I used to lay in bed for 8- to 10- hours each night, waking at least once an hour. Now I only sleep about 5 hours/night, but it is deep sleep.GD Star Ratingloading...

    Must be the Windex they use to clean the canopy. Amonia is reacting with the polymers and emit toxic fumes. They should switch to plain water and a squeegie.

      The canopy is cleaned with plastic polish,non-scatching..Everybody uses it. No problems except wiiping the streaksout. The only thing I can think of ,is the pressurization system.Ground crews who run up engines in the cockpit with the canopy closed would be exposed.Also, a thought, Labyraith seals used in the engine are generally made of some carbon material,seals the engine bleed air internally.Is these seals made from carbon or are made of different materials and/or leaks bleed air into the cocpit.If ground crews use the mask on run -up,I can see why they are looking at the mask. If not ,try pressurization.. ?

    The AF has been covering all their bases, if slowly. After looking at all the available reports, I am increasingly thinking this is more probably an issue of a sort of group hysteria meme. By hysteria, I do not mean that in a derogatory sense, because the stresses on these pilots while in flight is extreme and issues with common inertia-related breathing strain and vertigo in combination could cause symptoms that they could be easily motivated to over-judge as hypoxia. The new carbon filters shedding into the breathing loop probably made the situation more claustrophobic and stressful, not to mention worrisome about something possibly more serious when they began coughing up carbon gunk.

    But the original incident in Alaska was apparently not a malfunction of the oxygen generation system. There was a failure (or perceived failure by the automated BIT/failure addressing systems) of one of the engine's bleed airs. That bleed air obviously has to be shut off if that is the conclusion the computers make to save the engine from exploding and was shut off, resulting in the oxygen generation system being inoperable. When the pilot realized he should compensate for this by turning on the emergency oxygen, he had to twist around in the cockpit to get to it without bumping the bulky nightvision goggles he was wearing into the canopy. That contortion of his body allowed the pedals and the stick to get nudged just enough (the stick is particularly difficult to judge how much input is being applied without looking at a heads-up display or external visual reference since it is a pressure/force stick that doesn't move much), and he accidentally dove the aircraft into the ground.

    Now, yes, the handle he was reaching for was difficult to find and could not be grabbed easily by feel alone due also to its shape. The AF is finally addressing that issue. The other cause is just as serious: the F-22 cockpit was never really optimized to be flown in wearing bulky nightvision goggles added to the helmet. And the size and shape of that cockpit was the result of massive research. The anthropometrics were originally designed with a VR display built into the helmet that would project cueing information, flight data, and light amplification or thermal augmentation in front of your vision at all times (the latter from the IRST). The funding for implementing this essential and originally-intended feature has been cut by Congress & the DoD and continually moved back to later and later dates. The full helmet mounted display would have done two things: 1) it would have been less bulky and un-ergonomic, making it easy to turn in the cockpit without bumping your head gear into anything during night flights, and 2) it would have made the aircraft's orientation obvious to the pilot as the positional symbology information would have been in his view at all times like a floating HUD in his vision.

    The idea that some F-15, F-16, and F-18s are already getting the first generation JHMCS, not to mention the F-35 is being completely built around an even more advanced version, but the F-22, the most advanced manned air-combat fighter that will probably ever be built, is the victim of these sorts of penning-pinching budget cuts, should give everyone pause. The F-22's helmet cueing funds have been cut. Its ground and side radar implementations have been reduced, cut, or moved to “a later administration”. The Infrared Search and Track (IRST) system budget has been cut. The Datalink modernization (so that it can integrate into the rest of the newest AF feeds) has been cut. The implementation of the newest GPS munitions cannot go forward with these cuts. And yet people keep complaining that the F-22 can't be used in Afghanistan and that it's been more difficult to deal with some of its limitations than expected. These are budget-connected limitations imposed by the rest of the government on the F-22 fleet. At this point, the program appears to have been short changed by Congress, the Defense Department, and the media.

      While the description of the incident itself (and the politics behind it) is certainly plausible, the "mass hysteria" thing is a stretch. That is often used as an explanation for situations like this, but is just as often proved wrong.

      From the initial claim that hypoxia was a symptom of oxygen deprivation pretty well made it certain that CNN's expert is incompetent. Now the pressurization issue has pretty well been discredited, with the geound crews getting sick. Is there carbon fibre delamination?

        "Hypoxia-like symptoms" was the term used. And, as the article said, "Hypoxia is oxygen deficiency." No one (in the article) said that the symptoms were CAUSED by oxygen deficiency, merely that the symptoms RESEMBLED those of oxygen deficiency. I don't see any evidence of "incompetence" - at least not in the article (though maybe in some of the comments above).

        Your theory is valid. Lamination of anything requires toxic resins and hardeners. We sometimes see laminated products "popping off", a term for "still curing and hardening" up to a year after production of our products.

        As the Nyquist shaking of this final airframe type was never done, any delamination could be of a far more serious concern. The Frequency domain response of the airframe has been unknown since the interation of stiffening the tail boom pre airframe 28 (27 scraped airframes) also has the stiffened tail (titanium spar), to pervent cracks; induced by the stiffened tail boom.

      I can be very difficult to isolate a chemical that may be in the air (or perhaps absorbed by touch) in the PPM or PPB range of dilution. You kind of have to know what chemical to look for, and they've no doubt eliminated most of the obvious ones.

    Each F-22 requires "1,000 subcontractors and suppliers and 95,000 workers" to build." How many ways can you spell "Stupid"? For an aircraft that was unveiled in 1997... we ain;t doing so good. Time to scrap it. Might as well pull the plug on the obscenely expensive F-35 too. Ask me, the Tigershark people had the right idea years ago. Build it right, build it fast, built it for a purpose... stop building "all purpose" "flying pianos".

        The Chinese parts are a direct consequence of the F-22 program failing to comply with MIL-COTS. (ie mil-hdbk-217f) The junk yard was the only way to comply with the contracts, as the F-22 is on the dead side of a production break.

      Very true..formaldehyde gas comes off new Silicon rubber parts, or seals...

      But that carbon could be breaking down off the filters because of some other gas effecting the filters..and the epoxies used could be breaking down due to hydraulic fluid leaks, or oils, cleaners, or jet fuel on the composites, or just heat on the composite surfaces, or the sun's ultra violet rays at high altitudes, effecting the epoxies...all of these concerns were brought up with design of Boeing's new Dreamliner 787 passenger jet...the fact these are recent problems, after the planes have been flying for awhile..just point to a possible breakdown of the composites after time and exposure to the other chemicals used in the plane..

    Like the last poster said its some sort of nitrogen leak within the planes fuselage. Most likely part of the fuel tank venting system is defective or improperly designed and is letting the plane fill up with nitrogen which is displacing the oxygen throughout the interior of the plane. I'm not familiar with this plane but I know that every other fuel system I deal with utilizes carbon cannisters as part of the fuel system, the traces of activated carbon would seem to be the smoking gun.

    This probably is the problem --nitrogen displaces o2-–from (The F-22 features eight internal fuel tanks, and there is a boom-refueling socket in the middle of the back. The internal fuel tanks are normally flooded with nitrogen to reduce the danger of fire from fuel fumes. The nitrogen is derived from the atmosphere by an on-board nitrogen generation system. The F-22 also includes a fire-fighting capability, consisting of infrared and ultraviolet sensors linked to a Halon 1301 fire extinguishing system. While Halon is an ozone-attacking freon, designers are searching for "green" alternatives, and the fire extinguishing system was designed to allow the storage of alternative agents with up to 2.5 times the volume of Halon)

    Hypoxia has to do with pressurization, not oxygen. When the partial pressure of the nitrogen in blood drops it comes out of solution. The F-22 is a disaster.

    The masks arent used on the ground,usually. I would look at the pressurization system.That's the only thing they have in common. Check the filters closely. Pressurization is indirectly supplied by engine bleed air.Check bleed air seals.Sometimes the smell of lubricant seeps through the system.When you run up an engine,you close the canopy ,especially if it's cold outside.That's why the run up crews are experiencing the same symptoms.Has nothing to do with the mask.

      That $400 million figure is inflated. It should be in the high $300 millions and it is not the cost of one aircraft. It is Total Ownership Cost, the cost to buy the airplane and own it for 30 years. It includes all the fuel the plane will ever use, all the spare parts and consummables, periodic overhauls, flight and ground crew wages and allowance, travel and training, new facilities and all the support equipment necessary.
      The "Flyaway" cost of a single F-22 ready to use is $150 million. For comparison sake, the most recent purchases of F-15's by Singapore and South Korea had a flyaway cost of around $110 million per plane, and this is for a forty year old design with a modern radar, fire control and countermeasures, but absolutely no low observable treatments.
      Some segments of the press will use the Total Ownership Cost figure to make aircraft appear to be more expensive than they are. It is not a dishonest number, but it is used dishonestly in arguments.

        The first 120 F-22 cost $500,000,000 each and the next 47 cost 387,000,000 each. The F-22 is made entirely of obsolete electronocs and will never go to war.

        Cheese, you are correct. The $300M number is a very inclusive number and accounts for everything from research, development, testing, support equipment, spares and, I don't think you mentioned it, related facilites construction costs. Fly-away is actually closer to $140M than $150M. Tarver, you should research more carefully; or perhaps more to the should research before you speak. Your numbers are very wrong.

        The cost was $60 billion for the first 120 and 387 million for each additional copy. Less the 27 production airfames that were incorrectly manufactured and destrouyed.

        Using total ownership cost to price a plane is a huge leap forward in containing defense expenditures, so I wouldn't call using that figure dishonest or misleading; quite the contrary. Defense contractors and the pentagon have been lying for years about the real costs of these weapon systems. Taxpayers eat the cost of the R&D; they buy the plane; and then they have to go back and buy the spare parts. Read about the C-5 and you'll understand why using total owners cost is a really good idea.

Almost everything about that airplane is classified. About the only foreign components might be the Martin Baker ejection seats, which are British. I don't know if we manufacture those here though we have a specific version for US aircraft.

    It might not be something inhaled as it might be skin contact/absorption, as it seems when reported somewhat slow acting on the pilots as they are more covered up and faster on the mechanics that are less so. Some sort of contaminate absorbed through the skin.

    I would take some sort testing of the air within the cockpit, not the oxygen system per say, but the atmosphere in general while the plane is under power, and well as not, then followed by testing of anything the pilots and mechanics both wear while in the plane, for anything that might combine and form some sort of toxin.

    I believe it is more a contact thing than the oxygen system. Blood testing of the mechanics and pilots is in order before and after each flight, or even after prolong exposure while in the closed cockpit

        . I would always hear music in my head, cmrieocmal jingles, and all the music I'd listened to in the past. Sometimes that could get very annoying. Dexedrine Spansules have worked well for me. It produces a calming effect and helps get rid of the brain chatter (music or otherwise) that used to distract me during tests or essays. It also improves my mood, not by making me happier really, just more stable. I don't get mad as easy anymore. I have tried all the meds. My favorite is definitely the dex spansules, second favorite is adderall xr(it isnt as strong as dex) Regular adderall is ok but long term it loses its effectiveness. Ritalin gave me horrible headaches. Most talk down about dexedrine spansules but you shouldn't knock it till ya try it!

    Josh, relax... The Raptor's been at IOC for 7 years now, and there have been 2 crashes, both at extreme speeds/conditions – There is a problem with the O2 system SOMEWHERE, and even though it is an insidious problem (hypoxia symptoms), it's not a sign of a failed project; just a design problem in one of its systems.
    It's obvious that because the Raptor is so expensive, people seem to believe that all risks and deisgn issues have been completely eliminated, that everything should work perfectly every time, and that if there is a problem then the whole program is a failure. Far from it! When the -35 EVENTUALLY takes to the front lines, the F-22s will be holding their hands, keeping them safe. Anyone that wants to bitch about the cost of the Raptor should consider: 20+ years ago we we had a prototype of the fighter (F-22) with better stealth, performance, speed, altitiude and air-air capabilities than the aircarft we're currently struggling with (F-35); we developed NEW technologies which the -35 supposedly would borrow from, to save risk/cost; we then slashed the F-22 build numbers to ONE-FOURTH the planned numbers; and then closed the line to hinder its further development and remove competition from the F-35, by quoting per-unit costs with all the R and D included and dividing by the reduced build number!!! That's not brilliance,that's a travesty. Put simply, let's take the 60+ F-35s that can't even drop bombs and figure out their unit cost using the same methodology applied to the Raptor. Guess what? They F-35 Unit cost is well over $500 million a piece! Add in the charges for the latest fixes, a REAL helmet, and the 12 million lines of code left to write, weapons testing, airframe mods – You SHOULD get the picture.

      Talking out your exhaust. F-35 carries two JDAMs internally for low observable missions but has conventional underwing pylons to carry more ordnance when stealth is unnecessary. It will carry air to surface missiles internally (Norway has a modified NSM that fits into the F-35 weapons bay) and all the usual ordnance underwing. Even with two JDAMs in the weapons bay it retains two internally carried AIM-9's for dogfighting.

Did you know that dislexic people can read and understand books without the effects of dislexia by reading with certain color glasses or reading in certain color lighting? Similarly, in non dislexic people, dislexia can be induced by reading in certain color light.
      I am beginning to think the color of that canopy affects a small proportion of pilots and ground crew. Just an idea.

    It is a curious problem since the other problems could be quickly diagnosed due to them cropping up in prior generations of aircraft. What I am curious about if the F-22 still uses the highly toxic paints that the F-117 did and if so what would be the symptoms of poisoning. If that was the case it would explain both pilot and ground crew exposure.

It was the medicinal equivalent of having cold water thrown on my face but without the shock and subsequent anger and the water-thrower.I now fully expect the FDA to find a stupid reason to remove this product from the market .As you can see, I'm not taking it anymore.

    I have the answer.
    People are looking too hard at the oxygen deficiency angle due to the fact that the sickness has "hypoxia-like symptoms"
    My personal opinion on this is that they will find that the problem is a "High Frequency" issue.
    At a certain speed setting, the engine is likely resonating at a high enough frequency to debilitate and sicken anyone in the cockpit during the engine operation.
    This would explain why it happens to people with and without masks and also why it doesnt affect all people the same.
    One specific frequency may sicken one person but not another.
    It will be interesting to see if i turn out to be right on this.

    Im no rocket scientist, but if the engines are on..and the maintainers were not wearing masks while experiencing symptoms then clearly the one thing that consumes oxygen on the entire airplane (the engine) is pulling air from the cockpit...even the pilots oxygen system clearly has a leak in the piping somewhere thats causing it to bleed to cabin.

    If the ground crews are getting sick – then the issue might not be the oxygen system rather an issue with the Enviromental Control System (ECS – Air Conditioning and Heating). Ground crews have no need to utilize the oxygen system while on the ground. However, with engines running – the ECS system is functional and is possibly allowing fumes from engines to back into the cockpit.

        Dexedrine (dextroamphetamine) for ADHD: I used Ritalin for many years before reizlaing it had little or no effect on me. I think the placebo effect applied not only to me, but also to my parents and teachers. Upon finding out that it's quite common for some patients to have their medication switched 2-3 times before finding one that works, I decided to try Adderall (which worked amazingly, but gave me insomnia), Concerta (which didn't work on me, since it's basically the same as Ritalin), and finally settled on Dexedrine, which I don't know how I ever lived without. Of all the ADD medications I tried, it was head and shoulders above the rest as far as effectiveness AND had the fewest side effects (which were barely noticeable and disappeared after a couple weeks).GD Star Ratingloading...

    I question the USAF "experts" quoted in this article who claim the F-22 flies higher and faster than the F-15 it replaces. That is untrue. The F-22 has stealth over the F-15. Both max speed and service ceiling advantages go to the F-15 Eagle. These are not debatable. What may be debatable is whether each F-22 is worth costing five times what each F-15 cost.

      It seems to me you're talking about the Maximum speed of a clean (and stripped-down, by the way) F-15 being somewhere around Mach 2.5 Well then, what do YOU think would happen if we stripped down an F-22 and opened its burners up??? Any idea how fast that sucker would go? I'm guessing very close to Mach 3, if the composites didn't fail. 😦
      In ANY real-world scenario, where fighters carry weapoons, the Raptor's going to be doin SUSTAINED Mach 1.5+ with a boatload of fuel, 8 AAMs and 500 rounds of 20mm, while everyone else is doing Mach 0.9 and/or suckin down gas tryin to compete – So yeah, the Raptor IS faster than the F-15 or any other 4th-gen – you just have to understand the true context and implications of its caabilities. Put simply, a fully loaded Raptor is faster than ANY loaded fighter aircraft out there, by FAR. And that's not even considering what it can do aerodynamically and targeting-wise to you at those speeds and altitudes. It's a genuine monster, even considering its cost.

      An F-22 is given the ability to fly in excess of 60,000 feet altitude with full weapons load out. A slick F-15 with absolutely nothing carried externally might get that high, but certainly not one with a nornal weapons load. Most current tactical jets take a long time and use an awful lot of fuel to get to 45,000 feet with their max payload. In practice they seldom fly that high. 35,000 feet is more common.
      Find out how hard it was for an F-15 to reach launch altitude for an ASAT launch. F-15's had to use a supersonic zoom climb just to reach 38,000 feet, by which time their speed had decayed to only Mach 0.94. The F-22 operates at far higher altitudes as a matter of routine.

    The real culprit for the problem is Senator Lott from Georgia. Lockheed-Martin is based out of Georgia, while the F-23 produced by McDonnell-Douglas was produced elsewhere. Test pilots preferred the F-23 over the F-22, and it showed better test data in flight, but since Lott was head of the Armed-Services committee, guess which company won the contract. Don't blame the AF for this one; it falls solely on Congress.

Three, while he was the Senate Majority Leader for a peiod of time, he was merely a freshman Senator when the F-22 beat out the F-23 and would have had no influence on the Air Force's decision. Four, the YF-23 was developed by Northrup, not McDonnell Douglas. Finally, Lockheed Martin is not based in Georgia but rather Bethesda, Maryland. Please try use facts in the future.

        Actually Northrop and MD were teamed on the YF-23. Just as LM and Boeing were teamed on the YF-22.

    Have there been any changes in the last year in any plastic or rubber component in the cockpit, especially ones with plasticizers? (That would include vendor changes down the line with subcontractors supplied parts). Any changes in sanitizing methods or disinfectants?

    Interesting.....of course they've checked for contaminants like carbon monoxide from engine exhaust....plasticizers from materials in the cockpit??

    Oh you idiots. The engine is too close to the cockpit. I bet at higher engine speeds there is a problem, right. And it doesn't matter if the jet is on the ground. Your sucking air from around the cockpit. You got so many design problems with the jet, give it up. I know it flys like nothing else in the sky.

      Decent! Compared to Adderall and ESPECIALLY Ritalin, Dex is less harsh overall on my body (while coinmg down) from the uplifting effects. I've only been on it for a few weeks, but Im quite familiar w/ stimulant ADD meds! Being I have Tourette Syndrome I have great difficulty focusing, compared to even an average person who just loses focus here and there. Even though any kind of stimulant (coffee, ADD meds etc..) clearly accelerate my tics to a degree , its just to what' degree can it be at least semi manageable. Ritalin was the WORST. I cannt begin to describe how harsh that med was on my body, tics, moods etc BAD news! So than I switched to Adderall. Clearly Adderall was better overall than Ritalin. The going up' phase was very effective, but coinmg down (again) was a bit difficult. It made me drained and irritable but NOT as bad as Ritalin! After finishing w/ the Adderall, I decided to go on Dex. after seeing the endless positive reviews on this site! For me, like I mentioned, my biggest issue from any ADD meds are the coinmg down' sensations more than anything (again due to my Tourette).Im seeking to minimize that crash' effect which I clearly felt from Ritalin and to a degree Adderall! So far w/ 10 mg of Dex. the ramping down phase has been okay. Not totally smooth, but much more manageable and tolerable than the other meds! The only time I had a major issue was the 1st time I took the Dex. Since than though, Ive responded okay to this. Seems my body has adjusted rapidly. The tics motor up, but they're not severe (like before). Maybe cause Im only on 10 mg I dont feel much of a rush/ uplift like I did from the Adderall, but its more of a normal'/ centered feeling which in turn in actuality is what these meds are supposed to accomplish! And makes it less addictive! Thats really all I seek is to feel compared to the highness effect. Ive thought of stepping up the dosage, but Im afraid all Ill get additionally is more of a high at first, and than unGD Star Ratingloading...

    Apparently the oxygen producing unit is made by Honeywell. To anyone who has been following Honeywell's escapades over the last 12 years since they were acquired by Allied Signal, that perfectly explains the problem. Management abused their US workforce so badly that their experienced people left the company. Those that didn't voluntarily leave were axed. Those that remain have minimal experience and little motivation. Tens of thousands of jobs have been handed over to China on the blind assumption that all it takes to build a product is a warm body. No doubt CEO Dave Cote (Obama's business buddy) is maneuvering to keep the company name out of the spotlight and deflect the blame away from the company. Recall the so-called "unintended acceleration" issue with Toyotas and how it was all over the news? That's exactly what Honeywell does not want, and that explains why you don't see the company name in the news reports. An investigative journalist could punch his own ticket if he got hold of the truth.

      Raph: I said it because it's true. Dave Cote and Obama were all buddies when Cote thought that Obama would name him to a new business advisory panel. Subsequently, Cote did not get that job (I think Immelt of GE got it) but you can be sure that Cote still cultivates the relationship for both ego and business purposes.

      Where were you 10 years ago when VP Dick Cheney's ties to Haliburton (you know, the company that received billions of dollars in no-bid contracts during the Iraq war) came to light? You certainly weren't decrying the administration's inappropriate relationships then, now were you.

        What the heck does 10 years ago have to do with malfunctions in the F-22 oxygen system, idiot? My point is that Cote would not hesitate to use his relationship with Obama if he thought it would help keep a defective Honeywell product out of the spotlight. Get a grip, you partisan twit.

    This plane was designed and built to fight the last war, and is well suited to perform a mission that no longer exists. Our current arsenal and military are more than capable of protecting our interests – and the future is in newer technology and UAVs. Instead of continuing to build these dinosaurs to support jobs in the aerospace sector and the Air Force, why not use it for something more useful – like schools, roads, medical care (or even other defense areas) – which would add even more jobs and provide some useful benefit to the country and society.

      The last production F-22 was delivered to the Air Force several weeks ago. They are, in fact, not being produced anymore.

      It's also well suited to fight present day conflicts. Its range and speed allow it to swiftly reach any part of somewhat large nations like Afghanistan, drop their precision payload, and get out. While this is, predominately, an Air Superiority fighter in an era in which we rarely ever need to expend effort to assert Air Superiority, it still performs the ground attack role exceedingly well, which is what we need for current conflicts.

        The F-22 is not a servicable aircraft. The F/A-18E is the servicable aircraft over China, along with a bone perhaps.

    What Company made these planes anyway. How long were they tested before turning it over for operational readiness. Its not the military who is the problem. It is the large low bid, only bid companies who rip the government off for a poor quality product. Who cares if it kills a couple guys and families sue them, it is cheaper to pay a settlement to shut them up and hide hte cause of the problem like any other large corporation does. Lets blame Obama, for sure it was his administration that pushed this sale through to what is flying today. NOTlets go back 8-10 years. Some people should be in Jail for this and its not the pilots and mechanics who brought it out in the open.

      You call a half a trillion dollar bid, a low contract bid? I think your assumptions would have worked, but there's so much money thrown at this project, that the problem is not with the aircraft itself, but with the subcontractor that installed the oxygen lines.

    It is a matter of national security to get this problem fixed once and for all. Those jets are part of our national defense system and they need to be back in service as of last week! What's wrong with this nation, with the American mind set, that we can't get it together to solve this problem once and for all!?! Have you people been sucking up too much TV!?! Come on!

    I am not one to blindly trust "the government" or "the military", but, in this case, for obvious reasons, it is in their interest to find the cause and fix this problem ASAP. If I was a betting man, I would say it has something to do with VOCs (i.e. the things that cause the "new car odor") are still working their way out of the various high tech coatings and materials that make up this plane and they are making people a bit woozy. This would explain why it is affecting both pilots and groundcrew. Moreover, it would explain the vague and generalized answers we are getting from the military since they don't want the rest of the world to know exactly what kinds of coatings and materials are being used in this state-of-the-art jet. In any case, there are plenty of smart guys in the air force and in the company building these planes. It is time for them to figure this out and fix it and move on. No more games and no more covering ones' butts. Just fix it.

      Being a mechanic in the military myself, I would highly encourage the air force to check refrigerant systems. My intuition is telling me that refrigerant from a coolant system leak could be collecting in their lungs, undetectable, except for hypoxia/suffocation type symptoms, it would not reveal any other type of symptoms. Refrigerant collects in the lungs, and displaces oxygen because it is heavier than air, and being a gas itself would be relatively difficult to detect in the lungs of pilots and mechanics, but would silently fatigue and suffocate those exposed to it. But, I am not an engineer, I do not have a degree, I is dumb, so anyone important that reads this should probably just disregard, or take the credit because they are smart.
