Sources: Flight suit could be cause of oxygen loss in F-22 flights
By Mike Mount
Air Force investigators believe a specialized flight suit could be partially responsible for some pilots experiencing a lack of oxygen while flying the F-22 fighter jet, according to a report by Air Force investigators.
Investigators are focusing on part of the suit, called the "Combat Edge," which hampers breathing and causes oxygen loss when combined with a physiological condition that collapses air sacs in the lungs, according to details of the report that were shared with Security Clearance.
The findings are expected to be part of the first monthly update by Air Force investigators to Secretary of Defense Leon Panetta to be delivered later this week or early next week, according to sources familiar with the investigation.
Last month, Panetta ordered the updates on the investigation after the Air Force could not identify the cause of the continued issues with pilots complaining about coming close to passing out while flying the plane, which the service called "hypoxia-like symptoms."
Combat Edge is a vest-like garment that expands and contracts on a pilot's torso to fight the effects of severe G-forces experienced while flying the F-22. The problem being looked at is that the garment may restrict the pilots' breathing beyond what is intended, according to sources familiar with the report.
Another possible problem for pilots, the report is expected to say, is a condition called acceleration atelectasis, which causes a pilot's lungs to not effectively deliver oxygen to the bloodstream. The condition for F-22 pilots is caused when extreme gravity and breathing almost pure oxygen in the F-22 cockpit partially collapse air sacs in the lungs, according to the sources.
Acceleration atelectasis causes a heavy cough, which F-22 pilots have called the "Raptor cough" after the nickname of the fighter, "Raptor."
Pilots have complained about the cough in connection with the hypoxia-like conditions as they fly the F-22, the most technologically advanced plane in history, often at altitudes much higher than regular aircraft fly. The pilots also perform maneuvers that put their bodies through extreme conditions.
In an e-mail response to questions by Security Clearance, Air Force spokesman Lt. Col. John Dorrian said, "Recent testing has identified some vulnerability and reliability issues in the upper pressure garment worn by F-22 pilots. Air Combat Command has directed pilots to remove the upper pressure garment during routine flight operations, and Air Force officials are developing a fix to overcome the identified issues."
The findings in the update report to be given to Panetta are not final, according to the sources. Air Force officials say investigators are narrowing down the cause of the problem, which has intermittently plagued the aircraft since 2008.The problem compounded in September 2011 as more pilots complained of experiencing the symptoms.
The Combat Edge problem does not explain why some mechanics have also suffered from hypoxia while working on the planes on the ground.
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.
Investigators initially pointed to an onboard oxygen generating system that pilots used to breathe as a possible cause.
Lockheed Martin, the maker of the jet, was given a $19 million contract to install a backup oxygen system in the F-22 last week.
Last month, Panetta mandated that all F-22 flights "remain within the proximity of potential landing locations" to ensure the ability to recover and land should a pilot run into "unanticipated physiological conditions."

I had undertaken a task that I realized i was beginning to feerl was beyond individual resources carry out.
I had asked partner and colleague if I will
organize a workshop the actual New England area thyat he or she would teach.
After many months of collecting information, We're at the time
of choosing and committing to a conference center.
Next would comke the advertising, invitations, mailings, registrations, etc.
It happened few years ago in the early stages of my new career,
and Being beginning to feel i was in over my head.
I started to wish I had not started the project but was
afraid to say anything, because I didn't want to permit my friend down.
Create a reasonable profile. If your proile is interesting and lively itt really is goin attract if
the process. Avoid using negative terms like loner, loonely etc anyone may end upp behind.
Act as truthful simply too. This can save you from a lot of problems aat a later stage.
Next, you could possibly want to purchase around. Could certainly ask people you know for references to the
attorney. Sppecially if youu know any people you would trust
for every good opinion, which have goone the divorce.
Your articles may be free to recommend a beneficial divorce lawyer
for your company. Many attorneys are pro's at divorce and can be in fact, not
okay attorneys. However, you do want to rent a professional that makes a speciality of this specific area.

Another idea to imagine before venturing into online
trading, is to know one self. Youu simply have to know the person you
would be. Then, you can find or build a trading system to suit your personality.
It is similar to finding a mate. Calordies from fat compatible
a person with your stomach or mate, the easier itt wiull be for which trade or get in step.
Online trading takes more preparation and decision making because you are virtually for
your own. This is oone reason you should never buy
some automated trading on the internet system from the
rack. Thee hho booster doesn't fit to your trading style, online trading will become youhr worse headache.
If churches tuat are asking hard questions and being radically inclusive
today are not irritating with other churches together with the power structures individual society, maybe our questions
arre not honest enough or perhaps they're not hearing us
- not seeing what we're wantiung to do. The Church become irritating when we're true towards
the One we follow. Jesus was irritating. He iritated the powers that were
and the powers that still are. Let's walk together to act as a prophetic voice and
an irritating presence too the society additionally,
you will the Church so that justice will start
too flow like rushing water around us.
We often more ready to stay miserable than to push into the unknown. But learnjng comprehend the unknown is the envelope against wich all manifestation and creation pushes.
It isn't fair, either to the other parent or to the child too impose your conflicted emotions on him.
Everybody has a right to meet the world on our own terms.
Hopefully, we can ciunt on our parents to provide us
with the toools we have to ddo it.
