 The U.S. Air Force has grounded its entire fleet of F-22 Raptor fighter jets across the United States because of possible malfunctions in the planes' oxygen supply systems.  

 

Pilots flying the F-22 Raptor jets have reported hypoxia-like symptoms which can occur when the human body is deprived of oxygen.  

 

These reports may provide clues as to why an F-22 pilot from Joint Base Elemendorf-Richardson was killed during a training exercise in November of last year.

 

However, that crash is still under investigation.  

 

The Air Force has yet to determine how long the grounding is expected to last.
