Air Force zeroing in on cause of T-6 hypoxia problem

JB SAN ANTONIO-RANDOLPH, Texas ? Since late last year, a rash of unexplained physiological events such as hypoxia has caused dangerous breathing problems for pilots of T-6 Texan II training aircraft, and led to multiple groundings.

But now, the Air Force is finding more clues, and coming closer to solving the problem once and for all, said Lt. Gen. Steven Kwast, head of Air Education and Training Command.

?Within the next couple of months, you?re going to see some communication from [the safety investigation board at Edwards Air Force Base in California], that they are starting to really discover the root cause here,? Kwast said in a July 23 interview at his office here. ?We?re finding insights that we did not know before, that will help us understand what?s going on and give us a pathway to solving the problem permanently. We?re getting close, and you should see something soon.?
