Speaking of: There was a Navy T-45 pranged in eastern Tennessee today. Killed both crewmen. There are unconfirmed rumors that the oxygen system has been becoming toxic to pilots lately. May possibly explain how neither crewman ejected before the crash. Hard to do if you've passed out from hypoxia/poisoning. I would think the Instructor would be well trained in what to do, though. The Navy has some really good quality training devices for hypoxia training in particular, but it can be so insidious, it can get ya before you can recognize it and grab the green ring...

Still, my thoughts go out to the families. I hope they solve the mystery of the crash cause, just to give them closure.
