What's going on with oxygen systems in military aircraft?...

This is, IMO, getting ridiculous!: ... bad0d5987f

I remember hearing, in a 60 Minutes report, about problems with these systems in F-22s, but those were fixed, and now it seems like all our military aircraft are being effected by these issues.

A lot of military aircraft have moved from liquid oxygen tanks to generating oxygen from onboard oxygen generation systems. The main advantage going from liquid oxygen tanks to an onboard generating system is endurance; pilots can fly much longer breathing from OBOGS than they can from a LOX tank, and with today's missions being longer than before, having the extra endurance is becoming essential.

Not to mention that LOX is extremely volatile and potentially dangerous; special precautions need to be taken when handling LOX, and if LOX spills onto an asphalt surface or gets soaked into a oily rag, you got a ticking time bomb with the potential for a MASSIVE explosion.

Finally a bit of movement on the hypoxia issue with US military aircraft.

Air Force taps brigadier general to look into hypoxia, related issues

The Air Force has assembled a team to look into the rash of hypoxia and other alarming physiological events endangering the safety of pilots.

Brig. Gen. Bobbi Jo Doorenbos will head the Unexplained Physiologic Events Integration Team, the Air Force said in a release Monday. The panel will try to find ways to eliminate those events or minimize their impact, the Air Force said.

“As part of the integrated effort to address physiological events, the Air Force is providing more resources to understand UPEs, standardize response actions to such events and assess options for more robust aircrew training to recognize and respond to these events,” Doorenbos said in the release. “Our ultimate goal is to prevent UPEs.” ... ed-issues/
