Navy Rules Out Suspected Physiological Episodes Cause While Super Hornet Rates Grow in 2019

CAPITOL HILL — The Navy has ruled out breathing air contamination as a cause of physiological episodes, but a complex set of conditions – including both cabin pressure issues and human factors – has led to the rates of pilots experiencing PEs this current fiscal year being back on the rise.

Though the service has not yet pinpointed a cause – and likely won’t ever find a single root cause – other gases or contaminants have not been found in breathing air coming from the jets’ Onboard Oxygen Generation System (OBOGS), the Navy said in a little-publicized news release this week.
