One of the original PEs at Luke, that resulted in the aircraft being grounded was an OBOGS failure in flight. The pilot gave an anonymous interview
to Aviation Week. He reported that during the flight there was a momentary catch in the oxygen through the mask, and then an OBOGS failure warning
when the oxygen started up again, but he immediately began showing signs of hypoxia. A few weeks later, another pilot had a hypoxia event, and the
pulse oximeter he was wearing showed a momentary drop to 84%, but was back to normal on the flight back to Luke.
