Hmmm, flight safety from afar from info in disjointed articles online, from 'concern trolls'. Below is a quote from the URL immediately above the F-35 OBOGS graphic not quoted at the time:
"...Maj. Rebecca Heyse, spokeswoman for the 56th, stressed that flight operations are currently only suspended for one day, and will resume on Monday...." [at LUKE AFB]
After some 95,000 F-35 flight hours this is the first we hear of any 'hypoxia or related events' confined to LUKE AFB F-35s. As for testing previously one would assume the life support systems would have been the first to be tested thoroughly. Previously whilst USN OBOGS undergoing scrutiny with
aircraft not grounded Shornetwise & Goshawks confined to limitations it was usually stated that the F-35 had no such issues.
Article here mentioned above has some balance without sensationalism:
