Big concerns
My two main concerns (in this specific context, there are many others for this bird) are:
Why does it take the pilots suffering hypoxia to expose the problem? In an aircraft already laden with sensors, a pulse oximeter for the pilot, or an oxygen sensing system for the oxygen system makes... sense?
I'm going to assume (benefit of the doubt, but not holding my breath (hyuk!)) that they at least carry small bottles of supplemental oxygen to deal with ejection at extremely high altitude, but why would they not include an emergency bottle for the main system?
