“Do they say why the jet lost pressure?”
Headline??? /s
The NTSB report is preliminary, but answers most of the early speculation. I can’t source a link to the preliminary report itself and won’t be expending any more time on it.
Final report isn’t expected for another year.
I’m wondering who owned this aircraft.
Overdue maintenance.
Missing oxygen masks.
Low O2 levels.
One pilot.
For this type of aircraft, truly unreal.
