That doesn't sound right. Surely if the masks deploy and the O2 is used, if you climb back to high altitude again, what are the passengers to do if you have a repeat ? Or the crew for that matter?
Suspect reporting here.
"These planes fly at an altitude that at Mount Everest is called the death zone because of a lack of oxygen," aviation expert Greg Waldron of Flight Global told the BBC.
"So the pilot absolutely has to bring the plane lower. Otherwise, crew and passengers would get unconscious."
'The death zone'? Really, where do they find these 'experts'.
