Frankly in the oxygen mask case. I never heard of an issue with it before. All I know is that if they deploy. I put the nearest one on. The technicalities are lost on me. The lack of any communication from the flight deck would imply to me that they were a tad busy and that this was an emergency. All pretty obvious. I would have thought, unless, apparently, you are well travelled polar explorer. Who quite frankly seems to have all but panicked. Then compounded it by mouthing off to the BBC.
Well said!!!
