- never. But I have run extremely short on 3 occasions and force-landed once, so I don't think I need your 'experience' there, thanks. One of the three would have been fatal within 5 minutes if I had not made the tanker over the North Sea in February, but that is not relevant in this (RyanAir) thread.
BOAC with the greatest of respect - how, exactly, did you know it was "within (less than) 5 minutes"?
When you get down to fumes and it all goes quiet - it's time to blame miscalculation - but what?
I just think passengers assume better odds when flying, between life and death.
PS. Death can be fatal.
