Badger Apr 2021 10:47am, 20 Apr 2021 13,761 posts	0 Badger [Jet engines compress air heavily, so the oxygen content where the ignition happens is a lot higher than it will be in the hold.] In fact a fair proportion of the thrust is from air pulled in, compressed and pushed out bypassing the combustion chamber entirely- the engine burns enough fuel to keep the turbine, compressor and fans running. So it’s not completely bonkers at first sight, but it does sound like a bit of a Hail Mary move.
