very wrong, unrescuable.
'Pear-shaped' is an RAF euphemism for 'tits-up', which is itself a euphemism for 'dead'.
The Oxford dictionary definition cites an RAF source in 1983. I was an RAF pilot in 1983. The reason no-one will confirm the meaning officially is that it's rude, hence the rubbish about aerobatics. Loops that go wrong are egg-shaped, and have always been referred to as such.
