Consider though the tactical situation. The enemy are advancing at great speed. Aeroplanes are our most valuable asset. The aircrew will jump in them and fly away, yes I suspect grateful to be saving their own lives, but also those aircraft are then saved to be used in anger on another day.
Isn't this what we used to do on the old Cold War type exercises - a "Survival Scramble".
I still like to read digs at any aircrew though.
