Disobeying orders is obviously a big issue but to compare someone that disobeys orders with the Germans is just wrong(as long as their not shooting friendlies).
Ground them or remove them from the army or even throw them in jail for awhile but to kill them or sentence them to death would just be a murder committed by society.

If they refuse to obey the order in the battlefield I'll shot them myself - without trial, on the spot.

That's why officers are equipped with sidearms.

So you would have shot P/O Paszkiewitz who shot down a german plane during a training mission, thus disobeying orders from his British officer?

What if the renegade pilot is from the Luftwaffe, being chased by his former squadmate(s). As an allied pilot, how do you know he's friendly? Will the attacking pilot(s) turn back and the renegade waggle his wings? Was the pilot a double agent or a spy stealing a new aircraft?

Court-martialed, for sure.
Shooting on the spot is for ground crews only(kinda hard shooting a pilot in plane several hundred yards away, no?).
Obeying orders is probably the most important skill for a pilots - you don't have to think and you're not aloud to have any emotions.

F.i. you lose a wingman, ground control orders you to retreat but instead you decide to revenge your buddy and shoot down the enemy plane.
In Switzerland they would credit you the kill and right after that revoke your flying status. Simple as that.

An exaggeration. Pilots of polish squadrons would have 50% less aircrafts shot down on their account during bob if they were acting like they were told to ;)

And yet the Brits still let them fly.
That only shows how desperate they were. :cool:

OK, you went from "I'll shot them myself - without trial, on the spot" - quite stupid, imo - to, "court-martial" - reasonable, while debatable

Quite a leap

I understand your first statement was just a big-mouth overreaction.

No, actually it's the only thing you can do on the (infantry) battlefield.
But if you prefer to discuss it out or risk mutiny, do whatever you think is best.
Don't forget to tell the enemy to hold their fire till you're done.

Have you ever served?

Sending 18 year olds with only few hours of basic training into battle is a sign of desperation.
Letting foreign experienced veterans fly hurricanes is not. It's opportunism.
