From Bob Spurdle's (CO of 80 Sqd 2nd TAF, late `44) memoir 'The Blue Arena' - re this topic..
"On Sortie No' 551 some USAAF Mustangs jumped us. Enraged, I turned on my particular
tormentor & scared him fartless by firing bursts 1st on one side & then on the other,
while he twisted & turned helpless against the far superior Tempest.
Formating alongside I shook my fist at the stupid jerk & then zoomed away.
We should've hacked a few down to teach them aircraft recognition.
We were sick of their trigger happy stupidities.
One of the wing's pilots painted a white star on his machine, adding it to his string of swastikas.
He was told to remove it.
The squadron commanders of the wings under Air Vice Marshall Broadhurst's control were assembled
at Eindhoven for a general briefing on future operations & on the war's progress.
The AVM, in passing, told us that if our aircraft were subjected to any more bouncing by our gallant
allies, we could retaliate & no disciplinary action would be taken.
An extraordinary scene followed - cheering, back-slapping, laughing pilots surrounded our popular commander.
We'd had more than enough of this sort of aggravation."
