It might be a bit of a wordy message but I suppose there could be:
"Your plane was shot down due to XXX damage (most) from a P-51 flown by ______, XXX damage from an F4U-1A flown by ______, XXX damage from a P-38G flown by ______, XXX damage from a B-17 gunned by ______ and XXX damage (least) from a Jeep gunned by ______."
Or .... it could stay simple and just be the abridged version. Perhaps a preference toggle in flight options?
