I recently found this sentence in a book ... "The Checkertale Clan:The 325 FG in North Africa and Italy" by E.R. McDowell and William Hess, pg 56;
"An unusual encounter took place on 24 August 1944 when the Group ran into a captured P-51 painted black over-all with yellow stripes around the wings. It was flying in a mixed gaggle of about 40 German aircraft...."
I've never heard this before except for stories of captured B-17s and 24s directing fighters onto bombers. And most captured stock was with KG 200, correct? Never heard of something like this being used to fight with a regular Gruppe or such!
Interesting unless this has already been discussed and I haven't found the thread yet.
