They seem to have done things differently in the 301st Group down in Fogia. My father flew with about 10 different pilots to get to his 50 missions. They seem to have put the crews there together pretty haphazardly. Of course, there was a constant demand for replacements due to injuries and downings.
Later it was increased to 30 missions.
I knew fighter pilots did many more sorties but I didn't know the heavies did.
Thanks for the reply.
