Just noticed this one in Sgt Fury #32 (July 1966):
was a character in Joseph Heller's famous novel, Catch-22. In a memorable bit in that book, Doc Daneeka "dies" when the plane he is supposedly in crashes into a mountain. Actually, Doc had simply signed his name in the log book for that flight to satisfy some regulation, but not gotten on the plane. Regardless, the military (and many of the characters in the book) treat him as if he no longer existed.
