Probably the closest friend my grandfather had during his aviation adventure was J. Earl Steinhauer, an important figure in American aviation in his own right.  After World War II he was the Assistant General Manager of Fairchild Aircraft in Hagerstown, Maryland.  One of the aircraft they produced was the C-119 “Flying Boxcar” which saw service in both Korea and Vietnam.  Below are some sketches of the plane, a couple with Earl’s name on them.
