Had a friend that was involved in testing the A-26 with the 75 mm canon installation. He mentioned coming back from the test range with palm fronds in the bomb bay doors once.... Held one of the poles for Art Scholl doing an inverted ribbon pick up..... Didn't have to look up much to be eye to eye with him. Working that close to the ground at any speed, inverted or right side up takes titanium gonads and great skills.
