John Ernest Voisin [00001] at the controls of an H2X radar set in a North American B-25 “Mitchell” bomber, Yuma Army Air Field, Yuma, Arizona, 1945.

This is me in front of the radar set in a B-25. My left hand is on the controls of the "computer box" of the set. The scope and main control box are to the left of it.
