A North American B-25 “Mitchell” medium bomber aircraft, U-407, on the flight line at Yuma Army Air Field, Yuma, Arizona, 1945. John Ernest Voisin [00001] denotes this picture "Our Ship" because he used it for radar observation bombardment training. This aircraft could be a B-25J or a TB-25J, which was converted for use in training.
