The aircraft used to play "Mary Ann" was a B-17B, one of 19 that had the gunners' bubbles replaced by the flush gun positions of the B-17C and B-17D. This aircraft MAY have been aircraft 38-583 or possibly 39-010. Also, aircraft "18" in the movie is 38-269. Pause the scenes where John Ridgely has walked in front of the daytime flight line with numbers "18" and "05" in the back ground, and, as he is talking to the crew in the bomb=bay, look through the gap between the bomb bay door and the fuselage: as you pause and forward frame-by-frame, you will see the tail of "18" just barely enough to see the numbers "8269" showing! This means that aircraft "18" is actually B-17B 38-269.
