First shot ... but a continuity error !
The Boeing B-17 Flying Fortress is seen through shot made with a real aircraft (gunners stations, ditching) or through a set (of poor quality) or a model.
The movie was filmed in one week at a time the B-17 was nearly phased out of all the US forces (Air Force, Navy and Coast Guard), being only used for Search and Rescue or as Drone. Several action are taken from other movies (eruption, dinausor) and the ditching is from a movie used for instruction purpose : War Office's movie Training Film I-3385 (1944) ... including the bomb run on the enemy vessel action. Only the cockpit shooting was a new material as the captain is the main character and the face couldn't be the same of the instructional film.
