This film is unclassified. It is a 1940’s era, black and white movie. The Navy Department presents a United States Navy training film. Produced for the Bureau of Aeronautics by Wilding Picture Productions, Inc. Copyright 1943 by Wilding Picture Productions, Inc. The Inverted Spin. Intermediate Acrobatics, Part VII. The purpose of the film is to teach pilots how to enter into – and pull out of – an inverted spin maneuver. The movie opens with a forward view of a plane; our viewpoint is from behind the propeller 1:05. A plane is flying upside down 1:25. The plane is falling and spinning upside down 1:40. A plane flies with two passengers in an open cockpit 2:00. Pilot adjusts dials to get ready for an inverted spin 2:30. A plane flies and gets ready to perform the inverted spin maneuver 3:00. The plane flies upward and into the inverted position 3:15. The plane falls and spins downward 3:30. An aerial view of the pilot’s feet inside the cockpit 3:45. The oil pressure gauge is shown 4:20. The plane flies straight 4:30. The plane flies upside down and spins facing downward 5:16. The plane goes into an inverted spin 5:50. A plane flies directly downward and then up again into an inverted position where we see the pilot begin to control the spin 6:30. We have a view from behind the propeller 6:53. The horizon appears before us 7:02. We have a pilot’s view of the horizon as the pilot spins the plane into different positions 7:40. Words appear on the screen. “The inverted spin bears some relation to the normal spin in that any plane that is difficult to spin may also be difficult to bring out of a spin.” 7:50. “The higher the altitude at which the plane is spun, the more difficult it will be to bring it out. An increase in altitude has the same effect as an increase in wing loading.” 8:00. “The inverted spin differs from the normal spin in that recovery from an inverted spin is often more rapid and more certain than recovery from the normal spin.”. 8:15. A plane flies straight up to attempt the inverted spin 8:23. Pilot controls are adjusted in case of an emergency 9:00. Plane falls to earth in the inverted spin and then pulls out, perfectly level 9:45. The Navy Department, United States of America.
