AIRPLANES APPROACHING THE SOUND BARRIER MACH 1 SHELL EDUCATIONAL FILM 74842

“Approaching the Speed of Sound “ is one of the “High Speed Flight“ films made by the Shell Oil Company in the 1950s. Directed by Peter de Normanville, the movie features many early British and American jet aircraft. The film features a basic demonstration of how sound is produced and how it travels through air. The inter-relationships between the speed of an aircraft and the speed of sound is established. The term mach number is defined and shock-wave formation around an aircraft wing is illustrated. Some of the planes featured include Comets, Meteors, Canberras, and more. The film includes footage of aircraft approaching Mach 1, including turbulence and instability as seen by the pilots. Wind tunnel tests are also shown as part of the demonstration, producing shock waves and control troubles.
