It opens with a view of an airplane landing at an airport and scans across TWA and United Airlines DC-3 and Convair passenger planes (:24-42). Crew and passengers disembark from a United Airlines Mainliner DC-6 plane (:43-:50). A maintenance man perches on one of the plane’s giant air-cooled engines (:51), complete with metal propellers that generate thousands of horsepower. (:52-1:00). They have variable pitch, controlled by the pilot (1:03), and are driven by a piston engine. The propellers begin spinning and the plane takes off (1:04-1:30). A propeller spins on a line of experimental military planes (1:34-1:52). At (1;49) Grumman F8F-2 Bearcats are shown on the flight line. The mechanics and limitations of how a piston engine works in a propeller is illustrated (1:53-2:15). The solution was a jet propulsion engine (2:16-2:37). The mechanics are illustrated by a child blowing up and releasing a balloon (2:37-50). Newton’s ‘third law of motion’ is explained, using an illustration of a balloon (2:57-3:40), a child jumping out of a Radio Flyer wagon (3:41-3:56), a water sprinkler (3:58-4:13), and compressed gas powering a toy model (4:14-4:25). Compressed gas is further illustrated as to how a turbo-jet engine works, which uses a built-in gas turbine (4:26-7:16). A turbo-jet engine is shown up close, including its fuel pump and an oil pump (7:17-7:39). A Navy pilot boards his McDonnell F2H-2 Banshee fighter jet, takes off, and multiple flying angles are shown (7:40-9:44). The mechanics of the efficiency of a turbo-jet engine is illustrated, including a turbo-prop, a pulse jet, and a ramjet (9:45-11:05). Another type of jet propulsion is rocket propulsion, shown by its launch (11:06-11:29). The Navy jet aircraft is shown again, including multiple planes in flight (11:30-12:14).
