Summary: Fragmented film of events at an RAF air display at Southampton, June 1930.
Description: A civilian, presumably the inventor, describes the workings and advantages of the Westland Pterodactyl IV, a 'flying wing' aircraft beside him. A test pilot takes off in the Pterodactyl. As part of the air display a biplane, recreating the First World War, makes a 'balloon busting' attack on a tethered kite balloon, which bursts into flames. A woman's voice can be heard crying "Oh, look - Oh !" as this happens. The Pterodactyl comes back in to land. RAF rescue launches race each other in line through Southampton water. Two Supermarine Southampton flying boats overfly the coastline. One comes down to land in slow motion. Another taxies on the water. A Vickers Vildebeest torpedo bomber prototype (designated O-3 on its side) take off for a trial flight and drops its torpedo on a mock attack.
