AIRCRAFT RECOGNITION - SYCAMORE AND DRAGONFLY [Main Title]
One of a series of training films to aid the recognition of airborne aircraft when viewed from the ground, featuring the Bristol Sycamore and the Westland Dragonfly. The helicopter plays a limited but very valuable role in the modern Royal Air Force of today. The identification of helicopters demands new skills of the observer to identify small but unique differences to the familiar layout pioneered by Sikorsky.
The Sycamore: Several development aircraft were built leading to the first military version, the Sycamore 8 C 10. The film cuts to a Sycamore in flight as the camera follows the identifying features described by the commentator. No diagrams (animated or static) appear in the film, which relies solely upon photography of the aircraft both on the ground and in the air. The basic design of the Dragonfly differs from the Sycamore and is thus readily identified, as the footage and commentary repeat the cycle of observations.
Film cuts to aerial view of an aircraft carrier. A series of trial flights from the deck has lead to the introduction of the Dragonfly for use at sea by the Royal Navy. The American version of the Dragonfly is used for a variety of purposes on land and sea, including the Korean War.
The film closes to the Sycamore and Dragonfly flying about 100 feet apart, hovering, landing, and taking off in synchronisation, to allow the observer to make a direct comparison of the salient features of each helicopter.
