Percival Proctor
The Percival Proctor was a British radio trainer and communications aircraft of the Second World War, developed by Percival Aircraft Limited from the Vega Gull tourer. Ordered to Specification 20/38, it first flew on 8 October 1939 and remained in production through the war; 1,143 were built, 250 of them for the Royal Navy. Successive marks trained radio operators — the Proctor III for Bomber Command among them — while others flew communications work, and the enlarged Proctor IV stayed in RAF service until 1955. A civil Proctor 5 followed after the war, but the wooden fleet was grounded in the 1960s as its glued joints degraded; a few survive, in museums and, rebuilt, in the air.
