Welcome to Warbird Wednesday! Today we are visiting our third night fighter, the British built Boulton Paul Defiant. With its first flight in 1937, the Defiant was best at approaching and attacking other aircrafts from underneath. Their success during the night was obvious, as they would be able to sneak up without the enemies knowledge, leading to 1,064 models being built. They eventually were replaced, as there were numerous deaths and accidents. They went on to be used in gunnery training, target towing, electronic countermeasures and sea-air rescue, being completely retired in 1945.
