The Anson Brothers

On 29 September 1940, a mid-air collision occurred over Brocklesby, New South Wales, Australia. The accident was unusual in that the aircraft involved, two Avro Ansons of No. 2 Service Flying Training School RAAF, remained locked together after colliding, and then landed safely. The collision stopped the engines of the upper Anson, but those of the machine underneath continued to run, allowing the aircraft to keep flying. Both navigators and the pilot of the lower Anson bailed out. The pilot of the upper Anson found that he was able to control the interlocked aircraft with his ailerons and flaps, and made an emergency landing in a nearby paddock. All four crewmen survived the incident, and the upper Anson was repaired and returned to flight service.
