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 managed to land safely. Both navigators and the pilot of the lower Anson bailed out after the aircraft struck. The pilot of the upper Anson, however, found that he was able to control the interlocked aircraft using his ailerons and flaps, coupled with the still-functioning engines on the machine underneath. He then 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.
