High Quality Content by WIKIPEDIA articles! 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 bailed out after the aircraft struck, followed shortly afterwards by the injured pilot of the lower Anson. 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 was then able to make a successful emergency landing in a paddock near Brocklesby. All four crewmen survived the incident, and the Ansons were repaired and remained in service with the Air Force.
