In 1967 the single-engined Beagle Pup made its first flight and was made and sold in greater numbers until the company's bankruptcy. The receiver sold a number of incomplete Pup aircraft which were then completed by other companies. At the time of the company's bankruptcy in 1969, the military Bulldog was being developed from the Pup by Beagle; Bulldog production was then completed by Scottish Aviation at their Prestwick factory following the demise of the Beagle Aircraft company. At the turn of the 21st Century, many Bulldogs were being sold by air forces to civilian operators, in much the same way that Austers were transferred from Army or RAF squadrons during the 1940s and 1950s.
