Auster Atom
The Auster J/3 Atom was a 1940s British single-engined two-seat high-wing touring monoplane built by Auster Aircraft Limited at Rearsby, Leicestershire. History. The Atom was an attempt to create a lower-powered version of the J-2 Arrow. A modified Arrow was flown with a 65 hp Continental A65-12 engine and designated the J/3 Atom. Only the prototype, registered "G-AHSY", (c/n 2250) was built as the aircraft was not developed further. Another example "G-AJIJ" (c/n 2401) was not completed. The sole J/3 was dismantled at Rearsby in 1950 and was rebuilt  to J/4 standard with a new registration "G-AJYX" and c/n 2941. It crashed near Melton Mowbray on 22 April 1951 after a pilotless take-off from Rearsby. The Continental A65 engine had been replaced by a 95 hp Blackburn Cirrus Minor II. This aircraft has since been deregistered by the CAA.
