A remarkable story, this aircraft was one of six Mustangs at Emu Field subjected to an atomic bomb test in 1953. Fourteen years later after an epic repairs it was flown from Emu to Coober Pedy by Tony Schwerdt without approval and later to Parafield with approval, however registration from the CAA was not forthcoming until four days after A68-1 had been sold to the U.S. Damaged in transit to the USA it was again abandoned for another ten years before being restored to flying condition.

With some repairs, A68-1 was able to be flown out of the Totem nuclear test site where it had been subjected to two blasts in 1953.

The first Australian built Mustang assembled from parts from North American. Was one of the aircraft parked at Emu Field during the Totem atomic bomb tests in 1953. Its condition in 1967 was such that it was decided Tony Schwerdt should fly it out, first to Coober Pedy (without approval) and then on to Parafield (with approval). After failing to get A68-1 registered in Australia it was shipped to the US where it became N7773.
