Operated by 1674 Heavy Conversion Unit. After taking off on a practice flight, the aircraft continued straight ahead towards Antrim, flying very low for no apparent reason and against instructions. It then began a wide turn at high speed, but lost height and struck trees at Masserene Estate, Antrim. (some records state Shanes Castle) It cut a swathe through the trees before crashing on open ground immediately south of the Sixmilewater, on the site what is now the Antrim Forum, it caught fire and burned out. Warrant Officer L.W. Lenz, Flying Officer G. Fraser, FS H.V. Heaton, Sgts, J.L.Snider, L.M. Hembruff, and four of the crew, not Canadians, were also killed.
