The landing strip at Wongrabry Station is 2, 600 feet long and is aligned in approximately an east-west direction. The station homestead is near the eastern end. The aircraft was fitted with dual controls and it is not known which pilot was controlling the aircraft. The aircraft took off into the west and made a partial circuit to the south of the airstrip, approached the strip from the east, passed over the homestead at a height estimated at between 600 and 800 feet and then new parallel with and above the strip. At a point approximately above the western end of the strip the aircraft completed a controlled roll to the left through 360 degrees, recovered and continued westward in level flight. About 1 1/2 miles beyond the strip it zoomed sharply upward into a stall turn type manoeuvre to the left and entered into a steep 70 degree dive. As the dive progressed the speed increased to about 200 knots and the dive angle progressively decreased. When the aircraft was about 200 feet above the ground it had attained a nearly level attitude but was still descending. It passed out of sight of eye witnesses and struck a tree and then the ground.
