The crew were taking part in testing in conjuction with a Ministry of Supply radar unit positioned on the summit of near by Drum. After completing the test Flt Lt Bell radioed to the radar operators stating that they were returning to base. When nothing further was heard from the crew a search was initiated, the radar unit had tracked the aircraft until it was some 10 miles north of Drum but there was no track beyond there. Later the wreckage was discovered by search parties on the northern side of Carnedd Llewelyn. The aircraft had been flying in patchy low cloud on an easterly track when it struck Carnedd Llewelyn some 300 feet below the summit on the ridge connecting the mountain to Foel Grach. The forward end of the aircraft broke up leaving many pieces of structure from the forward fuselage on western side of the ridge. There is then a break in the wreckage trail which starts again on the eastern side of the ridge on the slopes above Ffynnon Llyffant. The centre section, wings and rear fuselage eventually crashed to earth near this small lake, though other pieces did travel some distance beyond here.
The reason for the aircraft being below its safety height could not be ascertained, a possibility was put forward by the crew’s commander as engine failure due to icing. That day icing conditions were expected above 3,000ft.
