Spitfire P8594 at Catterick airfield.
At 11.15hrs on 20th September 1941 the undercarriage of this 145 Squadron aircraft would not retract after taking off from Catterick airfield with the pilot detailed to carry out a formation flying exercise.
On his return to land at Catterick at 11.30hrs the pilot forgot to put the undercarriage selection lever back to the down position and once on the runway the undercarriage then collapsed.
Pilot - Sgt W E Quinn RAFVR (1068596).
