Pilot’s Narrow Escape.—
Pilot Officer "J." Martin, of the Royal Air Force Camp Digby, narrowly escaped death on Monday when the aeroplane he was piloting crashed
into a stone wall near the camp. It is thought that Martin stalled to avoid
another machine, and that the aeroplane went into a spin. The machine was damaged, and Martin was extricated
with fractured thigh and other thigh and other injuries. Improvised splints
were made from parts of the machine'

The under mentioned are all posted to No.2 Flying Training School, Digby, with effect from 11.7.31 - one of whom, was: A. C. Martin.
