I would be most grateful if anyone can shed light on what Hedley Eric Grey was doing with 601 Squadron RAF, while serving with them at Tangmere, from 27 July to 10 December 1940. Presumably he was ground crew of some description, but would like to find out more...

While Hedley Grey later qualified as a pilot, that was in 1941 and not with 601 Squadron RAF.

Any insight appreciated!
