We haven't got this one cracked yet!
Aircraft - no positive id but it certainly looks like an 825 cab. Clicker's info that 91 was attached to Hermes in Nov 92 could be true but these pictures are typical Falklands shots and Hermes returned home in Jul 82 and didn't go south again.
Crew - I am also not convinced that we are looking at H. 825's P2s came from the 706 AFT course that had just finished, supplemented by 2 from 819. If I recall correctly the following were S/Lts:
Chris Greaves, Brian Evans, Dave Wolstenhome, Paul Lyall - from 706.
Pete Eldridge and Martin Rayner - from 819.
If this is an 825 crew, and there is support for John Skinner in the LHS, I would go for Pete Eldridge.
