I thought Alan was on 54 Sqn at the time. At least, I think that's what he told me at a 54 Sqn reunion some 25 yrs ago - mind you, it was a very alchoholic weekend...... I also seem to remember we had a painting of the event in the crewroom.
Can any current 54 Sqn or 1 Sqn members help on this, it should be somewhere in the Squadron archives.
Thanks,
A
