Practising for Churchills funeral - I had thought the original picture was in the Aylesbury local newspaper, but I see their photographer (in white jacket) on the right side bank further back
on reviewing the site I spotted a familiar face, the Drill Corporal standing on the bank to the left of the picture is Jock bailie form B Flight 3 Wing - Bill M
Sqn Ldr Sid Sills second from left in the second rank, with Fg Off 'Jankers' Crawford at the other end nearest to the Old Workshops 'Smokers Lounge' - Frank Bowron
