The oldest Lanc Pilot I am aware of was Wg Cdr Vashon James 'Pop' Wheeler D.F.C. and Bar, M.C. and Bar, Order of St Stanislaus (Russia) RAF, CO of 207 Sqn. Killed in a Lancaster near Frankfurt on 23rd March 1944. Age 46.
He was mentioned in Peter Townsends 'Duel of Eagles' autobio,I think when they first met they were calling each other 'sir' , P T was at least a sqdn ldr by then but was confused by 'pops' grey hair,pop was a pilot officer(or maybe F/O) in those days.
Sad he didnt make it.
Pop was a rifle brigade officer in WW1(underage !) ,learned to fly between the wars,volunteered for RAF(lied about his age again!!) and was a night fighter pilot on Hurris,Havocs,Beaus and Mossies.After being grounded by Fighter Command he volunteered for Bombers but was unlucky and his Lanc was hit by flak within a few weeks of being made OC 207 sqdn.
