Long range glider towing
A bit of 'drift' but close to the subject was the towing of (just from memory this bit) 3 'poss 4' Horsa gliders from RAF Portreath in Cornwall to a strip in North Africa (Vis Biscay) one ditched due to tow break but the others arrived. That's a long way in mostly enemy held skies. No doubt the full story available somewhere. Tugs poss Halifax.
