Danny, now that you mention it, it is rather curious how determined he seems not to even touch the controls. Any pilot would know that his mentor would be following through (as indeed he is told) and that there was no risk involved. Of course, he also knew that his efforts would be on video for posterity and probably didn't want it to show him making a complete Horlicks...

I'm sure you have already, but if you haven't heard the story of his service, do ask him. I don't think I've ever felt so humble (Synopsis: 114 combat ops....impaled into his seat after a crash landing in Norfolk, his crew outside shouting "get a move on you lazy b****rd!". Stomach reconstruction, finishes his 4th tour as a rear gunner because his stomach muscles weren't strong enough for the rudder; pops off a Ju88. In between ops 114 and 115-120, becomes the road manager for Glenn Miller's band. Amazing.)
As for the squadron badge, your eyes are better than mine, for I cannot say that I can make anything much out of his lapel badge at all. If indeed it is a fox mask, then that was 12 Squadron (bombers) flying Lancasters out of Wickenby as shown here:-

We have many skilled researchers here on PPRuNe, unlike me. I'm sure that one will be along soon...
Edited to add that what this story does highlight is the excellent work done by Project Propeller, now in its 15th year of getting WW2 veteren aircrew airborne again. Respect! :-
