I watched both programmes last night and expected the Beeb one with the McGregor brothers to be better, but then realised it was a repeat (and was also shortened from the original I think).
Good to see Sir David doing this (and not making it all about him) being that he is a RIAT ambassador and all that (visiting over many years in his R44 as I recall)
Tenuous link - I also remember being part of the team that helped to send the Trotters Reliant Robin to the sandpit from Brize post-GW1!
