Interesting to note the name given at the beginning of the commentary - it'll be familiar to many. As for shutting down halfway through a display to carry out a check - that's exactly what the CH53G crew did at Middle Wallop during their role demo (1986) after the stinger dug a furrow. No loss of face, no heckling from the pilots' tents, just a realisation that when things go rwong you do something about it.
Back to the vid anyone notice the big clump of mud falling to the ground (with about 2':56" left to run) as the aircraft passed through the overhead?
Oh, and anyone who thinks a heli display can't be interesting (2s in, perhaps) should try and get access to a vid of Charlie Zimmerman's Bo105 display. That'll be the one that won the Greenham Common mil aerobatic display trophy in 1977...
