I agree that the second programme was the more interesting, although I got a bit lost with the boffin from Qinetiq who seemed to prove that dropping a bomb made a splash and his rather laboured explanation of how backspin would keep the bomb against the dam wall.
I was pleased to see that some of the crew had reservations about the fidelity of the exercise, one thought it might be "silly" but they certainly seemed to learn quite a bit from the exercise.
One small point; considering the effort put in to accurately recreating the event, they slipped in a shot of a Manchester when they were talking about 617 departing Scampton at tree top height on the night of the raid.
