I always wanted to find a clip of that Champagne task. All I can remember was at the end, Keith did a very low level celebratory turn that made me go a bit pale at the time - Maybe the blade tips weren't as close to the ground as I remember, but either way, the banked turn was an even greater bit of flying than the task itself.
Not to mention landing on the submarine during the Treasure Hunt series. Oh, Anneka in that jump-suit. Its all flooding back !
