It seems sad that the capability wasn't available in UK and that they had to bring a Puma over from Norway.
Is there a video of this on t'internet?
I was on duty at Gatwick when the Sea King lifted the A/C plant (I think that is what was lifted!) onto the top of the brand new ATC Tower in the mid 80's. That was very impressive to watch, as I am sure this recent effort was as well.
