Way back in the 1988, me and a mate walked along the bottom of the North face of Ben Nevis. We heard a helicopter flying around and out the clouds came a big yellow Sea King helicopter. It landed near us and all of a sudden a mountain rescue guy and two other guys, one with a tv camera and the other with a sound boom ran up to me and my mate. The mountain rescue asked us If we had seen two guys in some problems around the North Tower. We had not. The three guys ran back to the helicopter and flew off. We only found out later that It was for a documentary series called Rescue. It was a bit of a surreal moment...
