I only ever got involved with one once during my time. I had to fly a guy up to Bremen to catch his flight. We were hammering along as fast as the Lynx would go, and it was obvious that we were going to be late. I called up Approach and asked them to hold the flight. There was a pregnant pause and they came back and asked if we had a VIP on board.
I looked back at the L/Cpl infantryman in the back and replied, "Yes". We landed next to the aircraft and he was met by the mover and straight up the steps.
