Agreed. I was at Brize in the 70's when I was very glad of the medics, you were just as essential as everybody else. Talking of the Varsity my logbook also tells me we flogged around for 4hours plus and the bubble sextant was a total nightmare. Couldn't keep it still and could see at least a million stars. How on earth anyone shot the right one was a poser. The periscopic sextant changed all that. If the star wasnt between the two red dots you had got your sums wrong. Throughly enjoyed the aircraft though great memories.
