Rotary dit on...
Dartmoor, Sarops on, at night, very dark, lots of mist and stuff, pre nvg, pre GPS, 20-30 feet agl, 'kin dangerous.
Trying to nav out the cargo door with a right angle torch and a 50 thou, to a casualty.
My SAR diver was front left, hatch open, responding to my geographical inputs.
What I did not know; the a/c Captain’s first name was the same as my big, bezzy oppo, diver, mate.
Unaware of first name thing. I was telling/asking/giving directions up gulleys/ valleys and stuff, on a big best mate format.
On RTB, pulled to one side by RHS and told to “always call me Sir, in future”.
