The Scout I underslung from Cadenas to Airport Camp in Belize had the doors off. It was a real sod to fly, swinging and bucking above 70 knots.
As the Puma was variable speed/constant fuel consumption I didn't have enough fuel to go direct so I dropped it off at an airstrip and my escorting Puma with the rotor blades, REME party etc looked after it.
I was night when I came back for it. I could only just see what was going on through the fog of mossies.
