The VC10's pax cabin for Ex Medicine Man flights to/from Calgary was a sight to behold, with almost all spare space filled with soldiers' personal kit. One year when aircraft were slipping through Brize outbound from Gutersloh, two headcounts with the clicker showed a passenger missing. To resolve things, pax were offloaded and a quick parade and count were held on the ramp - all present and correct. It then emerged that one chap in a window seat had got back on board and immediately burrowed under a pile of mukluks etc for a kip and completely vanished from sight.
