The Mitchell above (N4852V) was the camera ship for the Battle of Britain film (filmed 1968 or 69).

The 1967 (I think) schedule for foreign charters was:
Friday early evening: Condor Flug Viscount 800 (they had 4)
Saturday early morning: Balair DC-6
Sunday afternoon: 2 x Sudflug DC-7s
Not sure who the charterer was in any of these cases, but I guess that in those days, the flights were from/to the country of origin.
