Coff,
like most of the VSO he almost certainly did not do a full Herc OCU. He may have done a Herc famil prior to taking up his appointment. I am sure someone who was there at the time can fill us in on the details, but probably RHS at least for the T/O and landing.
On a slight thread drift there is the story of a non qualified AOC who tried to insist on doing the take off in a VC 10 at Muharraq. Perhaps Beags can fill in the details.
