I had the pleasure of working for a month or so with Mac McCormack overhauling WS/55 G-AODP in the summer of 1968, getting it ready for a ferry flight to Warri.
Super guy, he lived down the road from me in Radstock Way, Merstham.
He was earmarked to be the engineer to fly on the ferry flight to Nigeria, but had a few problems at home, which did not allow him to do so.
Being the type of guy he was, he went to Mack Macaskill and recommended me to do the flight instead.....the rest is history.
I do hope he is still around, I shall be watching this thread with interest.
