Just checked my little orange HMSO index book, Back in the 80s would phone Mrs Wright X5218 to arrange transport to Farnborough. She would call you back with timings for pick up at the Control Tower and return flights. The Chieften would pitch up and you get on without a word being exchanged. Unfortunately in a way this was after the Ah! de Havilland, Devon.
At the time I was designing some special signals kit for use on Snoopy and the M25 was being built. The drive was so tiresome.
I would get a lift over from Huntingdon with my Dad who worked in the Hangars, spend a bit of time looking over the strange modifications going on. Back in time for a cup of tea and early stack.
