Hmmmmmm. The only hold I ever had was between valley and Chivenor. I was forced to spend 2 weeks standing next to a Gnat mock up (in No 1s) answering questions from Joe Public. The good bit? The mock up was in the basement of John Lewis in Bristol ------- in the perfume and make-up department!!!!!
Never had such an interesting set of evening dates made during the day!!
(Those were the days when being a pilot ensured interest from the ladies)
