I well remember Spencer Flack, albeit over a rather short period.
I flew a PA31 out of Elstree in the mid of 1973, never quite got the hang of the Elstree VASI! and spent an even shorter time flying the B58 out of Leavesdon. After that the call of the Middle East, (Bahrain and other Gulf stations), got me.
Actually was allowed to drive his brand new white Jag to his house from the pub once, well, they had just returned his Rolls to him and even he couldn't drive them both! Was amazed at his huge display of model aeroplanes that he kept at his house.
Around the end of 1973 we had a fuel crises on the horizon, Spence just drove to his local garage and asked how much they had in the premium tank, when they told him he wrote them a cheque and then put his own padlock on the tank, fuel crisis solved!
Many of you will remember the Three Horseshoes Pub in Letchmore Heath, Eddie Dexter was the landlord then, a really great man. Still soldiering on and now living in Lincolnshire.
