I had a fault middle of last year when I'd landed at Sandown.
In the time-honoured fashion, I knocked on the door of the nearest friendly looking hangar to ask if I could borrow the required tools to put it right. When I was invited in, I was rather surprised to see two Spitfires and a Hurricane under construction - a very impressive sight. I can think of worse ways to make your living, although the cashflow must be a little erratic.
(Plus they were very friendly, and helped get me in the air again, refusing any attempt to pay for the time and couple of bits I'd scrounged).
