Is your middle name lucky?
Well, my wife does not think so, as four aircraft I have formally flight tested have crashed fatally sometime following my approval of modifications. Each crash was found to be pilot error, not the plane or the mod. In addition, three other pilots I have flight tested with, have died flying other aircraft. Two pilot error, one I'm very suspicious is an inadequate aircraft design.
It gives one lots to think about during a flight, in trying to ward off the effects of complacency, or pilot error - I simply have too much experience to have any excuse for an accident in a GA aircraft now! Then, add to that, some new thing stuck on, or dangling from, the plane which I'm test flying, and I'm being even more careful!
A saying on a wall mural in town reads: "Luck favours the prepared". Words I live by.....
