I have a rule of two. If two things go wrong in any area to do with the flight before I take off I don't take off, because someone or something is trying to tell me something. I'm a fairly pragmatic person but I'm willing to accept that there are more things in heaven and earth etc.
Great stories by the way chaps, keep them coming. I have no twilight zone stories from actually piloting but I did tell my wife when we boarded a commercial flight once that something was going to go wrong. Don't know why I said it and have never said it before or since but we were struck by lightning on take off and had to dump fuel and return.
