In about 6 years of intensive business flying as pax - 3 go-arounds, no rejected take offs, and 1 lightning strike (on approach at Heathrow).
The most 'interesting' though was a 'nearly' go around at Schiphol during severe weather in June 2007. The approach was the worse I ever experienced literally being thrown around in my seat. Outside was very murky with several lightning flashes seen. Then I heard the engines go full-power and I thought 'please don't go back up into this mess!' but within a second we popped out of cloud and went on to make an uneventful landing.
It took me several flights before I could properly relax again, and I wish they would just divert in conditions like that.
