I've had two aborted landings in several hundred flights.
Cubana at London Gatwick, off centre and missed the runway so did a go-round.
Air France, Paris CDG did a go-round don't know why.
I've also been on an Japan Airlines 747-400 at Heathrow which aborted a takeoff about 15 seconds into the takeoff roll. "Ahhh.
Air traffic control say nogo. We try again". That is a bit of a fright because the plane shudders to a halt with the engines still screaming.
I've also had an aborted takeoff on a light aircraft, that was because there was a 4 wheel drive vehicle driving up the bit of beach we were using for a runway.
