For Talkdownman, I have actually practiced go-arounds in gliders at hilltop sites such as Long Mynd where it is possible to land and roll safely over the edge to become airborne again, given the right conditions. I have also done go-arounds in motor-gliders, Strikemasters and Varsities while doing GCA and ILS calibrations on the latter. I have also been fortunate enough to fly in the jump seat on several occasions during my career as an avionics engineer.
Having made several hundred flights on passenger aircraft, I can only recall having gone around twice, both times at Valencia, the previous occasion being for a change of runway direction following severe turbulence on the initial approach.
