Not terribly common, but they do happen.garf12 said:are go arounds very common on commericial flights? On the probably 300 flights I have been on I have never had a go around.
I saw two in twenty minutes one Sunday night recently when down at PHL waiting to pick up my mother-in-law. First one was a 737 on 27R who was ordered to go around when the aircraft ahead of him missed his turnoff, the second was pilot initiated when he lacked faith in the controllers judgement about spacing for near simultaneous arrivals on the intersecting runways 27R & 35.
