I was thinking about this the other day. As a pax who flies reasonably frequently (usually 15-20 times p.a) I have experienced a go around three times over the last 5 years.
First one approaching Bergamo in a 757, interestingly this aircraft had external cameras that were switched to show the outside world on the pax screens. I saw the boundary fence of the airfield and next thing we were up and away. PA announcement from FD said that they could not raise the airport on the radio so prudently went around.
Both other times were aircraft slow to vacate, once at MAN and once at LTN.
It was instantly recognisable because of the power increase.
I have never flown on any other aircraft that had the external cameras, if I recall correctly it was a Brittannia 757 but wouldn't like to bet on it.
