I can't remember the airline but was on a charter flight some years ago from Corfu to Gatwick. On finals into Gatwick and about to cross the motorway we started to climb out. Immediately the PIC came on the PA and said despite being given permission to land by the b*gg*rs in ATC (his words not mine), there was another aircraft on the runway. He continued, "I'll just give you a circular tour of West and East Sussex and we'll try again." No panic from the pax, just a few giggles and my wife's hand tightened a few more notches around my knee. Thank goodness she is no longer a nervous passenger as in the current climate I doubt I would ever get her in the air.
