<< i`ve never seen one "circle" the airport>>
Usually when the press report aircraft "circling" an airport they mean holding and this often occurs away from the airport.
However, in this case the aeroplane almost certainly flew a "circuit", i.e turn after the go-around then a turn downwind, then a turn to base leg and back on to final approach. No low fuel, no "smoke" (where on earth did that come from?), no excitement, no big deal, just a bog-standard go-around and everyone lived happily ever after.
