Neptunus Rex:
Too right BOAC. I wondered the same myself, almost three minutes at their likely groundspeed, one can only imagine that there was some huge distraction in that cockpit. The hackles on my neck would have been raised long before one minute, let alone more.
They would have been in compliance with the procedure flying at an IAS of as high as 205 knots. Do you have any idea what Airbus would recommend as an IAS for downwind on a circle-to-land?
