Heathrow Runway Operations - Question
I thought that the operation of runways at Heathrow was switched at regular intervals between take-off and landing, to allow a degree of peace to LHR neighbours.
However, whilst waiting in a line for take-off from the northern runway yesterday, was surprised to see a Virgin 747 landing just after 9am, in the middle of a stream of "take-off" aircraft. Other 747s landing normally on Southern runway, at this time.
Got me idly wondering whether this is normal. Anyone? Apologies if silly question, but then it is Friday afternoon!
