It has happened before where aircraft have been assigned to a positioning flight and then changed for whatever reason.
I canceled a positioning flight (Not a BA 744 flight!) last year where the aircraft was changed at the last minute and the aircraft which was assigned the positioning flight now had a full tank of fuel as it was due to fly elsewhere with passengers.
This meant it was out of trim with no pax on board.
There was no way of getting the fuel off the plane so the flight was canceled.
So it could be that something like that happened to the BA 744 but they chose to dump the fuel instead of canceling the flight, who knows!!
