Anyway, you can see from the picture in post 123 that the aircraft is partially off the paved surface and from the FR24 data released, it seems to have stopped at approx 40 degree to the centreline. That's no criticism of the crew by the way; they did a magnificent job of stopping and getting everyone out.
Standard procedure at BA is to turn the aircraft downwind so the flames are blown away from the aircraft if at all possible.
