Hi there,
I am absolutely sure it wasn't reverse thrust as i could see into the engine inlets and heard the engine shutdown
It seemed to be the starboard engine. I was watching this in Heathrow's terminal 1 where there is a seating area where you can watch the aircraft taxi past at extremely close proximity, the only downside of this area is that it is located adjacent to the smoker's area
