"Sawing" noise during approach/landing?
Coming back into Heathrow from Stuttgart last night I heard what I can only describe as a noise like someone using a manual saw during the final stages of the flight (final approach and on the ground, mostly on the ground). It's not a noise I've heard before.
One of the pilots emerged from the cockpit just as I was about to leave the plane and confirmed this was not normal.
Any thoughts greatly appreciated.
