Really irritated air traffic controllers, and possible discipline from
the FAA. I believe the 250-knot limit is just to keep traffic flow
smooth, as lots of planes of wildly different performance levels are
flying about. I think it's also a U.S.-only restriction. I seem to
recall that Concorde would really like to fly a bit faster to save
fuel, but slows down to be a good citizen.
