West Coast, have you ever been to LHR?
I flew in there tonight (no, I am not a pilot by the way) and when I left the aircraft there were SIX sets of lights on the g/s for 9L with a/c landing at the rate of one every 90 seconds. Are you saying that is not busy? As Idunno's facts correctly show, it is by far the busiest airport in Europe.
As crew for a large British airline, every now and then I am able to get hold of a copy of the air safety reports relating to our fleet. I have just counted the number of ATC related incidents in the copy I have to hand, there are more from the USA than from LHR. Considering the amount of company traffic which uses LHR, there are very very few reports of problems caused by their mistakes.
WC, you should really consider the impression you're giving of American flight crew. You're acting more like a jealous child than a professional pilot.
