Speaking of that, were you in on the thread about autopilots and
hijackers? Is it true that autopilots can land airplanes so precisely
that they had to introduce dither so that they didn't wear ruts into
the runways from all of the airplanes landing in the same spot?
Thanks,
Rich
I heard that the F14s now land so accurately on the carriers that the centre
arrester cable has to be replaced often, but the others show no signs of
wear
at least that's what the man in the black helicopter said...

The pilot is graded for every landing and, I believe, needs to maintain
a
certain average if he wants to keep flying. They are surposed to hit
that
cable on a good landing so I'd assume they get pretty good at it
