While the GPS may give them more accuracy, this was being done long
before the GPS became available.

But now they live long enough to amaze the rest of us

Seriously though, I'm sure the accuracy of the GPS and the cute little
moving map makes this much more tempting, and thus, common.

Yeah, but GPS direct flight also takes advantage of the wide open sky and
hopefully keeps all of us off the same airway.
