Air Traffic Visualization

Likes:  watching the stream of eastbound transatlantic traffic in the U.S. East Coast's evening and the return spritz in Europe's afternoon; the way New Zealand and Hawaii stick out; also, it's just pretty to look at...
Dislikes:  the fact that domestic air travel (U.S., E.U., and Japan) is so tied to the diurnal cycle.  I guess peaking just irks the transportation planner in me.  I don't think red-eyes are anyone's favorite, but look at all that unused right-of-way! ;-)
