(...) Last I checked, it's faster to fly west than east, since you'd be flying into the planetary rotation instead of overtaking it. Also, you can't judge the size of a country very accurately by board-to-debark times, since many airlines pad those (...) (20 years ago, 12-Jul-04, to lugnet.off-topic.debate)

(...) Basic physics says that if you spin the world in one direction, the air will (generally) spin in the other direction (counter-rotation, equal/opposite reaction and such), which should carry you even faster into the rotation and fight you even (...)

(...) Does this apply to driving, as well? If so, I may have found a new excuse for being late to work. But a more serious question: How big a factor *is* planetary rotation vis a vis commercial jet travel? I would have thought that, because flights (...)

(...) I think the issue is the jet stream. It moves eastward somewhat faster than the ground, so going east you have a tailwind, and going west you have a headwind. Unfortunately for you, the mountains in PA aren't high enough for this to make you (...) (20 years ago, 13-Jul-04, to lugnet.off-topic.geek)

I must admit I have never checked, so I can't even say "last I checked", but since Long Jumpers don't slaver at setting world records on a west facing runway let me be the first official doubter.

(...) I'll buy that, except that the original claim seemed to be that the rotation itself was the factor, not the jetstream. Admittedly, I may have misunderstood the framing of the problem: perhaps the question of east/west travel already assumed (...) (20 years ago, 14-Jul-04, to lugnet.off-topic.geek)
