Once they get over 30,000 feet, they get propelled by the solar wind (essentially free energy).

All of the naked ladies hang out above 30000 feet.

Really? You figured that out all by yourself? You must be like a genius or something. Maybe even an Oregon post doc.
If all airplanes flew at low attitude, there wouldn't any mile-high clubs.
In addition to the "less air resistance" there is also something called a "jet stream" which they chase. I can't believe no one has mentioned this yet.
Do you guys think that an airplane could take off from a giant treadmill?

It would take too long to press the little up arrow 300 times.
How big is the treadmill?
As a recreational pilot I can tell you it all has to do with air resistance. It's kind of the same concept of guys sprint faster at higher altitudes. It also has to do with flight patterns, the higher up you go the more you can space things and reduce the likely hood of collision with airplanes, mountains and buildings. Also the differnce it would make is very small. Take a 3000 mile flight. Every three thousand feet of alitutde increase increases the flight by 0.02%. That means even if you fly at ground level instead of FL 300 (30000 ft) you shortened the trip by just 0.2%

One mile AGL is still low altitude.

Thanks, Mr. Party-Pooper.
