Several answers and none is quite right.

Commercial and civilian jets all have certified ceilings that vary depending on the weight, balance, of the aircraft and length of the cruise, headwinds, weather, etc.

Most comercial jetliners can cruise at 36-40,000 feet. The Concorde cruised higher, at around 60-62,000 feet.

Additionally, commercial jets usually stick to well-known routes directed by ATC. Spacing for height and distance is variable.

It's a trap!

I think Smartphones are one area where the vertical integration model works well. The fragmentation of Android will diminish it's value to handset makers as customers like you get soured on the issues involved.

At the altitude that the space station is oribiting, there is no atmosphere, and thus no drag per se.

I beg to differ. From SpaceRef.com:

"As a further consequence of ISS attitude, the station's daily orbital decay has been at its lowest (~20 m/day). Orbital decay is a function of atmospheric density at the orbit altitude and the station's cross-sectional ("frontal" or "ram") area, which creates the drag. Depending on attitude, ISS drag area can vary between a low of 390 square meters (where it is currently) and a high of 670 sq.m."

The wings on the thing are just on there to help control the descent and serve as fuel storage.

Shuttle keeps fuel in the wings, hunh? That's a new one. Here I was, all these years, thinking that's what the big orange tank was for.

The wings on the shuttle do not provide lift; the entire shape of the shuttle does. Do a search for "NASA lifting body tests".

"If its on its last mission, and its never going to be relaunched, why bother bringing the thing all the way back, just to be decomissioned?"

Heat, power, air, maintainability. Not to mention that the ISS crew rotating out would need a way to get home and the trip is free.

The ISS was built to store/supply all these things for months at a time. The shuttle was never meant to.

Another factor - drag - shouldn't be discounted either. While the drag at ISS altitude is very tiny, it does exist.

Do you have any idea how much it costs to turn around a shuttle for relaunch? Or to build the infrastructure capable of refurbishing and relaunching it?

Of course not. Anyone with even a passing familiarity of the overhaul each shuttle gets when it reaches the OPF knows that only Governments, Microsoft, and Google have the resources to launch a shuttle.

Boeing and Lockheed (A.k.a. USA) might have a passing chance at operating the shuttle privately, but with the vehicle's inherent limitations, dangers, and cost, no one would be crazy enough to lend them the operating capitol, including their parent companies.

Anytime I want to read pie-in-the-sky conjecture about the space program from people who have little to no idea what they're talking about, I come to Slashdot.
