I don't know much about physics, so if this is a stupid question forgive me.

Why aren't space shuttles drill shaped?

If the inner rocket and outer rocket had something in between so that the outside spun and the inner rocket stayed stable.

There wouldn't be any extra energy needed, because the air resistance would cause the spin.

Or if the thrusters were slightly angled to cause spin? – kishfoo Nov 30 '11 at 4:03
The energy required to bang a hole in wood would be greater than the energy needed to drill one? – kishfoo Nov 30 '11 at 4:04
Because it wouldn't help in any way; drills are drill-shaped to transport the crunched matter out from the hole, not to get a thrust deeper. – mbq♦ Nov 30 '11 at 9:51
hmmmm.......... – kishfoo Nov 30 '11 at 11:52
@mbq ""drills are drill-shaped to transport the crunched matter out from the hole, "" Not all drills! Look for drills used to make gun barrels or the drills used for oil wells, or the center drills for wood. – Georg Nov 30 '11 at 15:47
