Why airplanes taxi

So, logically, spacecraft in the frictionless environment of outer space
should immediately accelerate to the speed of light.

No, it still takes energy to accelerate a mass, even in a frictionless
environment.

But the original post said that aircraft taxi because their wheels reduce
friction. No mention of energy or force. So if the statement is true,
movement results from a lack of friction alone, so zero friction should
produce infinite speed (or lightspeed if one allows the speed of light as an
absolute upper limit).

However, space (especially near space) is not frictionless.

Nor does friction produce acceleration. QED.

Your post about airplanes flying stated that it was because of the
wings, no mention of energy or force, moron!

What does that have to do with taxiing?

You tell me, you posed the question.

What object could ever be accelerated to the speed of light?

On 2/6/2008 6:04 PM Mxsmanic ignored two million years of human
evolution to write:

No, I did not.

Actually, you tedious lying idiot, you did. But since you employ your
usual dishonest method of editing the context out of posts to which you
reply, who can tell - unless, of course, one simply looks at the
posts in this thread?

So, would having wheels reduce the friction in near space?
