I study Civil Engineering. Not only does 0.999...=1, but 0.99=1 and hell, sometimes even 0.9=1.

If you were doing physics, sometimes even 9=1.

the plane takes off the wheels just spin really fast and it probably needs a little more thrust to counteract the friction of the wheels

I am pretty sure it's rotors won't spin with enough shrimp power to make that happen.

No, Zarn you barn, .9999 would not, could not on a treadmill.
.9999 would not could not, in a liquor still.

.9999 cannot do these things, you see
.9999 will not do anything, trust me.

.9999 would not, could not on a train,
.9999 would not, could not, in the rain.

.9999 is not capable, Zarn you barn,
.9999 just can't do it, so darn.

No.

And why not, mr. Venkman?

The plane's thrust does not come from its wheels. Its wheels are free-spinning. Thus, they spin as quickly as the treadmill wants to spin them. They offer little resistance to the engines' thrust.

My only thought in terms of the plane takeoff was if you were to take it to a more realistic conclusion:

If somehow a treadmill could be made to perfectly sync with the speed of the airplane, that would mean it would reach infinite acceleration almost instantaneously, right (as the treadmill is supposed to keep the plane from moving)? And on top of that, the wheels would reach speeds that would be so fast that they would likely explode/meltdown/other violent response, resulting in the airplane smashing into the tarmac. Thus, no takeoff.

Then again, I'm being silly.

The treadmill would not be able to affect the speed of the airplane unless it were able to reach ludicrous speeds at which the backward force caused by the (minimal) wheel friction would match the thrust generated by the plane.

0.9999... does not equal 1, as we all know. Then there must exist x, non-zero, such that 1 = 0.9999... + x

Every real (except 0) has a multiplicative inverse. Let x*x^-1=1. Then 1=0.9999...+x iff x^-1=x0.9999...+1 iff 0.9999... + x = x^2*0.9999... + x iff 0.9999... = x^2*0.9999... iff x^2 = 1 implies x = x^-1 = 1 Therefore 1 = 0.9999... + x iff 1 - x = 0.9999... iff 0 = 0.9999... iff 0/0.9999... = 0.9999... / 0.9999... iff 0 = 1.

Therefore 0 = 1.

QUED.

No, because the plane has a finite limit on the amount of thrust it can put out. The wheels will at most move 2x as fast as the plane's maximum ground speed without air resistance (because with air resistance it would just take off).

Correct me if I'm wrong, but what does the thrust have to do with it? All the plane's thrust has to do is move the plane (and that'll happen, and assuming nothing explodes it will eventually take off, I'm not debating that). I'm suggesting that since the plane has started to move, the treadmill, which is supposed to keep the plane in place by increasing its speed to counteract, would increase its speed infinitely almost instantaneously. By design. Since even if the airplane is moving forward at 1 mile per hour, it's still moving, which means the treadmill isn't "moving fast enough". So it's desperately trying to speed up faster and faster with no effect (because the wheels are freespinning and having no significant effect on the plane moving forward). The result being a treadmill that is going insanely fast, combined with wheels that are also going insanely fast (as it's sitting on the treadmill), before they explode and do horrible things due to the violent forces they'd be put under.
