Which is why any KSP multiplayer implementation should avoid letting this happen. As stated here:

Mine's on the mantle over the fireplace. The thing is quite impressive.

Because many of us see the pointlessness of the question and are just having fun, others like to answer questions, and even others just like to be right and can't resist poking their noses into an argument, which the internet makes so very easy.

Yes. Eventual heat death of the universe makes it inevitable.

What if we replace the wheels with treadmills?

Ever tried a Lapsang souchong? It's a tea dried over wood fires, giving it a smokey flavor.

Of course not. The wheels will remain stationary and move forward with the plane. Now, if the belt exerts force on the wheels and the plane remains stationary, then the wheels would spin.

Make a separate clean install of KSP. Make sure it will start/run. Then start copying files from the old install to the new one, but only do it a little bit at a time, checking to make sure it will start and run after each copy. Eventually, you'll get back to a working copy, or figure out what causes it to break. Unfortunately, it can be a time-consuming process.

You seem to have mistyped "/dev/null".

Everyone does. Until their backyard is allocated for hazardous waste storage...

If a plane is on a treadmill, is it still able to spray chemtrails? More importantly: If Paul McCartney was killed trying to take off in a plane on a treadmill and replaced with a reptilian clone, how was there enough jet fuel left to melt the fake pictures of the Apollo program on the holographic moon of the flat, but hollow, earth? Checkmate, aliens! Edit: I would like to sincerely apologize to the Illuminati for leaving them out of this post, as they are truly responsible for everything. Fnord!

I'm just glad my employer doesn't block the forum. Can you imagine if they actually expected me to do my job, instead of surf the internet?!?

It was not uncommon for me to have whatever book I was reading taken away. I usually carried a spare (or two).

Is the plane painted blue and black, or white and gold?

I'd be more worried that the treadmill might fall off the plane and FOD the engine.

But the problem defines that the wheels and treadmill are moving at the same speed. If you allow the wheels to spin faster, the plane takes off, but then you have left the hypothetical world defined by the problem, and you are talking about a different question. Reality: The plane on the treadmill is going to take off. The problem, as defined: Some phantom force holds the plane stationary, and therefore it cannot take off.

Magic or not, there's an unexplained force in the problem as described. If the wheels and the treadmill are always moving at the same speed, the plane must be stationary. If the plane were moving forward, the wheels would be moving faster than the treadmill. If the plane were moving backward, the wheels would be moving slower than the treadmill. Therefore, since the problem states they are moving at the same rate, the plane is stationary. If the plane is stationary, there must be some force counteracting the forward thrust from the engines. This force is not defined in the problem. Perhaps someone tied the plane to a tree behind it with a very strong rope? Perhaps there is a brick wall at the front of the treadmill, preventing the plane from moving forward? Perhaps there's a wizard in front, shouting "You shall not pass!" at the plane? Whatever the reason, the plane is not moving, and therefore will not generate sufficient lift to take off. Once that force is removed, the plane's going to move forward and take off.

Well, yeah. That was the point in bringing up the absurdity and calling it "magic".

But the way the question is defined, the treadmill is always moving at the same speed as the wheels. The wheels, by definition, cannot be moving faster than the belt. Therefore, the plane must be stationary. You've explained exactly why this is not the case, and I understand it. (See here) Therefore, the only way that fits the definition of the question is to ignore the physics and throw in some undefined, nonexistent force. Or, "magic".

But the wheels are always spinning at the speed the treadmill is moving backwards, so they can't actually move forward, therefore the plane can't move forward and gain lift. The way the question is set up requires a number of situations that can't actually exist, and therefore it has no connection to reality. It's an absurdity, therefore the only answer is "magic".

That's the problem, though. Thrust is going to be constantly accelerating the plane from 0 to some positive value (X). The treadmill must then accelerate from whatever speed it's at (call it Y) to X + Y. This brings the plane to a stationary position again. The plane now accelerates to X, and the treadmill must accelerate again to 2X + Y. Then 3X + Y, 4X + Y, etc... The treadmill is going to very quickly end up moving at unrealistic speeds, and will need to continue to accelerate to hold the plane stationary. Physics can't help, so it has to be magic.

You're assuming the wheels will fail before the treadmill. Absurd questions require absurd answers.

Well, we've got a plane on a treadmill acted upon by magic forces, and a treadmill that can accelerate past the speed of light, powered by more energy than the universe could ever produce... I'd say it's fair to assume a magic plane, as well. Short version: No, the plane can't take off, because no such system can exist as described.

And then, the engines would accelerate the plane. Which would accelerate the wheels, and the treadmill would then accelerate, and then the plane would be held stationary, so it would then accelerate due to thrust, which would accelerate the wheels, which would accelerate the treadmill to hold the plane stationary, the thrust from the engines would then accelerate the plane, which would... loop ad infinitum, to the point at which the wheels and treadmill are now moving at infinite speed (and still accelerating), physics has long since failed, and the plane is now airborne and not airborne at the very same time, because we can just ignore physics and common sense. Again, the problem asserts a situation that cannot ever occur, and the plane is only prevented from flying by the absurd ever-accelerating treadmill. No one has yet demonstrated what force counteracts thrust to keep the plane stationary, beyond the magic wheel/treadmill equality.
