We don't need a computer sim. Mythbusters did it full scale. How much better can you get then that?

Clearly that's not proving it to some people since they're still arguing that it won't work. :idk:
That's an argument here for you... if you can't be right arguing it your way, change the specifications of the experiment so that you sound right anyway. :lol:

We can run the Mythbusters test again. Use a prop plane. If they feel so confident that it won't move they can stand in front of it.

The list of people I'd toss in front of a moving prop-driven plane gets longer every day... don't tempt me.
We could do the same with a jet, but my dad has instilled in me too much respect for the gas turbine to want to see someone get sucked into it.

With the economy and fuel prices it would be irresponsible to use a jet engine. Plus with the prop plane we can have an Aston Powers roller moment.

The answer is no, planes take off based on lift (Bernoulli effect) which requires high pressure under the wings and low pressure above. The shape of the wings make this happen as air passes over them. If the plane is stationary and the tires are spinning and the engine is running it will just burn fuel and wear out the tires.

The plane moves forward. It doesn't stay stationary.

If the plane were stationary, the question might as well be, "Can planes take off when they're cemented to the ground in a hangar.".

LOL, I'm remembering a different version, I guess. I remember hearing that the treadmill exactly matches the plane's wheel speed, which is the part that's impossible (and usually f's people up).

If people need (yet another) analogy to make this make sense, pretend you're talking about your kid's Hot Wheels car on a treadmill with your hand holding it in place. Can you imagine anything that you could do to that treadmill to make it impossible for your hand to move that little car forward? No. The plane is the same, except it's the Hand of God moving the plane. :lol:

The treadmill could quadruple the wheel speed indefinitely until a rip in interdimensional fabric occured. The plane would still move forward relative to the ground and take off.

Until that singularity opened and the back end was sucked into the time rift where the passengers slated to die were removed to help save the human race in the future where pollution and genetic manipulation has made us incapable of reproducing.
