s this scientifically impossible?, it can “NEVER” hit the ground…can it?

Are you on crack?

I have no idea what is happening here

How do you think a sea plane takes off, lets say that the sea plane wants to take off to the north, and the sea is pushing it south, the plane just glides across the water and takes off.

Well you have to take off into wind to generate lift. Same as landing, you land into wind so to use it as a kind of brake.

The plane is clearly moving forward in the mythbusters episode, this gave it enough airflow across the wings for it to take off. If it's position was stationary in relation to the ground, it would stay still.

That's correct but why would a tread mill keep it stationery?

The engines provide forward thrust. Once the plane has gained enough speed on the runway, the wings will provide positive lift and it will take off.

Dude, we have given you links to *prove* to you that it takes off.

If you want to keep telling us no it won't then great be my guest, the bottom line is we have given evidence that it does in fact take off.

When you're in the gym on a treadmill aren't you stationary? Isn't that the point of a treadmill? LOL

I have a feeling it is going to be a pointless debate, where someone refuses to accept evidence.

?

You are missing the point, a human provides power by its legs. Consider that the same as a car on a treadmill.

A plane does *NOT* power anything by its wheels, what so ever.

Is this a case of LOLasim18 O.o

That evidence is bs. The "treadmill" wasn't fit for purpose and the plane was moving forward.

When I'm on the treadmill in the gym, I don't have 2 engines providing thrust for me.

Again how is this the same as an aircraft on a treadmill. The only thing touching the tread mill in a plane is the wheels. which are unpowered and free rolling.

really go back to school.

Sweet jesus, watch the episode and stop being such a poor little fella.

They also did it small scale, and had a small treadmill, the plane also took off.

No matter how fast your treadmill turns you will never get enough friction through the bearings in the free spinning wheels to even come close to the power of the engines, so the plane will always move (but with its wheels going backwards) and take off.

It's more like if you were on a treadmill and you were wearing rollerskates and you strapped a jet engine to your back, what would happen? Would you stay still, or would you in fact fly into the wall?

Lets test it on him and find out!

Tefal · 3 Sep 2009 at 18:11

a good testof this is to get yourself a toy car with free spinning wheels take it to a gym place it on a tread mill and then push it slowly forwards.

even though the wheels are going backwards you (the engines) can still move it forwards.

Of course, but how would a treadmill keep the aircraft stationary?

That's the point then. A treadmill's purpose is to keep you stationary, while you're trying to move forward.

If the treadmill kept the plane's ground speed at 0, then it could never take off.

This is precisely the example I gave about a year ago

No because it isn't slowing down. It travels 500 feet, then travels another 500 feet. Then hits the ground. If it was alive, it's now dead.

In a nutshell, yes.
