LOL nice job sully, rheittorated what I said but with a pwnage way of explaining it.

A jet will not take off, A prop plane will. Jet can't make it's own wind for lift. A prop plane can. Just kidding.

Just think, no matter how fast them wheels are spinning, to the rest of the world it's not moving. So you have no wind for lift.

How about this for an experiment. Take your stupid skateboard (I couldn't see the video.) put a paper airplane on it. Put it on the treadmill. Hold the back of the board so that it does not move but the wheels spin. (This is the jet thrust.) Crank that baby up... And you will have a paper airplane on a skateboard.

Shado, how is a spinning treadmill jet thrust? There is nothing in your scenario propelling the skateboard forward.

FYI, I know you were kidding in your first paragraph about a prop vs. a jet, but I just want to get it out in the open, lift is not created by the force of jets or the wind from a prop, it is created by the flow of air over the wings caused by forward motion of the plane or an air mass moving around the plane. In theory, given a strong enough headwind a plane can "hover" off the ground. This is why it is preferable to takeoff into the wind and land with it (Point 5).

Although it is true the reversing speed "runway" will make it more difficult to takeoff, it will not hinder it completely.

Am I the only one who noticed that the fan in the video was facing the wrong direction?

An airplanes propellers pull air while a fan blows air. With how you had it set up you should have pulled the paper from the other side.

Sorry but pride is right. My father was a pilot in the air force. Questioned him about it and he gave the exact same reason that pride is telling you. I allready knew he was right but I wanted to get some closure on it.

lol.

i don't really understand some of this stuff, but i agree with pride.

not because of his scientific reasoning, but because of a thought that just ocurred to me.
if a jet could take off like that, why woulndn't they use it on aircraft carriers or somthing? it would take up less space right?

argh, you guys really dug this up. Well, I will argue my point more if I have to. The plane will take off. It would take the same amount maybe a little more space to take off that it would on a normal runway, but it would take off.

Pride is wrong on this one. The treadmill exerts no force on the plane, which he stated at the beginning saying that the treadmill matches the plane speed. A plane has no drive on the wheels so the speed of the wheels is irrelevant. The plane (jet or prop doesn't matter) will be pushed forward because it exerts it's force on the air. I think a better question would be this pride. A plane is flying into a 100 mph wind at 110 mph. How fast does the plane appear to be moving from the ground??

OMG...Talk about a thread resurection from the dead. This hot debate is like 3 months old.

Anyways, lets let it R.I.P. but in anycase *cough* The plan would fly

Mythbusters are testing this one on the show. I'll let you google the results.

Looks like it has been resurrected once before...

Billabond1 · « **Reply #58 on:** January 30, 2008, 09:18:14 PM »

I just watched the episode. All I have to say is that I was right.

sully! · « **Reply #59 on:** January 30, 2008, 10:05:34 PM »

Arghhh, you all beat me to this resurrection!

All I have to say is "Na na na na boo boo! I was right and you were wrong!"
