Will the plane take off? v. Mythbusters!!! (VIDEO on Page 38)

maybe the question should read "the conveyor will match the speed of the plane to make the plane stationary and then the conveyor will maintain that speed....at this point could the plane accelerate and take off?"

b/c to me the question says the conveyor will match the speed of the plane (it doesnt say the speed matching will ever cease), so if the plane begins to pull away faster so will the conveyor, and as the video proves if both the plane and the conveyor are at the same speed there aint **** happening.

See, you don't understand... See that bolded part? You are incorrect. The plane and the treadmill ARE NOT the same speed. The plane is not moving while the treadmill is. If the plane is stationary, it has ZERO air speed. Don't think of a plane like a car. It has AIR SPEED...

If the plane is not moving, it has ZERO speed. Thus, if the treadmill is moving and the plane isn't, they ARE NOT matching. LISTEN to what the guy says in the video....just listen.

in that case how do you match the "land speed" of the conveyor to the "air speed" of the plane itself....its like comparing apples and oranges....i see the physics of it, i mean hell fire, when it overcomes the marginal friction it takes off...thats plain as day to a monkey in africa....

They are making it simple on Mythbusters, you agree that an airplane has a minimum speed it needs to to gain enough lift to take off and achieve flight correct? Say that speed is 50mph, they will be pulling the "conveyor belt" a constant 50mph with the truck in one direction. The airplane engine will be propelling the airplane in the opposite direction of the truck from 0-50mph which means at take off speed the truck and the plane will be moving away from each other at 100mph. In relation to the ground the airplane will be moving at 50mph and in relation to the conveyor belt it will be moving at 100. The speed of the plane plus the speed of the conveyor belt equals the speed the wheels are rotating.

If I had the means, and if it were legal, I would love to be every one of you that the airplane is going to take off. Can't, though ... being the rule of law type of guy that I am. All I can say is that you're going to be mighty embarrassed when Mythbusters runs their solution at the end of the month.

In a sense, this is rather dismaying. What I'm seeing here is the result of government education. So many people out there sending emails who apparently don't have the ability to think rationally ... to visualize a problem, think it through, and come up with a logical solution.

If you ppl can't noodle out this rather simple problem, please do me a favor and stay away from the polls on election day. You just don't have what it takes.

Quote from Neal Boortz

I like Boortz most of the time.


The longer I thought about it, the more I convinced myself that it was going to take off. I don't think I ever voted, but that's what I would vote for now. :goodjob:

Mach1DrmGrl, I made this thread. Of course it will take off. I was just trying to disprove the guy that made the statement about the treadmill moving but the plane not...yet they would have the same speed.

ahh Boortz

yeah Boortz

ONLY 6 DAYS left

Imma laugh so f'n hard when they dont show it LOLOL

Lol at the idiots who still dont believe it will work. They are the same people that think a boat wont sink in hot water. LOLOL

ahahaha agreed! but they better! so that forums all over the world with government educated people that cannont process this concept of free rolling wheels can finally quit having this debate

The ENTIRE episode is dedicated to it. They'll show it.

But will snakes on a plane on a treadmill take off?
http://i253.photobucket.com/albums/h...atreadmill.jpg

The wheels have nothing to do with the plane taking off. the props will just pull the plane forward. the wheels will turn fast enough for the plane to move forward fast enough for it to get enough lift to take off. it would have to be a loooong ass tread mill because the plane has to have a runway to take off, not just a treadmill as long as the plane, becasue then it would run right off of it.

the only way it can take off is if it is moving forward fast enough to get lift. or if it has a huge wind source, but then you wouldn't even need a tread mill.

Correct, correct, and correct.

This Wednesday will separate the men from the boys. :) The plane takes off.

lolol, someone voted on the poll...it gets bumped everytime and marked unread when they do. It took me months to figure that one out but it was years ago :tongue:

that right there sums it off, whoever said it isn't propelled by the wheels is an idiot, of course it isn't propelled by the wheels, it needs lift hence why the plane needs to be MOVING forward if the plane is stationary due to the treadmill matching its speed then there's no lift to make the plane take off

case solved

So you're saying it won't take off?

Talk about a contradiction...

Read the bolded part...if the plane is stationary, then it has ZERO speed, right? Thus, if the plane has ZERO speed and the treadmill is matching it....what is the speed of the treadmill?

With that said, what you need to understand is that the treadmill CANNOT stop the plane from going forward. Are you familiar with the term "red herring"? The treadmill is a red herring that is meant to confuse you when in reality, it has no true effect on the plane.

no chance in hell that will even possibly work.


the only reason a plane takes off is wind, not whether the wheels are turning.

err negative, the only reason planes take off is lift. Lift that is created by forward motion of the plane. The plane propels itself forward using thrust by pulling itself through air or forcing the air behind it, depending if it's a jet or propellor driven plane. What's going on with the wheels and what the wheels are touching does not matter one bit.

exactly! it would stop a car because the wheels are what pushes the vehicle forward, but a plane's props are what pushes it forward. its hard to explain.

yeah, but it was hard.

OMFG I still cant believe some people are this dumb. Goto how stuff works.com look up how an airplane engine works. Look how it creates THRUST. Then look how the thrust works. Then you will see that the ground traveling in the opposite direction under wheels which free-spin and have no power too then which are there for only comfort and durability of the plane has no effect on wether the plane can or can not take off.

what time does it come on? I wanted to go to the mythbusters meet, but i have a 1080p HDTV at home i can watch it on thats alot closer

this forcing of air is also known as wind.

moving air= wind.

wind is what is needed to create thrust.

huh?! You mean AIR is needed to create thrust...propellors don't work in a vacuum.

Actually, the result of thrust is wind, but in reality, you get LIFT because of a pressure difference between the top and bottom of a wing's surface.

With that said, the plane WILL have forward movement on the treadmill thus causing lift. Got it?

I have 65" of HDTV at home that I just can't pass up. This is going to be great. I'm DVR'ing it as well, so maybe I can convert it to video later on.

9pm bitches! Oh yes...some of you ****s are about to be proven wrong.
