Once and for f*cking all....

Confused. What does whhel drag have to do with lift?
It's like a kite. If you took the propeller off a plane and tied a rope to it, put the flaps up and towed it till you reached the correct speed to generat lift it would take off and fly. You of course would have to keep that speed or it would crash. But lift needs to be generated by wind. not my a turbine or propeller.

the only thing that would hinder the plane's forward motion is the drag caused by the wheels on the belt. The thrust would overcome that.

anyone want to make bets on the outcome?

To reiterate: Shut the fuck up.

Everybody shut the fuck up. Seriously. Wait for December 15th.

The drag of the wheels on the belt isn't enough to overpower the thrust of the jets.

who says the belt speed always matches the plane speed?

Good GOD I hate you all.

Wait for the show.

Here is the original thread of whiners and nuts. God that shit was annoying.

[delatlanta1281]

Wait... The turbines move the plane forward but the wind over the wings is what creates lift. If the conveyerbelt itself is "stationary" and the plane isn't actually moving forward, where is the wind to generate the lift?
Just saying.

Either way, we can all watch the plane go nowhere while reminding ourselves how cute Kari is, and how annoying Grant is.

It does not matter how the plane is propelled. If the belt is always matching the wheel speed, the plane cannot move forward. With that said, I don't see how they're going to pull this one off with a jet/rocket.

Well, if the plane is taking off under its own power, it doesn't matter how fast [or slow] the conveyor belt is going. If the plane is placed on a belt and the speed is cranked up, then no.

MythBusters
Air Plane Hour

Jamie and Adam take wing to test if a person with no flight training can safely land an airplane and if a plane can take off from a conveyor belt speeding in the opposite direction. Tory, Grant, and Kari jump on some Hollywood-inspired skydiving myths.
