Jesus Andy, you're a shit opening this can of worms again!

Speaking as an aerodynamicist, of course it will fly. Those of you who think it won't, shut up now. You're stupid and making fools of yourselves.

Prove it then.

[Vultch]

As above... lets see the proof

[Albannach]

Well done Andy I tried hard not to get involved but the urge to stop stupidity took over.

Jesus Andy, you're a shit opening this can of worms again!

Sometimes, I just can't help it...

[Apache]

Prove what?

Andy's a shit? Is proof necessary?

[Andy Pandy]

Whats all this got to with the price of eggs in Tesco,s

[Predictable Bob]

Thank feck I'm right again !

[TonyN]

It never gets old.

[Predictable Bob]

I'm still unsure about whether it's peoples inability to read English or if they're just plain stupid ...

Which Andy?

Throw your wisdom out there..

OK, here is a thought experiment/conundrum for all the clever-clogs on here.

You have an airplane sat on a huge conveyor belt. The conveyor belt is computer controlled such that its speed is always the same as that of the aircraft - only backwards; i.e. If the aircraft is moving forwards at 10mph, then the conveyor will move backwards at 10mph.

Will the aircraft be able to take off?

Assumptions:
1. The aircraft is otherwise normally capable of flying just fine, and the pilot is normally capable of flying this aircraft just fine.
2. The conveyor belt runway is more than long enough that if the belt didn't move the aircraft would have ample room to achieve take-off. There are no obstructions that would affect a normal take-off.
3. The runway is at sea level, the air is still, and the conditions are perfect.
4. All measured speeds are relative to a fixed point.

OK, so, will it fly or not? Please explain your answers if possible.

Yes it will be able to take off, the belt can do what ever it likes because it only matching the air crafts speed the air craft is still moving forward as stated in your question so wing lift will be present ect so on and so on.

Prove it.

Prove it.

I dont have to the question states the aircraft is moving forward thus a air stream over the wings, it does say eg 10mph but doeasnt say anymore but with the rt brothers it was at 8mph and they had wing lift so im presuming at a minimum of 10mph with full flaps youd get it. emm
For some reason i felt a need to answer this but i think im gonna regret it

Either the aircraft is in fact moving forward at take-off speed, in which case it will take off - the conveyor belt is irrelevant in that instance - it is just spinning the wheels at double their usual take-off rotation speed. Or the aircraft is moving at less than its take-off speed because of some mysterious effect (probably aliens, or some astonishingly effective brakes on some very grippy wheels) which prevent whatever the method of thrust is from moving the aircraft relative to the fixed point. In which case it won't. The latter is wholly improbable (except the aliens, which definitely exist, hence all the government cover-ups).
So it will take off.
