Thanks Buckley!!
I'm sticking my neck out here saying I don't think it can take off - guess i'll find the answer there
No. Because aircrafts lift is generated by the movement of air over the wings.
In order to generate positive lift and take-off there needs to be enough airflow over the wings in order for the angle of attack to be allowed to increase and therefore create the positive lift.
Basically the aircraft aint going anywhere without actual movement over the ground not just how fast the wheels are turning. Without actual forward movement through the air forcing it over the wings there is no capacity to generate lift.
No airflow = No go. 8)
Sorry if that sounded too physics geekish
but I am a student pilot of 3 years 
instructors got the stuff imprinted on my brain now.
:x

yes
the drive isn't through the wheels (as in a car), it's through the air.
So regardless of how slow or fast the conveyor belt moves it's still gonna be getting propelled forward through the air, the wheels'll just be spinning faster...

1000% Agreed. This plane is going no where (fast) and I hope it's not the one I get on to get to Ibiza this summer!!!
only kidding
What about if you put 50 birds in a van and they were all in mid air would the van weigh any more

are the birds fit?

once again IT DOESN'T MATTER IF ITS ON A CONVEYOR BELT OR NOT.
it'll move forwards regardless therefore it'll take off....
It moves through the air because it's drives forward through the air, the wheels are nothing to do with it's forward motion... (hence the fact that it can fly) think about it...

Sorry, Matt.. MB's got it right.
The forward motion isn't caused by the wheels, as Matt noted. It's caused by the engines.
BUT, when the plane is still on the ground, the engines just make it roll until it's going fast enough for the wind to create lift under the wings. Thus, if this conveyor is keeping up with the wheel's speed, then it never gets enough lift and there's no takeoff!

I agree with the 'it's not going anywhere' group, as the centre of gravity of the plane would be on the conveyor belt - it would be supporting the plane. The only time this would cease being the case is if it was going fast enough to get lift, which it never will, as the conveyor belt cancels out any forward momentum.
