• There is NO wind.
• An airplane is placed on a giant conveyer belt.
• The conveyer belt is connected to to a computer and sensor system,
• such that the conveyer belt will turn the exact same speed as the
• airplane but in the opposite direction that the airplane is traveling.
•• Will the airplane be able to takeoff?

Under it's own propulsion the answer is yes, from the conveyor belt, alone, the answer is no. Propulsion will generate forward movement regardless of the conveyor speed, forward movement means movement of air over the wings creating a negative pressure zone over the wings thus producing lift. Did I get it right? (sinister grin)

Yes, but the wheel bearings are gonna get pretty hot.  edit: the tires might also explode from spinning too fast. They probably would not explode at the same time thus creating a drag on one side which would then cause the airplane to veer off of the conveyer belt and explode in a giant ball of flame amongst the spectators.

I'm no engineer, but if it's not physically moving forward, there would be no air movement around the wings, therefore no lift?
You old fart, you did it again!

Just remember it all comes down to Thermal Osmoses.

I was going to say I saw this on Mythbusters but could not remember the outcome.

The plane took off, Danny, but it was under it's on power.

Over on the TFF this subject has perhaps generated more post total than any other subject ever discussed on the TFP.
Who’d a thunk?
