plane on a treadmill won't fly.
great example right here.......
get a kite string out 5 feet of string run a tread mill and see if it flies!!
All that is necessary to create lift is to turn a flow of air. An aerodynamic, curved airfoil will turn a flow. But so will a simple flat plate, if it is inclined to the flow. The fuselage of an airplane will also generate lift if it is inclined to the flow. For that matter, an automobile body also turns the flow through which it moves, generating a lift force. Lift is a big problem for NASCAR racing machines and race cars now include spoilers on the roof to kill lift in a spin. Any physical body moving through a fluid can create lift if it produces a net turning of the flow.
simple terms if the plane doesn't actualy move it don't fly jet engines push the aircraft forward through the air to create lift a propeller pulls the aircraft through the air to create lift your legs pull the kite through the air.
staionar objects don't move hence they don't fly; running on a treadmill = stationary.
take a few years of aeronautical engineering then debate over it or break 15,000 hours flying an actual aircraft.
now if you get the kite to fly I will personally give you my firebird.
