Can a Plane on a Treadmill Take Off?

Look..... for all you people that think that the plane will take off.
Whats the point in having CAT Launching systems on aircraft carriers
priced at billions of dollars a piece... they could just pop down to
wallmart and buy a treadmill and the aircraft will not need to use any
runway what so ever........

No, they couldn't. Or, put another way, a scenario in which an airplane
launching from a carrier could remain stationary on a treadmill would rely
not on the treadmill, but on the presence of a suitable headwind. Of
course, in the presence of a suitable headwind, the treadmill is not needed.
But that's the whole point to this trick question: the treadmill is a red
herring.

DONT BE STUPID....

You should think a little harder before throwing the "stupid" word around.

IT CANNOT BE DONE !!! IF IT CAN BE THEN SOME CLEVER BUGGER 50 YEARS AGO
WOULD OF DONE IT BY NOW..

plus, has anyone thought what will happen to that aircaraft if i does
manage to generate enough lift..... ITS GOING TO HAVE NO AIRSPEED,
stall and fall out of the sky like a brick.

The airplane can't generate lift without airspeed. It's absurd to claim
that it would have "no airspeed". If it has enough lift to fly, then by
definition it has airspeed.

Simple physics lads...

Yes, it is. But the physics only give you the correct answer if you apply
them correctly.
