Let's put an F15 on the magical conveyor, shall we? And draw a free-body diagram of it for us engineering types:

Thrust Force Ft = 50,000 lbs
Aerodynamic resistance Fa=? but it is negligable compared to 50k lbs for our purposes = 0
Mass M = 32,000lbm

F = MA

I would like somebody to tell me how a conveyor, no matter how magical, can hold back that jet by touching those little tiny freewheeling wheels.
