Errrmmmmm ... The entire thread it would appearNo airspeed = no take-off with conventional aircraft. What have I missed?
Having read most of the conveyor saga and taking the OP back to basic principles, how does the aircraft move forward to create airspeed if the conveyor is cancelling out the ground speed?
The airspeed of the aircraft isn't measured in relation to the belt its measured in relation to a fixed point not on the belt ... Once you've grasped this one you'll have seen the light and be on your way to take off velocityThis of course can be done but not without increasing the speed of the item in relation to the belt.

doesn't work for an aircraft. If the aircraft was moving through the air at even 1mph, the wheels would be rotating at 1mph so the conveyor would move at 1mph the other way. But the aircraft is still moving through space at 1mph so the wheels are turning at 2mph (1mph movement plus 1 mh conveyor). So the conveyor moves at 2mph. But the plane is moving forward at 1mph so the wheels are turning at 3mph. So the conveyor move at 3mph to counteract it. But the plane is moving at 1mph through space so the wheels are turning at 4mph. So the conveyor moves at 4mph. But the plane is moving through space at 1mph so the wheels are tuning at 5mph.... etc
If an aircraft on this conveyor has a lift off speed of 180mph, then the wheels will turn at twice that speed - 360mph. That's all there is to it.

Jet thrust. Or, if you prefer, by use of its propeller(s).No airspeed = no take-off with conventional aircraft. What have I missed?
