Question...

[Bulldoggie]

No matter how fast a conveyor travelled it would NOT stop the thrust from pushing the plane forward, unless it could excede the max. speed of the wheels or the wheels had brakes applied.
The trust would still push the plane forward, just as the thrust on a Harrier pointed downward is able to lift even if you took your hypothical conveyor and made it vertical and put the wheels of a harrier on it's nose the conveyor would only spin the wheel. the harrier would still climb because of it's thrust.

I don't think you could offend anyone by being correct. In theory, if the aircrafts wheels were frictionless then the conveyor would have absolutly no affect on the planes ability to run up the runway and take off (Inertia would keep the aircraft still (with engines off) regardless of conveyor speed). I was assuming in this case that the wheels did have friction and thus the conveyor would be able to exert force on the aircraft. Is the question asking whether or not the aircraft could take of standing still (conveyor speed increasing to keep the aircraft still)? or if the aircraft could take off with the conveyor matching the wheel speed (obviously yes, but in its regular distance)?

A bicycle is on a treadmill and the treadmill runs at the same (but opposite rate) as the bicycle's speed (same situation as a runner on a treadmill, but riding a bike). Is the bike easy to ride?

Yea, the gyro-effect of the wheels keeps it balanced and since there's no drag, yea easier me thinks. The only opposing forces would be from the bike parts bearings/chain/tires low on air

Thanks for the link -my head was starting to ache.

yeah after I posted that I gave it some more thought because the solution to the "riddle" was a bit too simplistic.

It would be a different story if the wheels powered the forward thrust or it was a car

OK... upon rereading my post, I realized it was ambiguously worded, so I wanted to make sure.
