Would It Take Off?
Discussion
Sorry to turn up late, but I think I can help here.
The original poster was very clever in dropping the question into a car-dominated forum. We car-focussed people automatically think of power and motion being transmitted thought the wheels of a vehicle. But that is not the case with an aircraft.
The engines of an aircraft push it forward regardless of what the wheels and tarmac are doing.
Just because the runway conveyor belt is moving backwards, that does not stop the plane moving forwards through the air. The only effect the conveyor belt has is make the plane's wheels spin faster than normal.
So the plane moves forward and eventually takes off. The only difference from taking off on a normal runway is that the plane's wheels are spinning twice as fast. As long as the wheels can cope with being run at twice the normal speed, it is a normal take off.

Ooh, I hadn't thought of that!
No seriously, that's the right answer as I'm sure the majority of us now recognise. You're late to one hell of a party in this thread!

Congrats, the 'No shit Sherlock' award! (at this stage)

Yes, we informed people have known that all along, but there are a certain few here who are convinced that airplanes put their power out through the tyres, maybe gripping onto clouds, migrating fowl, sky-hooks, the hand of god, whatever, when they are high in the sky.

Regardless of the fact that we know the answer I still think it would make a good Mythbusters story line.
I have this mental image of various trials with baggage conveyors and model planes culminating with Adam and Jamie building a remote controlled Cessna with Buster the crash test dummy in the left hand seat. Then building a huge feck off high speed conveyor belt.
Got to be a classic episode.

Just read all 26 bl00dy pages and to be honest it did take me a while to grasp the fact it would take off. Shame some people got so high and mighty about how clever they are, just because other educated people saw the problem from a different point of view and thus took longer to get their head round it....
Good fun though!

Yes, but what would Kari Byron be doing?

She can fly me preferably NOT by wire anyday. Arf Arf!

As the instigator of the 'catagory system' I would like to remind everyone of my position as 'chief classifications occifer'
..I now hereby resign due to 'the incident with the number 4'

Can't be bothered to read through the million pages before but if that was the case, why don't they have these conveyor belts on Aircraft Carriers, instead they use those Steam thingy's to throw it forward to give it "lift".
So i have to agree with everyone else on that note.
just my 2 pennies worth.

Because it's a totally pointless device that serves absolutely no purpose whatsoever (other than to confuse the terminally befuddled).
