For those of you who still don't buy it: please explain to me how the treadmill is holding back a freewheeling tire on an airplane that is trying to move forward.

Maybe the pilot is holding the brakes.

Maybe it's in R

Here's the flaw in your logic, "no air is moving across the wing to give it lift" the source of the Thrust is pushing agains the AIR behind it, which means that it will push forward regardless of what the wheels do. it could be 400 miles an hour it wouldn't matter, it will still move the plane, The reason that the navy couldn't use it is because the airplane would still take of normally and require the same length of runway, the runway would just be moving under the tires. I took the position you are taking for quite some time this afternoon, I finally asked an engineer friend of mine who set me strait.

I called my Dad- 30 yrs working on jet engines and engineer school at Weber st.- You guys are right, but the conveyor would have to be as long as the runway normally needed to launch the plane. I see the light!

But, if the conveyor was only say 60ft. long the plane would accelerate off of the conveyor and then take off normally.

I read to page 4 and gave up. I think what we are missin here is not " if a plane can take off from a conveyor belt" but wheter or not one can take off from a conveyor belt that is counter acting the amount thrust the plane is making. Yes a plane can take off from a conveyor belt. But if it is not moving because of a conveyor belt counteracting the thrust of the plane through the wheels, then no it can not because there is no air moving over the wing. If some one has already said this, oh well.

I'm a developer, not a Physicist. I was adapting a linear logic basis against a real problem, happens to me all the time. and actually --- He does work for NASA - How'de you know? - you're watching me aren't you?

so you have a car right, and it's traveling at 60 mph into a 60 mph headwind. does the car move? and if so, could you blow it up with the r16 fazer featured in Nerd-destroyer 2 for xbox 360 or would you need the Vulcan molecule destroyer from episode c32f1234 of Star Trek next generation...

I think my 2 year old nephew understands why the plane would take off.

start with this one:
How much wood would a wood chuck chuck if a wood chuck could chuck wood.

That should keep you busy for a while

Wow. So are we all finally agreed on this, the plane flies? If not, :rofl: :rofl: :rofl: @ you! :p


Okay, I just read the question to my wife, who has abosolutely zero aviation or science background. It took her about 3 seconds to say "yes, the plane takes off". The speed of the runway is 100% irrelevent.

Did you actually figure it out, put any thought into it at all, or did YOU just read the posts and pic one that looked good. A better question is why do I know someone from NASA and why would that person actually talk to me about a post on some forum somewhere?

50-50 shot, better odds then vegas, yes-no! I'll play those odds anyday.

Well, before I even saw the question on OT, my friend Erik asked me this same question and I answered it correctly in under 2 seconds. It's pretty simple.
