Jesus wasn't white.

Pipe down, Sonny!

Buwahahahahahaha! I heart Preston. Can I play too?

So you're trying to tell us you're coming out of the closet? I did not expect that...

Cs = ? Oc = ?

I was just wondering this today. How about variable temp. as well? My shimp was burnt all to hell.

Ok, so you're saying that the plane WILL NOT be pulled rearward, at all, by the treadmill? Next. Your pool theory. You're saying to swim OVER the treadmill. In relation to your analogy, the plane isn't flying OVER the ground. The wheels are, in fact, touching the ground. If you're swimming over the treadmill and swim low enough so your stomach touches it, you will be pulled backwards, no matter how slight. And Nick, you don't even want to get started on spelling errors... That is like the 3rd word I have ever spelled incorrectly on CR. Don't read too deep into that.

*sigh*....You people just don't get it. Let's put it this way. Let's say that you start moving the treadmill in reverse at a slowly increasing speed. Now, you turn on the engines to provide just enough thrust to slow the planes rearward travel, bringing it's overall airspeed to 0. You continue doing this until the treadmill is going 11ty billion mph in reverse, and the plane is going 11ty billion mph forward. This still brings your airspeed to 0!!!. I'm going back to my model car theory. Most you you nay sayers must also believe that a model car will stay in the same place indefinitely. I don't care how massive the plane is, it will eventually begin to move backwards, regardless of wheel spin. I'm not saying that the plane is going to hammerdown on the throttle, outrun the treadmill and take off. I'm saying the two will be matching speeds. If it takes 30 years of accelerating to compensate for the ineria, then so be it.

And there are a shit ton of dumb people in that 10 page thread. The only way it could magically take off would be if it had an LSx motor in it. Other than that, it's staying on the ground.

This goes back to the model car explaination. Given enough time, the plane could be pulled backwards on the treadmill at a high rate of speed. As Ken said, this is a HYPOTHETICAL situation.

I'm calling Mythbusters right now.

If you could somehow take potential energy out of the equation, then yes, it would stay stationary, relative to everything but the moving ground. You're factoring in slope and potential energy into your answer. Obviously, the car would pickup speed on a downward slope. If the ground is stuck at 10mph moving backwards, while the car is accelerating PAST 10mph moving forwards, then of course the car is going to move. If you could somehow keep the car from accelerating due to potential energy (i.e level ground) then you take that variable out of the equation.

"The treadmill begins moving backwards to match the planes speed. (forward speed is inferred here)" Nick, you're reading into the question waaaay too much. Take it for what it says.

In reality, could the plane out accelerate the treadmill's rearward pull, factoring in ineria? Sure it could. But that's not what the riddle is saying. We could also strap a Saturn 5 rocket to it and get it to fly, but the riddle isn't saying that either. What it's saying is, if you matched the planes forward speed, with the treadmill's rearward speed, would it take off?

Ding ding ding! We have a winner.

Ok. My next argument. Let's say you put some functioning wings on the SVX. Now, you drive it down the highway (where the road isn't moving) and at 88mph, it goes airborne. Now, because it is propelled by the wheels, it's obviously going to lose airspeed (<- keyword) when those wheels lose contact with the ground, and fall back down. The only difference between the plane's thrust and the car's thrust, is that the plane can move itself through the air, even after the wheels have left the ground, whereas the car can not. In our riddle, the plane has not left the ground, so it essentially behaves as the car would. Now, take the same car, and put it on a treadmill that is going 88mph, backwards. Drive the car forward at 88mph. Is it going to fly? Nope. And neither will the plane.

They will after the ineria equals out. Remember, the treadmill is matching the speed of the plane. Let's say that the plane is increasing it's speed by 1mph, every hour, that should be more than enough time for the wheels to catch up with the planes acceleration. Think of it this way. If you put a model car on at treadmill, and turn on the treadmill, does the model car sit there spinning it's wheels in the same spot indefinitely? Sure, at first, it will spin it's wheels. But they will eventually stop, and the car will be moving backwards at the same rate that the treadmill is. Same goes for the plane.

You're forgetting one thing: friction. As long as the plane is ON the ground, it WILL be rolling backwards. Turn off the engines, but leave the treadmill on...the planes gonna roll backwards. If the plane is moving forward at 300mph, and the treadmill is pulling it backwards at 300mph, you have an air speed of 0(300-300). 0 airspeed = planes not going anywhere. ground speed relative to treadmill = 600mph ground speed relative to the ground outside of the treadmill = 0 airspeed = 0 next argument...

What if you're too drunk to read the display?

"Two men dead after fatal crash" ...as opposed to two men alive after fatal crash? Sorry, just caught my attention. Anyways, Sorry to hear this. Sounds like it could have been prevented though.

Ok, first off, it amazes me the amount of stupidity on that site. Here's the argument/riddle: A plane is setting ON a treadmill (on it's wheels). There is no wind. The plane using it's jet engines, begins to accelerate forward. The treadmill begins moving backwards to match the planes speed. If they both keep accelerating, will the plane eventually take off? /riddle. Ok. It's overwhelming the amount of people on that site that believe that it WILL take off. You guys really should peak around on there to read some of the stupid reasons people give as to why it WILL take off. Now, my reason for it NOT taking off: In theory, the plane will have X amount of ground speed, however, ground speed doesn't create lift under the wings. You would need airflow over the wings to create lift. In order have airflow over the wings, you either have to have a headwind, or airspeed. As long as the plane is ON the treadmill, it will have no airspeed. No airspeed = no airflow over the wings = no lift. Now, post up your opinions on this. And if you have time, and want to read something entertaining, mosey on over to OT and read up.

Sam. Please take down the pictures of my house. I don't want people to know where I live...

Will you be my mentor?

yea, I saw this on the news. It said he was traveling at a high rate of speed, and also that the car he hit was going the wrong way down the street. Totally demolished both car and bike though. They said he was a new rider. Go figure. BTW, it looked like a 600rr to me.

Charger, Challenger...All the same to me. Both ugly.
