I can't wait for the 12th so this thread will die.

Back when I had my 911 turbo, I put that up as a bet. NOBODY took it.

What concerns me is that almost half of IA.com are not the brightest. This isn't a hard question, people.

Here is another one:

If a plane is on an indefinitely slippery surface, will it take off? What if that slippery surface is moving? Will it still take off?

Same concept...because the component responsible for propelling the plane forward is not in contact with the surface it's moving along. It'd be the same as if the plane was hovering.

sounds cool, ill watch

This just in...

The episode, which airs in December, finds Savage and Hyneman tackling a question baffling everyone from bloggers to pilots: If a plane is traveling at takeoff speed on a conveyor belt, and that conveyor belt is matching the speed in reverse, can the plane take off?

``We put the plane on a quarter-mile conveyor belt and tested it out,'' says Savage about the experiment using a pilot and his Ultralight plane. ``I won't tell you what the outcome was, but the pilot and his entire flight club got it wrong.''

I'm going to bet that they all thought that it "wouldn't" take off. Ahahahha

lol this is gonna be the highest rated mythbusters ever. There are gonna be so many ppl watchin this sh*t.

[Wurm]

no that it wont take off ruiner. In theory it should take off but i dont trust human error

Human error? Listen, if someone TRULY knows that it should take off (which it will), then Mythbusters will not get it wrong. I assure you on this. However, good luck!

My answer is that IF the plane creates enough thrust to overcome the conveyor and get the plane moving forward, then it should fly. IF the conveyor is at a constant speed, then it should be easier for the plane to overcome with enough thrust. IF the conveyor adjusts speed up in accordance to the amount of thrust, then the plane can't move forward and therefore it won't be able to fly.


Too many "IF's", but that's my take on it.

Are we gonna do wings and beer somewhere so the winners can gloat?

If you tied a rope to the front of the ultralight and stood on either side of the conveyor belt your hand alone could easily overcome the conveyor with virtually no effort

If that's so, then it's going to take off.

[Psycho]

I think the plane is going to move forward on the treadmill just like it would on regular tarmac. The plane isn't going to sit still just because the wheels are moving backward.

[Ruiner]

A. Today is the day, bitches!

B. I created a nice drawing for some of you who might be confused about the rotation of the wheels... The wheels spin the same way! How is that going to hold the plane back?

[bigdare23]

I really sat down for 30mins using my Mechanic Engineering knowledge to explain why it would take off.

But my post just got kicked to the side


{shakes head} I give up.

lol, i realize this. Trust me, growing up as a pilot's son, the last thing i need is a lesson about aerodynamics.

here's how the actual problem is worded:

Suppose a plane is on a runway that acts as a conveyer belt. The conveyor belt is as long as a typical runway. The plane moves in one direction, while the conveyer moves in the opposite direction at the same speed as the plane. The wheels of the plane are free-rolling. Will the plane be able to take off?

Notice it says that the conveyor belt is the same size as a typical runway. SO, we know that if the plane were to move forward, there would be plenty of room for it to take off.

Now, i realize that you guys are saying the wheels will roll as the conveyor belt passes by. Well i'm not sure what kind of planes you guys are talking about, but i've never seen one powered by its wheels lol, so the wheels don't matter.

In that case, whether its a moving conveyor belt or a stationary runway, the jet's engines (or the plane's props) will push the plane forward at normal speed as if it were on a regular runway, causing it to get air under its wings.

kthxbye

quoted so i can say i told ya so

I TOLD YA SO.

[Ruiner]

1.5hrs til it all goes down! Granted, they'll probably save this one for the end of the ****ing show.

9pm on Discovery, fewls! Mythbusters bitches!

[Julio]

About ****ing time.

[Ruiner]

About ****ing time.

You are damn right. I hope to see 43 people proven wrong...

[Ruiner]

~30 ****ing minutes...oh fawk yes!

[speedminded]

Why didn't anyone bet me?!

[Johnny Chimpo]

WTF its not in the show.

[Ruiner]

WTF its not in the show.

Just 'cause it isn't in the preview...

[Jaimecbr900]

It doesn't look like it's going to be on tonight's show afterall. I bet I could land that plane though.....

[Nittanys1]

i was wondering the same thing...maybe they will throw a quick answer out there...

[speedminded]

WTF! There is no way they can do it in 9 minutes can they?!

[On_Her_Face]

very very doubtful

[Jimmy B]

make a new poll, can they doo it in 9 min?


lol.... i was looking forward to it too

[On_Her_Face]

lol

[Nittanys1]

myth busted...........

[Jimmy B]

oh well.. mabye next time 43+ people will be proven wrong

[Nittanys1]

lol...when will that be?

[speedminded]

Somebody's gonna fly a plane into the discovery channel headquarters.

[Jaimecbr900]

That took off from a long long conveyor belt.....

[Jimmy B]

That took off from a long long conveyor belt.....

jamie, lol +1 hahaah

[mocha latte cupcake]

so since i didn't waste the time watching this did it take off yes or no?
