Your Blackness Sickates Me

Update...

So I do some searching last night and come across this;

MythBusters special - I HAVE to see this! They are going to do this in FULL SCALE.

Now - the pilot says (near the end) "if I match my speed exactly the same speed forward as its (treadmill belt) going backwards and there is no air over the wings I should sit there like a brick..."

At this point I think I am not totally crazy!

So I go and read this which sheds more light on the subject... The wheels on a plane are free wheeling (like the article says) unlike a car which are driven to provide forward movement. :lightcomeson: !!!

Now I get it!

Ed Zachary! The plane takes off!

And with that, I am too busy to deal with these slow loading forums. Adios!

You can have an airplane flying into a head wind of 500 mph and not move relative to the ground. Its the speed of air over the wings that create lift.

Ever see a seagull floating in air or even moving backwards against the wind?

This is scary stuff. There is a reason they are only at 99.9 percent. If they made it to 100 it would form a black hole and destroy the planet.

The plane does not take off unless it has airspeed. Unless it has forward motion or a whole lot of wind, no takeoff.

This was killing me! I got fixated on the wheels on the ground...

I helped with our aviation merit badge counselor for our Boy Scout Troop - my buddy (helo pilot) spent about 4 hours going over instruments, navigation, lift, engine theory (combustible and turbine)... man - I had to learn a lot before I could even talk about it!

I need to call him and see if I can get him on it - but he probably has already heard it...

Agreed. The crux of the question was if it was on a conveyor belt going the opposite way and matched the speed of the wheels, would the plane take off.

Answer is unequivocally YES. The jet engines push the aircraft forward to lift off speed. The wheels are nothing more than legs to hold up the plane. They have nothing to do with propulsion, forward or backward motion. They can spin to pieces regardless how fast the conveyor goes.

Read Cle's last link. Splains it very well.
