The engines are considered indestructible, where are they ?

It's in my garage.

It's amazing, how nobody thought about looking for the plane in the beginning.

Censoring kike fag,

The plane vaporized.

And F4 is considerably different from a 757 jetliner. You also see the wings of the F4 slice through that concrete wall. There are no wing impacts what-so-ever on the Pentagon.

There are no wing impacts what-so-ever on the Pentagon

Cruise missile confirmed.

Actually, the wing tips continue in a straight line because they were a little wider than the barrier. The wings themselves were destroyed.

Basically this.

Most of it is in really small pieces, inside the building. We went over this yesterday. Planes are made of pretty flimsy materials and are built to withstand certain forces. Buildings are not one of those forces.

There's also debris, but most of it is inside the building in very, very small pieces. This is pretty basic physics, actually. Yes, it was really smashed with a plane.

Then how did said "flimsy pieces " go through all the different layers/rings of the Pentagon??

E=MC2.

I'd like to see your explanation if you can be bothered to link it.

Either way, that one in PA was shot down.

Energy equals mass times speed squared.

Ever seen the aftermath of a tornado? A piece of hay can go through a tree. Force is a measure we use in physics. See the thread from the day before and someone actually shows real footage of what happens to planes when they hit shit at 500 MPH. It's counterintuitive but they dissipate rapidly as they are not designed for crushing forces at speed.

I have seen the image of hay in a tree.

Physics never burned a witch; doesn't sound like very much fun.

An airplane is made of very light and thin materials. It worries about things like torque or containing kinetic energy while allowing expansion and flexibility.

Now, the walls of the Pentagon are like five feet thick. It's made from concrete and designed to withstand kinetic energy (as well as structural load).

Energy is a factor of speed and mass by the way - that's what E=MC 2 means. E - energy M - mass - C speed of light in a vacuum.

So, planes are massive. It smashed into something with even more energy - namely a building. See, the building also contains energy - 'cause it's mass. If anything, I'm more surprised that it did that much damage and that there was that much refuse left. Yesterday, someone showed a video of an F-5 hitting a concrete barrier at 500 MPH (on purpose) and the only things left where the wing tips 'cause they missed the barrier.

Basically, when that much force (energy) is put into the system (the plane) it's going to not be able to contain it - even individual molecules are going to be split. Even single atoms are going to split (no, not an atomic bomb) and their energy is going to be released. That's what the smoke and fire was - that's energy escaping. Energy, like matter, isn't created or destroyed - it's transfered.

Seriously, I'm surprised there was any refuse left. If you look at other images, there's still some chunks of plane kicking around.

heygeorge

Ok, that sounds like fun.

:D

Good morning! You are up early, no?

TheBuddha

I am up early. I went to bed early and then went and had coffee with the neighbors and helped milk for a little while. Then, I decided I was cold and came home. I also wanted eggs and milk for breakfast for the missus. I'm going to make her pancakes in about 4 hours and feed her breakfast in bed. (I do this often.)

Bahahhah

Right? But I'm crazy for thinking buildings can free fall from jet fuel, and planes can vapourize on impact.
