This is amazing.

I love how, at the end, the dogs on the inside put their paws on the screen door
-"Hey, Sophia, what about us? Get us out of here!"

New Rule: Don't bother locking the zipper on your luggage. Locking a zipper is like locking a screen door; it's only going to keep courteous criminals out.

I am "Scale the Screen Door Kat!"

They use that plexi glass... the same stuff my screen door was made out of for my house. They used to use that glass, now i think its a Pyrex type of glass. Either way i saw the game that changed the way glass is done in the arena, it was a game where this guy got checked into the unpadded glass between the Sin Pin and the wall glass, he cut his face from chin to the top of his forehead, some 47 stitches.

If any one remembers the game let me know because I saw it, but cant remember the player.

thats kind of what I'm talking about below.

Smart cat. I wish i had a video of my old dogs teaming up on the back door. They used to open it all the time, the screen door and the main door.

I'd slam her like the screen door on a submarine.

The building was designed to have a fully loaded 707 crash into it - that was the largest plane at the time. I believe that the building probably could sustain multiple impacts of jetliners because this structure is like the mosquito netting on your screen door - this intense grid - and the jet plane is just a pencil puncturing that screen netting. It really does nothing to that screen netting.

That was from Frank DeMartini, the on-site construction manager of the WTC. It's all in the video. Unfortunately we'll never know whether or not he was surprised by the collapse because he was in the North Tower helping people to evacuate when it fell.

You're right to point out, of course, that a plane travelling at 500mph has much more kinetic energy than one flying at 200mph (a little over 5 times as much, in fact). It's a little disingenuous to focus on this, however - it implies that the towers could resist a hit from the slower moving plane, but not the faster moving one, as if the slower plane would be stopped dead in its tracks! You're obviously a smart guy, Krupo, so I'm not going to suggest that this is what you believe - I'm just pointing out that kinetic energy isn't as important a factor as you might think.
