UGH

depressing

Where the hell is everyone?
 
2002-02-23 10:37:01 PM  
given time (and the fact there was a building in the way) this would probably be true..
 
2002-02-23 10:46:56 PM  
too bad it DIDN'T.

Studies show that both planes were traveling well over the federal limits for altitudes below 10,000 feet, The Times said.

Gee...no shiat?

Since the Federal limits are written with the presumption that you DON'T want to ram into any buildings?
Man, that's about as idiotic as saying that a person who committed suicide by downing the whole bottle of sleeping pills "exceeded the maximum recommended dose".

speed kills

Anyone else notice how these guys pretty much said "If you wanna make a building collapse faster, hit the lower floors and hit em at higher speeds." Great advice guys. While you're tell us this, why don't you just start printing your findings all over the middle-east. Dumbshiats.

No really?! What kind of idiot wrote that. I mean...what the hell OF COURSE they're not gona follow the damn federal limits for speed below 10,000 feet. I mean...jeeze...

Don't be opposed to the spread of knowledge, Deef. Be opposed to people having the means to use that knowledge for harm.

Unfortunately, the plane was not travelling fast enough to activate the fluz capacitor and thus go back to the future.

By the way I don't mean any disrespect just thought it was kind of stupid how it's worded in that article. It's like whoever wrote that was thinking there was a chance they were gona check the federal reg's for speed's at that altitude and follow them...no what I mean.

Anyhow...

Nevermind the fact that it's simple farking physics. Dumbass.

AAAAAAAAAAAAAAAAAAAAAHAHAHAHAHA!

I shouldn't be laughing about something like that, but damn, that was funny.

Man, it's been six months and just the sight of the pictures makes it feel like it was yesterday. What an indelible impression that day made.
 
2002-02-23 11:48:16 PM  
Does this really matter?
 
2002-02-24 12:02:57 AM  
Have they writen any tickets for exceeding the federal speed limit yet?
 
2002-02-24 12:06:30 AM  
Does this really matter?

Well, I'm sure that Boeing is fairly pleased from an engineering standpoint that one of its aircraft exceeded design specifications, showing that their safety tolerances are fairly accurate and, as they like them to be, conservative. And any little bit of this kind of data only helps them engineer better aircraft in the future.

Of course, ~3000 dead people tend to dampen the pleasing benifits of such information, but if it leads to some guy with a slide rule somewhere figureing out new ways to keep the engine of the plane I'm sitting in from departing the wing in flight, I'd take it as a small victory from a terrible situation.

Why the WTC collapsed so fast

Good TV documentry last month on TLC or Discovery or whatever. Other than the WTC was symbolic for Osama, the towers were architecturally defective. One fire fighter put it "Never trust a building with a truss".
 
2002-02-24 12:22:54 AM  
FAA limits are 200 knots or less below 10,000', not that it made any difference here. And so what if the findings are published? You don't think the terrorists had already figured it out? Like maybe that's why they used planes and hit buildings? I seriously doubt terrorists are gonna learn anything new from the reports. "Hey Osama? I didn't know that plowing an airliner into a building at high speed with a full fuel load would make it burn and fall down! Did you?" "No I didn't Akmed! I'll make a note of it!"
 
2002-02-24 12:22:54 AM  
At this point, it doesn't really matter, does it?

Let it rest.

Pray for an asteroid or comet. At least it'll be faster than the way the world is going now.

"The second plane was flying so fast that it was in danger of breaking up. These guys exceeded even the emergency dive speed. It's off the chart."

Good engineers at Boeing I'd say. That's what they get paid the big bucks for.
 
2002-02-24 12:52:14 AM  
"The second plane was flying so fast that it was in danger of breaking up."

Sadly, it did break up... right after it hit the south tower...

"The second plane was flying so fast that it was in danger of breaking up. "

That sounds bogus to me: I seem to remember that the cruise speed of commercial gets is about 600 mhp, and the estimated speeds of both planes were lower than.

Someone who knows please tell us.

"That sounds bogus to me: I seem to remember that the cruise speed of commercial gets is about 600 mhp, and the estimated speeds of both planes were lower than. "

However when they travel at 600mph they are above 30,000 feet, at this altitude the atmosphere is much thinner so there is much less air resistence. However at the altitude the jets were traveling there would be much more air resistence, thus a danger of breaking up.

what does it matter...

its just so sad....

and we will pay the price for the rest of lives

Deef,

This should be rather common knowledge to even the dimmest person. You want to KNOCK SOMETHING DOWN, hit it faster. Remember these two from high school physics?

p = mv ...momentum = mass x velocity
F = ma ...force = mass x acceleration

And F=ma also explains that hitting it lower would cause it to collapse sooner. The mass of the building above the explosion x gravitational acceleration (9.8 m/s/s) equals the total force that the building above is exerting on the building below. Bigger means it'll come down faster.
 
2002-02-24 02:43:50 AM  
If you look at the 2nd plane hitting, you can see it turn and bank, and getting even more speed.
 
2002-02-24 02:51:34 AM  
how morbid...
 
2002-02-24 03:04:16 AM  
Let's see if I have this straight, momentum=mass x velocity, velocity=magnitude x vector. As near as I can tell, the impulse (i.e. change in momentum) was the main factor. Professor Frink must be sooo excited right now )

I agree with Bigpeeler...I don't think anyone will forget what or where they were at those moments....ever.

One fire fighter put it "Never trust a building with a truss".

As for that.... Is this FireFighter an engineer ? I design/engineer 'light plated' wooden trusses for a living. Yes, wooden, but they are stronger than you'd think. Those in the building were steel trusses, which are used in many bridges and other buildings.... they are VERY strong.

I guess he could have said "never trust a building with a truss, that has thousands of gallons of jet fuel burning in it.

Lunatic Fringe: Wise words on your part. But let us not forget "knowledge is power." And the knowledge of how to destroy a building is the beginning of acquiring the power to do so. Some things are better left unknown.

Wedge: And i'm so sure that the native people of Afghanistan are oh so well educated in physics. Thats why they are leaders in many fields of science and engineering. Oh, wait..
 
2002-02-24 01:07:04 PM  
Every time I see those pictures all I feel is depression and anger.
 
2002-02-24 01:27:11 PM  
Yes, "A day that will live in Infamy", a day that marks the beginning of WWIII, a day that precludes the end of this planet.
 
2002-02-24 03:43:50 PM  
When you go that fast, that low, with those types of planes shiat starts bending, breaking and falling off. Or so say my pilot friends. That second plane was just screaming when it went into the tower. The whole thing was just surreal to watch.
A pilot friend of mine said it was truly surreal to be in the air that day and have ATC tell you to land or get shot down. Many pilots upon hearing that an SCATANA was in effect and that an air defense emergency was declared thought it was a full blown nuclear attack because that was the only scenario that it was really intended for. Osama's boys definitely had their shiat together that day. Hit the WTC and attempt to decapitate US leadership. Imagine how bad it would have been if everything had gone off as planned.
 
2002-02-24 04:53:09 PM  
I think the point they're trying to make is that there's a difference between the speeds a plane is designed to withstand in the thin air of the upper atmousphere and the thick air below 10,000 feet.
 
2002-02-24 08:45:46 PM  
gee, the experts are suprised. I'm even more surprised.
 
2002-02-24 09:34:14 PM  
I'm glad they thought to include those pictures. I hadn't seen them before.
