Scientists simulate jet colliding with World Trade Center

Back



Researchers at Purdue University have created a simulation that uses scientific principles to study in detail what likely happened when a commercial airliner crashed into the World Trade Center's North Tower on Sept. 11, 2001.

WarCrlme911,
so you are saying that intact floors 95-110 were not demolished? and these floors did not demolish intact floors 76-92? and no energy was expended doing this?

right.

did NIST or FEMA study events beyond initiation of demolition of intact structure below where plane struck?

no? I wonder why.

There are four interesting articles on NORAD at DNotice (org). They are "The NORAD Papers", "The NORAD Paper s II", "The NORAD Papers III" and The NORAD Papers IV. The last article (for the first time!) explains the mechanics of how NORAD radar operators monitored and identified aircraft flying over American airspace.

bIZAROsPRMN11 , Mr "Newton's third law suspended" (do you realize how much you give away with that one simple hair-brained comment? Do You?) since you 'profess' that you understand complet applied physics and finite element analysis::

A WTC panel weighing 250,000lbs and spanning 16 linear feet falls from the top od the WTC, the panel falls for 10 full seconds before impacting with the ground--expellling lots of dust.

QUESTION: How fast is the panel going when it hits the pavement?

Debate yourself first, then you will start to realize you are evidence free and have faulty research and junk science, like bigfoot, moon landing deniers, and flat-earth groups. Better off debating yourselves, you may win. It is like debating why 1 plus 1 is not equal to 2; you have lost when the first plane killed people in NYC. Your work looks like apologies for the terrorists.

"The relative smallness of energy absorption capability compared to the K.E. also sufficed to explain, without any further calculations, why the collapse duration could not have been much longer, say twice as long or more, than the duration of a free fall.."

Contact the editorial board, if you have something to complain.
But be informed, they are trained professionals in the field of engineering. You WILL actually need to back up your claims.

Watch bIZAROsPRMN11 --- who touts 'physics' in his posts RUN from an actual, real world physics question, one that msoe here can answer without putting pencil to paper. This kid is realy bland.

You are up bIZAROsPRMN11:

YOU CAN'T ANSWER

It is already well established, with your 'concrete blocks to simulate WTC construction' hairbrained experiment, and your inabilty to answer a simple 8th grade physics question, along with your misunderstanding of Newtons Laws that you posess zero abilty in applied physics.

Your research skills are equally as appalling, and, in many ways, humorous to those of us with an actual functioning brain.
You, my dim witted friend, are versed in Tom N' Jerry physics--real physics? Nope

LiteWaiter,

"Taken together these things prove that high levels of our government dont want us to know what happened and whos responsible."
Lt. Col. Robert Bowman, PhD, U.S. Air Force (ret)

well, LiteWaiter, that is how many folks in our government get their jollies.

"It also gives us a very special, secret pleasure to see how unaware the people around us are of what is really happening to them."

hypnotstcollector,
"absurd video"? it is probably helpful for 95% of U.S. adults whose understanding of physics is limited to watching roadrunner cartoons. it, of course, proves nothing about the demolition of WTC 1.
"Folding Back Wings"? not according to Perdue professor Mete Sozen
"...one wing hit the ground; the other was sheared off..."
Mete Sozen, professor of structural engineering at Purdue - Popular Mechanics, March 2005

did Hitler use conversational hypnosis?

GetSum951,

"if you'll just listen"

okay, I'm listening.

"I think" ... "maybe it was"..."I think"..."trust me!"

"trust me"? , ah, I get it. faith based government. Britney understands to.

"Honestly, I think we should just trust our president in every decision he makes and should just support that, you know, and be faithful in what happens."
Britney Spears - September 3, 2003

Martian conspiracy? your joking of course. we ALL know Osama suspended Newton's third law on 9-11-01.
