Ha 911-nél az épületeket nem robbantással döntötték le, akkor hogyan lehetséges ez? (kép)

"illetve nem szabadesés közeli sebességgel omlott volna össze"

Itt a lényeg.Egyik torony sem a szabadesés sebességével omlott össze.Továbbra is kérdezem milyen iskolai végzettséged van?

Mintha a te linked nem propagandaoldal lenne :)

Mindegy, én azért jót nevettem.

"traktoros vagyok"

(most fordultam le a székről a röhögéstől).Azt hiszem nincs több kérdésem.Egy traktoros én nem vitatkozom, úgyhogy a magam részéről befejeztem ezt a vitát.

Bemásolom, ha esetleg nem találtad meg, itt a válasz a kérdésedre:

Claim: "We have been lied to," announces the Web site AttackOnAmerica.net. "The first lie was that the load of fuel from the aircraft was the cause of structural failure. No kerosene fire can burn hot enough to melt steel." The posting is entitled "Proof Of Controlled Demolition At The WTC."

FACT: Jet fuel burns at 800° to 1500°F, not hot enough to melt steel (2750°F). However, experts agree that for the towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength—and that required exposure to much less heat. "I have never seen melted steel in a building fire," says retired New York deputy fire chief Vincent Dunn, author of The Collapse Of Burning Buildings: A Guide To Fireground Safety. "But I've seen a lot of twisted, warped, bent and sagging steel. What happens is that the steel tries to expand at both ends, but when it can no longer expand, it sags and the surrounding concrete cracks."

"Steel loses about 50 percent of its strength at 1100°F," notes senior engineer Farid Alfawak-hiri of the American Institute of Steel Construction. "And at 1800° it is probably at less than 10 percent." NIST also believes that a great deal of the spray-on fireproofing insulation was likely knocked off the steel beams that were in the path of the crashing jets, leaving the metal more vulnerable to the heat.

But jet fuel wasn't the only thing burning, notes Forman Williams, a professor of engineering at the University of California, San Diego, and one of seven structural engineers and fire experts that PM consulted. He says that while the jet fuel was the catalyst for the WTC fires, the resulting inferno was intensified by the combustible material inside the buildings, including rugs, curtains, furniture and paper. NIST reports that pockets of fire hit 1832°F.

"The jet fuel was the ignition source," Williams tells PM. "It burned for maybe 10 minutes, and [the towers] were still standing in 10 minutes. It was the rest of the stuff burning afterward that was responsible for the heat transfer that eventually brought them down."

"Örülök, hogy tetszett az iróniám"

Világos, tehát akkor az eddigi válaszaid is mind iróniák voltak, vagyis amit mondasz azt te sem gondold komolyan.Én viszont komolyan kérdeztem hogy milyen iskolai végzettséged van.Mert látszik hogy semmiféle kémiai vagy fizikai tudásod sincsen, ennek ellenére te mégis hozzáértő emberekkel vitatkozol, ennek mindig az lesz az eredménye hogy folyton beégsz.Mint már mondtam én nem kívánom folytatni ezt a vitát, mivel érvelni sem tudsz rendesen ezért nem vagy vita partner.
