Raspuns la intrebarea lui Mircea
Posted by Pendulul lui Foucault under De ce, Plictis^2, intrebari intrebatoare | Tag-uri: 9/11, afganistan, fagaras, ion gavrila ogoranu, Mircea Badea, osama ben laden, otel, rezistenta anticomunista, teoria conspiratiei, WTC | Aseara am vazut In gura presei cu Mircea Badea din 11.02.2008 . Mircea vazuse un film si se gandea ca americanii nu il cauta pe Osama ci doar se fac… Azi am citit Comentariu la Carti Interzise . Articol despre Carti Intezise, omu vine cu pasarelele lui…
M-am uitat si eu la Afganistan pe Wikipedia si am vazut ca are o suprafata de 647500 km² aproape de trei ori cat Romania (238392 km² conform Wikipedia), suprafata din care mai mult de jumatate e munte. mai mult decat suprafata Romaniei 
Tinand cont ca grupul Ogoranu a rezistat fara sa fie prins intre 1948 si 1956 doar in masivul Fagaras iar Ion Gavrila Ogoranu nu a fost prins pana in 1976 in Romania Comunista este oare imposibil sa nu fi prins timp de 7 ani in zona muntoasa a Afghanistanului?
Tot in emisunea respectiva Mircea face o referire la 9/11 si la faptul ca otelul nu se topeste la temperatura la care arde kerosenul. Adevarat dar otelul la 600°C otelul isi pierde cam 50% din elasticitate. Conform Popular Mechanics
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.”
