This is one of the few things that can be proven. Do you have examples of smilar thermal transformation to a frame structure. There have been lots of fires. If the government is so interested in proving it had no part in it why they don't build a frame similar to the one in WTC, not necessery that high of course, or find and an old one to scrap. We could see how thermal expansion works on the exact same box frame bridged with similar trusses and capped with hat trusses. I wouldn't like calculations or computer animation but real life research would be something. We know today the whole thing has become a matter of believe just like the UFO. Is the government so weak today to be unable to present something more substantial in its defence with respect to WTC than what it has done so far.edit on 31-7-2012 by Snakey because: (no reason given)
