Fair enough--that makes sense! PartyTime, you really should have gotten away from the University of Margaritaville for a while. Engineers, architects and all construction hands learn early that there are two main types of steel in buildings. Columns and beams. Beams are horizontal members. Columns are vertical load bearing supports for beams. If you walk onto any construction site in America and start to talk to the crews about "vertical beams", they will first look at you with total astonishment at your naivete, then they will probably escort you off the premises ASAP as a dangerous risk to their safety. Please take the time to watch as many of these demolitions as possible. Then point out any single one where leaping columns defy gravity: implosionworld.com I dare you. Find one instance where a structure coming down due to gravity (after charges break up the structure) result in flying columns, or beams for that matter. I don't think you can do it. :) Now just for comparison's sake, let's review the flying steel at the WTC collapse: reopen911.org I bet that if you go back and forth here, you'll soon agree with me that what happened at the WTC looks absolutely nothing like what happened to any of the structures that gravity brought down on the Implosion World website. *** Finally, let's compare a couple of photos of explosions involving modern military ordnance, something in the RDX or Semtex family: Image #1: billcarlisle.tripod.com Image #2: serendipity.li [The Univ. of Sydney images about about 2/3 of the way down the page.] Notice the similarities in the debris clouds? Curious, isnt' it.
