You can call me a conspiracy theorist if you want to, but the notion that airplanes made those buildings come down is not logical in my mind. I've done a lot of work with heavy steel plate. I went to welding class for 2 years and studied structural steel welding. I practiced and practiced welding one inch thick steel plates together as a groove weld until it would pass a bend test. Even 3/4 inch thick steel plate is extremely strong. The only way to cut that is either with a liquid cooled band saw or a cutting torch. If I had a wall made out of 3/4 inch thick steel plate, a jetliner would smash up into a little ball and bounce off. There's a reason why bulldozers and tanks are made out of heavy steel plate.
Really...Think this through.. I can bend the frame on an old Ford I-beam truck but jumping a small ditch or having a head on collision. The I-Beam is made of steel - And steel bends, even without fire.
Now, take a Boeing 757. It weighs in at 127-140,000LBS (dependent on model)EMPTY. Now add the weight of cargo, luggage, people, 10,000 Gallons of fuel at roughly 7 Lbs per gallon. Take that and add it all up. Now push that total weight at 530MPH into a steel I-Beam of the type made for buildings and see if it doesn't buckle. Sorry, but even that is not strong enough to stay intact. The following is a summary of how the support structure of the WTC building was different than other buildings:
"The most significant advancement in the World Trade Center's design had to do with the towers' steel framework. Instead of spacing the vertical support beams evenly across the floors, the designers moved all of them to the exterior walls and the central core of the structure. These columns supported all of the buildings' weight,
but without lateral, or side-to-side, support from the floors, these columns would have buckled. The floors were built upon trusses, which bridged the distance between the exterior and core columns. Connected with two bolts on each end, these spans of rigid steel framework prevented the columns from bowing inward or outward. They also supported a 4-inch-thick (10 centimeters) floor made of reinforced concrete (reinforced concrete is embedded with steel for increased strength). Spray-on fireproofing, made from material similar to the rolled insulation in your home, further protected the integrity of the steel floor trusses, while the central columns were shielded by fire-resistant drywall. This economical design required less concrete and created nearly an acre of rentable office space on each of the buildings' 110 floors."
Once the planes compromised the outer walls and the floors, the buildings failed. AS for the supposed "explosions" and dust puffs seen coming from the floors as they collapsed, have you ever dropped a book onto a dusty rug or powdery dirt floor? Guess what, it puffs the same way, try it for yourself.
Again with the facts....
