Why do most of Americans still think planes brought down the Twin Towers? Because to them, the official story of why the Towers collapsed was believable. Large aircraft loaded with lots of fuel crashed into the Towers at high speeds and penetrated inside before exploding thereby causing extensive internal damage. Then the resulting fire weakened the steel causing the top sections to collapse down thereby pulverizing the rest of the buildings.
The twin towers were rigged with explosives! Remember the dancing Israelis?
