A short part of a letter written by a police officer at the time.

'At one point, about 10 minutes before the first collapse, a 30 foot or so section of the courtyard exploded straight up into the air. Just before the collapses, a series of deep, below ground explosions, then numerous explosions in the buildings upper floors. Then we ran. We felt the same deep explosions before the second collapse. This was not just the planes. THE BUILDINGS WERE RIGGED. There is no question about it. Hundreds of people know this''

How much more convincing is needed... John... 

Great so here is another:

More of the "aviation fuel" argument. First, the jets that crashed into the WTC were not fully-loaded with fuel. Even if the tanks were "topped off" before take offs, a good portion of the gas was consumed during ascent and acceleration. Second, the jets went into descent and were speeding along at over 500mph as practically sea level which sucks up great quantities of fuel. Third, when the planes hit the towers, the fuel, which was travelling at 500mph continued through the building, breaking the windows and exploding into giant fireballs!!!! Did all that fast-travelling fuel suddenly stop in less than 208 feet and remain as a giant fuel pool in the buildings ??? Logically "no" but since so many laws of physics were broken that day, anything is possible...
