And do you really believe every account of synchronized explosions right before the towers fell was imagined?
Imagined no, misguided yes. When the buildings began to fall the air pressure inside caused blasts of air to blow out weak points. Many observers mistook cause and effect.
It take a huge amount of expertise to cause buildings to drop straight down. And in this case, multiple buildings a fell perfectly.
That theory is fairly absurd when you consider what they would have had to do to insure they would fall straight down. They would have had to plan out exactly where the planes where going to hit the towers and calculate exactly what sort of damage that would do to the structure. Otherwise their detonations might cut the supports in an unbalanced way and end up causing the building to fall over rather then straight down.
It certainly appears that certain matters related to the 9/11 attack have been covered up or insufficiently investigated. But the wild conspiracy theories are simply that.
