My brother was down there when that went on, said when people hit the ground it made a loud bang, they literally exploded like water balloons which is why you never see any photos of bodies. A friend of mine worked as an elevator repairman, was standing on the roof of a building right next to the WTC and said people fell right by him without making a sound. What was weird is 11 years later right on Sept. 11th he died falling down an elevator shaft. I always wondered if it was an accident or if he committed suicide.
