Bull! WTC 7 collapsed from the middle, pulling the rest of the building down. My concerns are about WTC 7.
Watch the full video, and then answer the question about what the explosions were? Several were caught on video and several Police, Firefighters and civilians reported them. WTC 7 had several security agencies housed there with all kinds of sensitive documents stored there.
All I'm saying is there seems to be more here than we have been told, that's all.
