Lynn Margulis, Ph.D., ScientistAwarded the National Medal of Science, 1999
You can't do science when you are deprived of the evidence, and when your hypothesis is the least valid instead of the most likely. When the most likely hypothesis in the case of Building 7 wasn't even mentioned -- this is not science. It's trying to prove preconceived ideas.
The WTC buildings came down because they were very carefully controlled demolitions with high-explosives that had to be planted many weeks, if not months, in advance.
