Well in regards to building 7 I have to disagree. It experienced 2.6 seconds of free-fall according to the official investigation (source: http://ws680.nist.gov/publication/get_pdf.cfm?pub_id=861610 page: 44)

This means the building and its steel structure passed through minimum 15 floors with 0 resistance from below, violating the third law. How could this occur without the use of explosives?
