Rather, testing a hypothesis through experiment is a fundamental principle of the scientific method, and is what NIST claims to have done with their model, yet they've proven unwilling to even show their video of their model comming down to demonstrate as much.
Scientific method:
Observations:
Fire was observed in WTC 7 after WTC 1 collapsed on it
Fire burns for 7 hours unfought, and uncontrolled
Explosions reported during the event
Step 2:
Take into account the construction of the building: Steel frame, long spans, unconventional framing system
Examine Thermitics: Were any brilliant sparkles obsrved? No such thing observed or reported
Examine explosions: Any 140 DB sequential sounds recorded in the entire duration of the event by camera in and around the vicinity. No such thing observed or reported
ANy damage consistent with bombs? None found
Determine whether or not fires can cause materials to explode? Yes
Most likely source: fires
Check the steel properties tables and determine the circumstances in which weakening or instability in the structure might initiate.
Observe the collapse: Initiation point? Interior
Progresses from the east side to the west side, before enough structure fails to render the building too unstable to continue standing.
Conclusion: Any characteristics of "controlled demolition" are purely cosmetic, and given a lack of any evidence to suggest otherwise, the hypothesis questioning about the possible use of explosive charges to cut the beams and columns is found to be insignificant according to the scientific method.
Evidence points to WTC 7 being a classic case of
progressive collapse, and initiated due to a scenario that was completely unforeseen at the time in which the building was being planned and engineered for construction.
