World Trade Center Building 7 Rare Footage Truth Shown Like Never before

Rarely before seen footage of WTC building 7 being brought down in a "CONTROLLED DEMOLITION". Mind you, this was a supposedly SURPRISE ATTACK and yet they were able to prep WTC building 7 for a controlled demolition in mere hours instead of the nearly 4 to 6 months it would take to prep a building this size for a controlled demolition... Really???

How does Controlled Demolition work?

In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings.

Numerous small explosives, strategically placed within the structure, are used to catalyze the collapse. Nitroglycerin, dynamite, or other explosives are used to shatter reinforced concrete supports. Linear shaped charges are used to sever steel supports. These explosives are progressively detonated on supports throughout the structure. Then, explosives on the lower floors initiate the controlled collapse.[citation needed]

A simple structure like a chimney can be prepared for demolition in less than a day. Larger or more complex structures can take up to SIX MONTHS of preparation to remove internal walls and wrap columns with fabric and fencing before firing the explosives.
