When the Structural Engineer who designed the WTC - Leslie E Robertson publically says that he believes that the WTC were brought down by a controlled demolition team planting charges in the buildings, I will consider the possibility.
Until then, anyone who espouses a conspiracy theory on the WTC collapse is a crack pot.
/36:48 - the CONSTRUCTION MANAGER of the WTC buildings recorded in January of 2001
""the bldg was designed to have a fully loaded 707 crash into it, the building could probably sustain multiple impacts from jetliners, because this structure is like the mosquito netting on your screen door, the jet plane is just a pencil puncturing the screen netting. It really does nothing to the screen nettting." describing how the buildings could take multiple hits from jet liners, the (tube) structure could take the hits.
37:22 - WORLD TRADE CENTER STRUCTURAL ENGINEER
describing how a 300 ton plane hitting a building designed to carry a 13,000 ton building wouldn't do anything.
Btw this recording was clearly from the 70's or early 80s judging by the glasses. lol
37:43 - (ANOTHER) WTC STRUCTURAL ENGINEER
"we designed the building to take the impact of the Boeing 707 hitting the building in any location"
37:50 - the CHIEF ELECTRICAL DESIGN ENGINEER of the WTC
"the plane already hit but what I noticed was, the lights were still in the lobby. That led me to believe that the plane never got to the core columns.... because the feeds for all the lights were in the core columns."
