Architects & Engineers for 9/11 Truth

Architects & Engineers for 9/11 Truth is an American non-profit organization promoting a controlled demolition conspiracy theory, disputing accepted conclusions around the September 11 attacks, including the 9/11 Commission Report, as well as FEMA's "WTC Building Performance Study" (2002).

 * How did the structures collapse in near-symmetrical fashion when the damage was clearly not symmetrical?
 * Nathan Lomba, S.E., P.E


 * The main puzzle was how two buildings with highly asymmetric damage could fail vertically downwards into the strongest part of the buildings — their steel-columned cores. And not only fail vertically, but at a speed that indicated structural resistance being removed sequentially from under the collapse wave. Few engineers would imagine buildings a quarter-of-a-mile high failing vertically, into their main structures, rather than failing laterally — given the eccentric damage.
 * John Watt, C.S.E.


 * Symmetrical collapse requires simultaneous failure of all supporting columns.
 * Charles Pegelow, P.E.


 * Perhaps it might be possible that the building floors would pancake down, but the huge steel columns would be left protruding out the top as the floors went down.
 * Lynn Affleck, P.E.
