Actually, experts in implosion demolition don't think the WTC 1&2 collapses
look anything like an implosion demolition. See
for a link to a pdf file discussing
the subject. In any event, for such a grandiose scheme as implosion of the
WTC towers to be taken seriously, you first have to ask the question WHY?
WHY use implosion in addition to flying the airplanes into the towers? So
far, I never seen a logical rationale for doing so and there are strong
arguments for NOT doing so e.g. the risk of exposure with dozens of
demolition workers having unfettered access to the WTC towers for probably
weeks if not months prior to the attack. Have you any idea of how long it
would take to prepare for explosive demolition of the twin towers? How many
man-days of highly unusual activity to rig the columns with explosive
charges? All it would take is one person not in on the plot to bring it all
into the open.
