please show some proof that FDNY KNEW either WTC1 or WTC2 would collapse before they actually did
those
older FF's you see manning the engines outside a structure fire are the trade's
best watchdogs, and are in
constant contact with their interior crew.
they know a structure
better than the people that
built them
there's no way they would have let 350 of their
own walk into (or stay within) a deteriorating structure
so the onus of any
proof here Dive, is on those who would otherwise claim them
all inept
