Yes Over 20 witnessess including Paul Tully,owner of Tully construction and Mark Loizioux,owner of Controlled Demolition incorporated saw the pools of molten steel in the basement.And in fact you can see it yourself,in videos of the firemen digging in the pile.
Rosc, it was september that time of year, the temperature was probably in the 30's to 50's maybe even colder, and the ground temperature was even less, there could not have been pools of molten steel because for one thing it wouldve drained into the subway, and two, you conpiracy theorists have told us time and time againt that jetfuel cannot liquify steel. and the steel would have cooled by then, and also, trying to move a solid block of steel that huge would have been neigh impossible without there being serious evidence.
