For startes, it wasn't necessary to "melt" the steel in the WTC. The jet fuel fire was more than sufficient to heat the steel until it lost structural integrity, and soften the steel, and that is part of what led to the collapse. The collapses may well resemble other buildings that collapsed from controlled demolitions, but nobody anywhere has presented any kind of proof of these allegations what so ever.

Every time a major diaster happens there is always someone who pops up with some wild explanation of what happened. Remember the women who testified before Congress that they saw and heard the demolition charges go off that breached the levees in NO?? Same gig.

This group is just another collection of Fruit Bats looking for thier 15 minutes in the spotlight. The fact that they get any press coverage at all is proof of what a slow news cycle looks like...

So true. But it is so much easier to adopt a conspiracy theory than to find the steel tables, note that the stee at 800F has already lost almost half it's strength compared with ambient, and to find that jet fuel flames are more than twice that hot. Oh wait...it took almost 5 minutes to find that table. Yep, way too hard!

Had the asbestos insulation not been discontinued, they may well have been finishing the remodeling on the two towers about now...
