No way it just came down freefall from jet fuel. I don't care how much engineering you took in school. Anyone who's ever worked with, cut and welded steel first hand, can tell you there is no way. Thermite is certainly plausible...but it was controlled demo either way. Buildings NEVER drop straight down freefall speed without lots of help.
My husband who is a welder and I just said that. It might melt but at some place on the beam it would still be solid causing it to fall or lean sideways.

i am an aircraft engineer...Jet fuel do not burn hot enough to melt steel..even if it did would not take a building down like that without help....
