the problem with trying to parse what happened with the buildings brought down by aeroplanes and the WTC7 is all the material has been shipped away, so that horse has bolted anyway
What do you think is the most plausible explanation to the collapse of building 7?
Well despite what some folk say(loose change) there was some serious fires raging in WTC7 and structural damage. The problem i have saying my own theory is, then i leave it open to challenege and it will require me to go get videos with time stamps, and a lot of the supporting evidence will take time to gather. I used to debate this often years ago and i'm not sure if i want to start.
But anyway i'll state what i think happened.
I think Flight 93 was meant to hit WTC7 , if you go back and listen to some reports they actually announce another explosion is heard (this is the problem i would have to go and source all these videos again, get time stamps to show when things were said) at around the time the flight if it hadn't crashed would be coming into New York. It can sorta "explain" why 3 buildings fell with 2 aeroplanes.
So i'd imagine that Building 7 came down the same way as the two towers came down, minus the aeroplane. Probably through some structural weakening from pre-planted explosives.
