(1,443 posts)the source of the explosions at the WTC could plausibly come from electrical transformers or gas mains or whatever. but they could be from bombs going off. you can't know that without an investigation. that you are claiming these explosions are from exploding electrical transformers without any evidence tells me you are jumping to conclusion and have an agenda.
the explosions heard on the 9/11 video are too massive and violent to be coming from an electrical transformer. in the video you posted when the transformer blows up it sounds like a ordinary firecracker. but in the 9/11 video the explosion sounds like a massive 1000 lb military grade bomb going off. there's no comparison.
and if it was gas main exploding there would have been smell of gas everywhere and would have caused massive gas fires on the ground floors before the towers fell, but there was no reports of such.
