So then, some kind of explosive was used in addition to the planes and fuel.
Who planted that explosive? It had to be thousands of pounds of high explosive. Stuff that's not easy to find by civilians so it had to be some military or government agency. That volume of explosive had to be snuck in without anyone noticing.
When and how could that happen?
Plus whoever did it had to be in cahoots with the Saudis who flew the plane because of the simultaneous crash/bomb detonation so I think that eliminates the CIA or NSA as the culprits, it had to be non-US operatives, right?
How did foreign agents manage to sneak tons of H.E. into both buildings, plant it, and hide it for days/weeks/months without detection? And it had to be TONS because you're saying that a plane full of fuel was obviously insufficient.
Why did they then not take credit for the bomb portion of the act?
How has this secret been kept so tightly for so long?
So many questions...
