Actually Tricky Dick Eastman proposed the "Zionist-engineered south-path-killer-jet-with-weaponized-air-vortices insanity, and its north-path-decoy-flyover" theory. So, in good twoofer fashion, "Citizen [sic] Investigation Team" ripped a page out of the anti-semitic Guns & Ammo subscribing survivalist's playbook. But they changed it up a bit. Either they thought the above "theory" was too stupid, or they wanted to pretend like they "discovered" some of the "evidence" for themselves. So they came up with the "stationary explosives" idea. Not as imaginative as Eastman's idea, but just as stupid.
