The SA-75 is not a MANPAD. Do you know what that acronym means? The SA-75 (AKA SA-2) is a high altitude anti aircraft guided missile fired from very sophisticated fixed launching sites. They were deployed to Cuba and used by in NVA in North Vietnam. ISIS does not have this weapon.
I do know a man with a secret decoder ring who can tell us exactly what happened and he doesn't even need to make wild speculation based on things he read from incomplete and inaccurate news accounts.
Yeah, that ain't no MANPAD! YIKES!
Secret Decoder Ring says we should blame the center fuel tanks and not Jihadists.
