It might be simpler than that. Terrorists could simply hijack one of the thousands of tanker trucks filled with gasoline or toxic chemicals that are on every major highway in this country and drive it into a target of innocent civilians. Imagine the carnage of an exploding tanker truck plowing into a hospital, school or shopping mall. Such a heinous attack might backfire as Americans are already sick of the current small attacks by Muslim fanatics and the influx of thousands of “refugees” from Muslim countries instituted by Obama. Such even more vicious attacks could bring a swift backlash with mass deportations, inturnment camps and the closing of mosques

Unless rigged with explosives they’d just burn and not explode.
