Me knows you're correct
I got what I call the heebie jeebie eeries when I passed an Amoco facility right outside O'Hare, it has a dozen enormous tanks and I've complained for a long time, seemingly not protected. I always envision a SAM hitting one and thousands, I mean many thousands would die. It is located right by the trailer court where the O'Hare plane crash of May 25, 1979 at Chicago's O'Hare International Airport and resulted in 273 deaths.
SAM is Surface to Air Missile. It's used for taking out aircraft from the ground. The "low tech" approach for those storage tanks is to open the valve on a tank of gasoline and light it off. A jihadi with a death wish and a book of matches could it with ease.
