MANPADS for the Syrian opposition:
a danger to commercial aviation?
"The vast majority of the attacks preceded 9-11. Consider what that means. At least into the early 1970s, if you wanted to take a couple of guns and a couple of pounds of weed on a US domestic flight, the smart thing to do was to put it in your carry-on. No chance you’d be searched. Even when things got tighter, it happened quite gradually. The distance between airport security before and after 9-11 is so vast that it makes no sense to base an assessment of current dangers on pre-9-11 experiences."
