Yep Chadgores description in number 9 above is printable version. Hexogen in the form of Cyclonite has been around since prior to second world war. Basically C3H6N6O6 for all those playing the home game of anarchist are us.
It's right up there equal to C-4 in relative equivalency factors and brisance. Multiple sources possible as to where it came from.
I think the tampon bomb is the big threat on commercial aircraft these days........
I wonder how many pounds a female jihadist can put "up there?" Enough, I guess. You need a non metallic cap though, right? I'm guessing the bombs were pre-primed with identical timers. No smoking fuse this time. Or perhaps they lit them in the lav? Preset timers takes away the "second thoughts" factor, and the Richard Reid "screwup factor."
Looks like pre-fight security check in is going to get more interesting. When the TSA starts advertising for OBGYN's we will know for sure.
Was that "unclaimed female body" ever claimed? In a story a day or two ago, all the bodies from the first plane were claimed except for one female body.
