Clearly, the round (if it was in fact a bullet that caused it) didn't hit the magazine. You can still see the magazine safely in the weapon @ 00:46. In fact, I'd suspect that it was more likely a crappy round in the afghans own rifle that caused an over pressure upon firing, making the top cover of the AK's action blast off from the escaping gas.

Funny, when I was in boot camp in 1989, this issue:

M16 Manual

Was still in use. It really was a great training aid, considering the other FM's and TM's we were given weren't comics.

Dunno what Dainese is crowing about - the 'hit-air' system has been around for a few years now:

I flew out of Cleveland on Tuesday. Something about me peaked their interest and I was subjected to 'secondary screening' which involved a full turnout of my bags - the entire contents of my carry on, as well as my laptop bag. They inspected the actual volume of every liquid, paste, cream, gel, etc. The only thing i wasn't asked to do was turn on my notebook.

I especially enjoyed the 'trophy board' in cleveland's security line - A huge glass case on the wall with the caption "A *small* sample of items seized since Sept. 11, 2001". Inside the case was an artful arrangement of cap guns, claw hammers, knives, throwing stars, etc. Of course, I had none of those in my bags - The TSA goonette grudgingly allowed me to move on to my gate.
