That's a very good point, but I'm pretty sure that in response to Pan Am flight 103 a lot of work was put into making cargo holds and containers able to withstand a decent sized blast.

Like you, I can't find the exact info, but I'm pretty sure it was an episode of Aircrash Investigations. I saw a repeat with that episode a few months ago.

I didn't come away with the impression that they'd actually implemented blast-proof though, just that they'd redesigned so that some blasts wouldn't dramatically cause airframe failure.

Well, but that's still pretty cool. I didn't know this at all.
