The idea that a building’s walls will stand up seems as safe a bet as gravity's pull or the sun's rising. Most of us don’t worry much about whether our apartments, offices, supermarkets, or schools are going to collapse on us as we go about our daily routines. But should we? National Geographic takes a look at buildings around the world that despite having appeared structurally sound, some for years on end, came crashing down in a moment's notice. Dig deep into the histories of these buildings to discover why.

National Geographic DVD Exclusives
For the first time ever, National Geographic presents its programming in DVD-R format. Available exclusively through this site, you can now own more of our award-winning specials and documentaries in a high-quality DVD format.
How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD Exclusives Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD Exclusives titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
