Aircraft wings are a bit the same, Brian, they have to flex.

Heard it said on one of those "Greatest Engineering Disasters" docs on Discovery Channel or some such, that if you're sitting on a bridge in traffic, the only time you need to worry is when it STOPS shaking. Same up here, and we're not even set up for earthquakes in any way. Bridges shake. They need to have room to expand and contract with temperature ranges of ~60 degrees C, extreme wind and weather, heavy loads, or in the case of Japan, earthquakes. A little unnerving, but totally necessary. The "swaying skyscrapers" of big Japanese cities are a marvel of engineering. I sure wouldn't want to be up there when they do that, but the alternative is way worse.
