The space shuttle Endeavor just returned from a delivery mission to the International Space Station where it brought, among other things, new bedrooms and a system for converting urine and sweat into drinkable water. But when it reentered the atmosphere, it caught much of California's attention. Why? It created a double sonic boom, that's why.

As the video above shows, the booms were incredibly loud, audible throughout Los Angeles and the surrounding areas. People unaware of what was happening thought an explosion had gone off in their neighborhood, causing emergency lines to be flooded with calls. Luckily for all involved, Endeavor landed safely and no one was hurt. Hit the jump for another video of the shuttle's reentry.
