Not so rare after all... Asteroid impacts, that is. If these articles are accurate, the Earth is being smacked upside the head by a couple of asteroids every year. That's not quite as scary as it sounds, though. Remember, roughly 3/4 of the earth is covered by ocean, and about 1/40 of that 1/4 that is land is covered by cities – so each asteroid has only about one chance in 160 of actually hitting a city. That means we should expect an asteroid to smack down a city about once every 80 years. If an asteroid landing outside a city hurt or killed anyone, well, they were just having a very unlucky day.
There are days when the idea of an asteroid taking out Washington, D.C. is an attractive one.
Most days, actually.
Maybe every day.
