Sometime in early February , two nuclear submarines collided in the Atlantic. It was a fender bender and nothing serious happened. In the same month, two satellites collided in space, at very high speeds, and the result was the complete loss of both satellites as well as lots of space debris.

We tend to think of space and the oceans as relatively empty and of collisions as unlikely. Well, no matter how unlikely things are, they can happen. Are these Black Swans?

See The Black Swan Theory (Wikipedia).
