It's not altogether uncommon to hear about double rainbows, but what about a double meteor strike? It's a rare event

I don't know about that.

That was my first thought. Of course, Shoemaker-Levy was a comet and those tend to break up when they enter the inner solar system.

The meteor in the article very likely broke up when it hit Earth’s atmosphere. Most of the pieces would then burn up in the atmosphere. The pieces that hit were the ones that were big enough to make it to the ground.
