Today's cool picture

This is a photo of a live fire drill during an annual training exercise in Paju, South Korea. The gun is a 155 mm howitzer. What qualifies this photo as a "cool picture" is that little football-shaped blob near the top center of the picture. It's not a football. It's not a bird. And it's not Photoshopped - that's the real thing.

You have just seen a photograph of a bullet — a really big bullet  —  in flight. Mr. Lim, we applaud in your general direction.
