A US Air Force photographer captured a perfect smoke ring during a missile launch today, an awesome phenomenon I've never seen during a rocket launch before. The unarmed Minuteman III intercontinental ballistic missile was launched at 3:36 a.m. PDT, at Vandenberg Air Force Base in California. The missile was randomly selected to test and evaluate the system's operational state. And if the smoke ring is not extraordinary enough for you, try this: a fire angel was also captured. via Gizmodo.
