The shock waves caused by the meteor ripping through the atmosphere over Russia last weekend were picked up by detectors halfway around the world. The detectors were originally deployed to pick up nuclear blasts in the atmosphere.
Mankind was very lucky this past century. Two major meteor events have occurred over Russia-- Tunguska in 1908, and Chelyabrinsk days ago. Had either happened at a critical point in the Cold War, or had a similar body exploded over a major city, it could have sparked a nuclear exchange.
