Чудовий опис наслідків астероїду, що вбив динозаврів, на BBC:

The plume spread east and west until it enveloped the entire Earth. Then, still gravitationally bound to the planet, it rained back down into the atmosphere.
As it cooled, it condensed into trillions of quarter-millimetre droplets of glass. These shot down towards the Earth’s surface at about the same entry speed as the space shuttle, heating the upper atmosphere so much that, in some places, land plants caught fire.
