There were a couple of very interesting TV programmes about meteorites and their effects on Earth. The programmes were on simultaneously.
BBC2 covered historic hits, including the one which caused the extinction of dinosaurs and other life on earth. Sites of craters were visited - the one on the Yucatan Peninsular in Mexico was fascinating. NASA experiments were discussed, as was the latest meteor over Russia.
Channel 4 concentrated on the Russian meteor and the search for debris.
