BBC The Sky at Night 'ET and the BBC'

[Non smoking gun]

The BBC's monthly Sky at night only runs for 20 minutes so it's something of a whistle stop tour.
Mr Sagan pops up quite a lot with his usual pithy comments. It was also interesting to see which sighting clips they featured.
BBC Four - The Sky at Night, ET and the BBC

Chris and Maggie dive into the archives to discover how the hunt for extra-terrestrial life in the universe has been reported by the BBC over six decades. Such luminaries as Patrick Moore, Arthur C. Clarke, Carl Sagan, James Burke and Alan Whicker discuss the eternal question of whether we are alone. The story of how the BBC has covered advancements in this scientific field is told from the birth of radio astronomy in the 1960s to the discovery of the first planets outside of our own solar system in the 1990s, and right up to probes exploring our neighbouring planets in the present day. There are also some rather more offbeat claims of UFO sightings, alien abductions and accounts of humanoid-like beings that supposedly live on Venus.
