I watched three BBC4 documentaries in a row last night which is unheard of as our pub quiz was cancelled at the last minute. The middle one was the entire story of the landline in the UK. Well worth a watch, as it's an incredible story. The first one was the best though - the decommissioning of a North Sea oil rig and it's removal, demolition and recycling. The last one was about meteorites, which focused on that Russian one which hit the earth in 2013 and was captured on loads of dashcams giving the scientists invaluable clues. Any other documentary recommendations on BBC4 or any channels?
