Ridley Scott inspires Network Rail’s cave-exploring drone
By Chris Baraniuk

When Hollywood director Ridley Scott filmed astronauts looking for aliens in his 2012 movie Prometheus, little did he know that it would one day inspire a Network Rail drone project.

But, bizarrely, that's exactly what has happened. Network Rail, which owns and maintains most of the railway infrastructure in Britain - from vast stretches of track to thousands of bridges, tunnels and level crossings - has long sought cheaper and easier ways of surveying the many underground caves and abandoned mines dotted around its property.
