An engineer has captured a video of seemingly strange lights above Sheffield. In the footage the strange comet-like trails of light can be seen shooting around high above Sheffield United's football stadium - changing directions very quickly in the early morning sky. The video was captured by Peter Savage, 35, an electrical engineer at a security firm, on Friday December 15 at about 7am. Mr Savage was using the footage of the morning sky to calculate the distances between Mars, Venus, Earth and the moon when he noticed the unexplained phenomenon. Harry Ralston, 25, whose father owns Vision CCTV in Sheffield, South Yorkshire, where the footage a taken, said: 'We all sat there and said 'what the hell is this?' 'We had absolutely no idea what is was. 'We knew there had already been a meteor shower recently and these objects aren't moving in a straight line. 'They go straight and then turn around and shoot back the other way - there are two or three of them shooting about.' Mr Ralston
