Residents of Yorkshire County in England were left baffled after mysterious parallel lines appeared in the sky on 27 September. Photos posted online show three rows of white lines, which users said looked like they had been drawn by someone.
Shortly after images of the sighting were posted online, residents of other English counties and cities reported that they too had seen the bizarre lines.
