A rare lenticular cloud is seen over the Pennines in West Yorkshire. Super-rare clouds normally seen over giant mountain ranges like the Himalayas have been spotted over Britain. Dad Jonathan Selwood-Hogg, 41, a business development manager from Huddersfield, West Yorks, spotted the bizarre lenticular formations and said they reminded him of the UFO from hit 80s kids movie Flight of the Navigator, while son William, five, saw a humpback whale. The strange shapes were thought to be caused by stable moist air travelling across the Pennines, creating a wave pattern in the cloud. More properly known as Altocumulus Lenticularis, the cloud type is said to be the biggest cause of UFO sightings around the world.
