Diane Bowers took the photograph while on holiday at the Sierra Nevada mountain range in Spain. Mother-of-two Mrs Bowers, 45, said: 'I couldn't believe my eyes when I spotted this cloud. The sky was so clear, just a pure blue, apart from this one cloud that looked just like a flying saucer. It was one of those moments that I will never forget.'The photo now takes pride of place in Mrs Bowers's living room at her home in Peterhead, Aberdeenshire.
