10. Philip Spencer, a policeman in London, moved to Ilkley Moor after leaving his job. While getting some photographs of the moor, he heard a humming sound and saw a small green creature, around four feet tall.
That creature moved away quickly and when Spencer shouted, it turned and waved an arm dismissively, which is when Spencer said he took this photograph. It moved faster than a human.
He followed it and saw a huge silver saucer disappear into the clouds. He realized the humming sound was from the saucer.
