Although the saying, 'Pigs might fly' may bring a smile to one's lips, even stranger things have been reported as appearing in Britain's skies over the centuries. Eye-witnesses have testified that various terrifying and bizarre forms have appeared in the skies, from ghostly planes, phantom airships and UFOs, to reports of sky serpents, celestial dragons, flying jellyfish, rains of fish (or blood, or metal, or frogs) even reports of a griffin seen over London! It also considers reports of haunted aircraft hangars and airfields. Shadows in the Sky compiles hundreds of accounts from the spine-chilling to the downright bizarre, that'll keep your eyes fixed looking upwards!
