London - Mina Tucker thought life had prepared her for most things. She had lived through two world wars and survived to see 13 great-grandchildren.
However nothing prepared her for the shock this week of a large lump of frozen urine falling from the sky and crashing through the roof of her house in Slough, near London.
Mrs Tucker (83) was enjoying a cup of tea in front of the television, when she heard the bang. She thought her house was being bombed. A fireman told her later it was probably frozen sewage which had dropped from a plane passing over Slough en route to London's Heathrow Airport.
