Giant ice cube smashes roof An Angus couple are recovering from shock after a giant ice cube plummeted from the sky at hundreds of miles an hour and smashed into their roof. James and Flora Fleming were relaxing in the lounge of their home, The Gables at Barnhead, on the outskirts of Montrose yesterday when the ice meteor hit. They dashed outside to find five slates broken on the roof and the ice block lying shattered on their lawn. Experts reckon a 5kg block falling from a plane at around 1000 feet would plummet to earth at a speed of around 250mph.
