Huge WWII bomb defused
A World War II-era bomb that was discovered during construction for the 2012 Summer Olympics, was safely destroyed by British Military. The German bomb weighs 900 Kg and was the largest one found in three decades according to London Metropolitan police. If the bomb had exploded, it would have created a large crater and sent fragments flying close to a kilometre. Nazi planes dropped thousands of bombs on London during the war and unexploded devices are found from time to time.
