Bomb disposal
On 2 June 2008, work on the channel brought up a "Hermann" Second World War time bomb. Residents were evacuated, tube and rail services were disrupted, and flights from London City Airport were curtailed during the emergency. The 67-year-old, booby-trapped bomb was finally made safe, after five days, in a controlled explosion that threw 400 tonnes of sand into the air. Major Matt Davies, of the Army Bomb disposal unit said "If it had gone off in wartime there would have been large fragments up to a mile away which could have destroyed buildings and sewers". He added "This is the biggest unexploded bomb we have found in central London."
