They just defused a 500kg bomb in Cologne on January 21st.
This from the Smithsonian magazine:
"Although the country has been at peace for three generations, German bomb-disposal squads are among the busiest in the world. Eleven bomb technicians have been killed in Germany since 2000, including three who died in a single explosion while trying to defuse a 1,000-pound bomb on the site of a popular flea market in Göttingen in 2010."
"...But the government of Hamburg had recently brokered an agreement to allow the states of West Germany access to the 5.5 million aerial photographs in the declassified wartime archives of the Allied Central Interpretation Unit, held in Keele in England. Between 1940 and 1945, ACIU pilots flew thousands of reconnaissance missions before and after every raid by Allied bombers, taking millions of stereoscopic photographs that revealed both where the attacks could be directed and then how successful they had proved. Those images held clues to where bombs had landed but never detonated—a small, circular hole, for example, in an otherwise consistent line of ragged craters."
More than 70 years after being dropped in Europe, the ordnance is still inflicting harm and mayhem
