WWII bomb explodes at airport
A World War Two-era bomb exploded at an airport in the German town of Siegen Thursday, blowing a 50-foot-wide hole in the runway moments after a passenger plane had landed, police said.
No one was injured by the blast, which left a crater several yards deep and forced officials to shut the airport.
The bomb exploded at the small regional airport in the western state of North Rhine-Westphalia just hours before Queen Beatrix of the Netherlands was to land there Friday for a private visit in the nearby state of Hesse, authorities said.
The bomb, which was buried beneath the runway, blew up only minutes after a passenger plane had landed. Authorities said vibrations from the plane may have set off the aging bomb.
"We assume it was a large World War Two-era bomb," said a police spokesman in the town south of Cologne. "All other possibilities have been categorically ruled out."
Thousands of unexploded bombs are buried in Germany, many dropped by U.S. and British planes during World War Two.
Munitions experts are racing against time to find the bombs before they become unstable and explode. Police said they would investigate whether other unexploded bombs were buried at the airport.
