TOKYO: Japan will sweep regional airports for more unexploded ordnance after a bomb dropped by the United States in World War II blew up on a taxiway in the south, the country's transport minister said on Friday (Oct 4).

A 500-pound bomb, believed to have been dropped during World War II, exploded at the Miyazaki Airport in Japan on Wednesday.

A U.S.-made bomb dating back to World War II exploded at the Miyazaki Airport in Japan on Tuesday, damaging a taxiway, and causing a disruption in air traffic at the location.

A bomb dating back to the Second World War has exploded at an airport in Japan, narrowly missing a departing Japan Airlines flight.

The explosion of a World War II-era bomb at a Japanese airport this week has prompted the government to do a wider search for other possible unexploded bombs at airports that were targeted during the conflict.

Experts say while such bombs are usually safe and damage likely to be limited, the difficulty is in finding those that are buried deeper.

Safety is an integral part of travel; when it is threatened, there can be disastrous consequences. While travelers can anticipate occasional threats, some things can not be controlled or predicted. A situation like this unfolded in Japan recently due to a bomb threat.
