WWII bomb removed from Sendai Airport
SENDAI--An unexploded bomb found last month at Sendai Airport was disposed of by the Ground Self-Defense Force on Wednesday morning.
A bomb disposal squad of the GSDF's Sixth Division, based in Yamagata Prefecture, started the removal work at about 9 a.m. The procedure, including defusing the bomb, took about two hours to complete, after which the bomb was taken away by truck.
The airport's runways were temporarily closed for the disposal work, and at least 32 flights were canceled or delayed until the runways were returned to service at 11:26 a.m.
