COLUMBUS, Ohio --A charter bus with 16 students from Queens on board overturned Sunday in Columbus, Ohio. Nine children and two adults were transported to a local hospital, but their injuries are minor and all are expected to be treated and released. The bus overturned at about 7:30 a.m. and rolled down a ramp of I-70 eastbound. The bus, which was also carrying three adult supervisors, was en route to New York from St. Louis. There is still no word on whether slick roadways or speed played a role in the accident. The students were returning from a robotics competition in Missouri.
