ATLANTA — A small college in Ohio was thrown into mourning yesterday after a bus carrying the school’s baseball team tumbled over the side of a highway overpass and slammed onto the pavement 30 feet below, killing four students and the husband-and-wife drivers.The team from the close-knit, Mennonite-affiliated Bluffton University was making its annual spring training trip to Florida before daybreak when the charter bus crashed, scattering bags of baseball equipment across the road and splattering blood on the overpass. Some of the athletes climbed out the roof escape hatch, dazed and bloody.

“I just looked out and saw the road coming up at me. I remember the catcher tapping me on the head, telling me to get out because there was gas all over,” said A.J. Ramthun, an 18-year-old second-baseman from Springfield, Ohio, who was asleep in a window seat and suffered a broken collarbone and cuts on his face from broken glass. “I heard some guys crying, `I’m stuck! I’m stuck!”’

Investigators said the driver apparently mistook the exit ramp for a lane and went into the curve at full speed. It was dark at the time, but the weather was clear.

On the 1,150-student campus in Bluffton, about 50 miles south of Toledo, students and community residents — some wiping away tears — filled the gymnasium to grieve and learn more about what happened. When news of the crash appeared on television, students on campus desperately tried to reach some of the athletes on their cell phones.

Classes were cancelled, along with other sports trips that had been scheduled during next week’s spring break. Two airlines arranged for the players’ parents to fly to Atlanta free last evening.

Megan Barker, a sophomore from Bucyrus, Ohio, said she knew just about everyone on the team and described them as “a fun-loving group of guys.” She added: “They live as a family.”

Beyond the six killed, 29 players and their coach, James Grandey, 29, were taken to the hospital. He and six players were reported in serious or critical condition; many of the rest were soon released.

The bus had set out from Ohio the evening before and had travelled all night long before it went off the road and landed on its side about at about 5.30 a.m. on Interstate 75. Two vehicles travelling under the overpass were struck by the bus, but their drivers were not hurt.

“It looked to me like a big slab of concrete falling down,” said pickup-truck driver Danny Lloyd, 57, of Frostburg, Maryland. “I didn’t recognise it was a bus.”

The National Transportation Safety Board was called in to investigate.

Authorities said the husband-and-wife drivers had just boarded the bus, relieving another team less than an hour before. Investigators said there were no skid marks, and they hoped to tap into the bus’ computer system for clues.

“This is deeply impacting all of our students, faculty and staff. We know these people on a first-name basis,” said James Harder, the school’s president. “For now we’re pulling together and supporting each other as best we can.”

The baseball team had been scheduled to play its first spring-training game of the season in Sarasota, Florida today and had eight more games scheduled in Fort Myers, Florida.

It was not immediately known if the bus had seat belts. Motorcoaches like the one involved typically do not have seat belts in the passenger section.

The university is affiliated with the Mennonite Church USA. About one-fifth of the students are Mennonite, and the school stresses spirituality, but it is open to all religious backgrounds.

The church emphasises pacifism and non-violence. But unlike adherents of more conservative Mennonite denominations and the Amish, members wear modern clothing and use electricity. Smoking and drinking are banned on campus.

At a campus chapel service the night before the bus trip, students had prayed for safe travel for their sports teams and other students during spring break.

“Sometimes you take that stuff for granted,” said Katie Barrington, a junior from Brooklyn Heights, Ohio.
