SAN FRANCISCO (AP) — Delta Airlines says a Cincinnati, Ohio-bound flight at San Francisco International Airport had to be deplaned after a baggage tug hit the aircraft.

The flight was scheduled to leave at 11:15 a.m. Tuesday. Delta spokesman Morgan Durrant said the plane was at the gate when the tug accidentally hit the nose gear.

There was no evidence of damage, but Durrant said Delta put the 138 passengers on another aircraft out of an abundance of caution.

The next flight left at 1:59 a.m. and arrived in Cincinnati at 6 a.m.

Durrant said no one was hurt.
