ROMULUS, Mich. -- A Delta jet headed to Atlanta with 180 passengers aboard has slid off a taxiway at Detroit Metropolitan Airport. No one was hurt.

Delta Air Lines spokesman Morgan Durrant  says the plane "may have hit some black ice" before sliding from the taxiway onto a grassy area around 6:40 a.m. Monday.

Durrant says the passengers safely got off the plane and were rebooked on a flight scheduled to take off later in the day.

Airport spokesman Brian Lassaline  says the plane was towed to a Delta hangar and didn't appear damaged.

He says conditions were wet, and the surface temperature dropped overnight. The cause of the incident remains under investigation.

Lassaline says there were no other disruptions to flights at the Romulus airfield Monday.
