OCEAN CITY, Md. — Federal and state authorities searched swaths of coastal Maryland on Thursday for a small overdue plane with two people aboard.

Some debris that appeared to be from a plane and an oil slick was spotted early Thursday in the search area off Assateague State Park, located on a barrier island bordered by the Atlantic Ocean.

Coast Guard spokesman Petty Officer Ronald Hodges told The Daily Times of Salisbury the four-seater Cessna 172S was carrying two people when it took off from Martin State Airport on Wednesday evening.

The Guard has since identified the missing pair as Banica Richard Robinson and Marcson Ngwa.

Hodges told the newspaper that the plane was last seen practicing touch-and-go landings near the Ocean City Municipal Airport, about 45 minutes after takeoff.

He identified the plane’s tail number as 615JA, which corresponds to a plane registered to a Baltimore flight school, Middle River Aviation.

Maryland Natural Resources police spokeswoman Candy Thompson said a dive team was dispatched to the site where the oil slick was spotted off Assateague State Park.

State Police are heading up the multiagency search that began Thursday morning.
