ST. MARTIN ISLAND, Mich. -- U.S. authorities say they've rescued a Canadian man whose small plane crashed into Lake Michigan over the weekend.

U.S. Customs and Border Protection says a helicopter crew from its Office of Air and Marine was returning Saturday evening from training in northern Michigan when a mayday call was heard from a pilot. The crew responded to St. Martin Island.

Customs and Border Protection says Canadian pilot Robert Kelly was spotted getting out of the plane and his wife was circling the crash site in another plane.

The crew landed on a rocky beach. Kelly had only minor injuries.

The Customs and Border Protection helicopter crew involved is assigned to the Great Lakes Air and Marine Branch at Selfridge Air National Guard Base in suburban Detroit.
