NEW ORLEANS (AP) - A U.S. Coast Guard plane and a Mexican Navy vessel are searching the Gulf of Mexico for a small plane which flew hundreds of miles (kilometers) beyond its destination in Louisiana.

The Coast Guard says Steven Schumacher of Missouri was flying alone and probably crashed hours after missing his scheduled landing at 8:30 p.m. Wednesday in Gonzales, near Baton Rouge.

A Coast Guard news release says Schumacher's family reported him overdue two hours later. A Coast Guard spokeswoman, Petty Officer Sydney Phoenix, says an online flight tracker showed the plane's last known position about 11:40 p.m. Wednesday, about 440 miles (700 kilometers) past Louisiana's coast.

Phoenix says Schumacher flew out of Cape Girardeau, Missouri.
