Investigators have returned to the scene of a small plane crash that has killed one person.

Federal Aviation Administration spokesman Lynn Lunsford says the pilot of a single-engine Beechcraft Bonanza was killed when the plane crashed last night near Yukon, about two miles south of Wiley Post Airport.

Lunsford says the plane was registered out of Fort Worth and was flying from Lawton to Oklahoma City. He says witnesses reported that the plane dove straight into the ground. Authorities have not released the pilot's identity.
