Their names weren't released by authorities. Both freed themselves from the wreckage, walked out of the woods and across the airfield to report the crash to airport personnel, said Capt. Jay Wiggins, director of Glynn County's Emergency Management Agency.
The Grumman American AA-5 airplane crashed about 12:35 p.m. in dense woods north of the airport's main runway.
It went down behind the Stambaugh Aviation hangar, which is at the edge of the airport property, said Jett Lamkin, spokesman for the Glynn County Airport Commission. The plane was en route to St. Augustine from North Carolina, he said.
A preliminary investigation indicated the plane was blown off the runway by a strong crosswind, Mr. Lamkin said.
Wind gusts of 14 to 23 mph were reported at the time of the crash, he said.
The Federal Aviation Administration and National Transportation Safety Board were notified, Mr. Lamkin said.
Commercial air traffic at the airport wasn't disrupted, officials said.
