The Air Force, Coast Guard, and Army continued their frantic search on Wednesday, Nov. 6, for an airman who fell out of a C-130 aircraft over the Gulf of Mexico, according to authorities.

Rescuers scoured a 700-square-mile area off the coast between Fort Walton Beach and Pensacola, Florida, following the 11:30 a.m. CT mishap on Tuesday, Nov. 5, when the airman from the 24th Special Operations Wing fell from the plane, officials said.

“The search area continues to expand and adjust as efforts continue,” authorities said in a statement.

The Coast Guard said the serviceman, identified only as a staff sergeant, dropped about 1,500 feet into the water and his parachute deployed, WEAR-TV reported.

If anyone on the water sees or suspects anything, please stay vigilant and contact U.S. Coast Guard Sector Mobile at (251)-441-6211.
