SAVANNAH AIR NATIONAL GUARD BASE -- Cleanup efforts are underway for Hwy 21 near Savannah Hilton Head International Airport where a Puerto Rico Air National Guard WC-130H “Hercules” cargo aircraft crashed May 2.

Wreckage from the aircraft has been removed from the crash site and transported to a secure holding facility at Joint Base Charleston, S.C.

“The Air National Guard is committed to restoring State Route 21 and the surrounding areas affected by the crash of the WC-130 aircraft,” said U.S. Air Force Lt. Col.
