A C-130 Hercules, like the one pictured in this file photo, evacuated four injured civilians from Port-au-Prince, Haiti, to Fort Lauderdale, Fla., Jan. 16. The mission was planned by the 618th Tanker Airlift Control Center's Aeromedical Evacuation Division at Scott Air Force Base, Ill. 618th TACC personnel have been working around-the-clock since Tuesday to support U.S. relief efforts in Haiti after a 7.0-magnitude earthquake struck the region.
