Communication is the key
OSAN AIR BASE, Republic of Korea -- Tech. Sgt. Richard Davis, 607th Support Group satellite wide band and telemetry systems technician, practices a unique capability that allows Osan computers and telephone traffic to be routed up to a satellite and then on to its destination, instead of "flowing" through cables in the ground. Establishing back-up systems to link normal communications networks is critical should normal communications systems fail during a contingency. (U.S. Air Force photo/Staff Sgt. Lakisha Croley)
