CARTERSVILLE, Ga. (AP) — Two weeks ago, Dent M. Thompson, vice president of Phoenix Air, received an interesting phone call while he was on vacation in the mountains of North Carolina. One of the leading air ambulance companies in the world, Phoenix Air had developed what it calls an Aeromedical Biological Containment System (ABCS), and the U.S. State Department wanted to know whether the unit would fly. "I got a call from a senior doctor with the U.S. Department of State, who asked me if the ABSC was capable of handling Ebola," Thompson recalled.
