An American doctor in serious condition after he contracted Ebola was on a specially outfitted plane on the way to the U.S. for treatment Saturday morning, the organization Samaritan's Purse told NBC News. Dr. Kent Brantly — the first person infected with Ebola to be transported to the U.S. — will land at Dobbins Air Force Base in Marietta, Georgia, before he is transported to Emory Hospital in Atlanta.
