A Gulfstream airplane that brought American doctor Kent Brantly who has the Ebola virus, departs Dobbins Air Reserve Base to pick up the other worker infected with the Ebola virus, in Marietta, Georgia August 2, 2014. The first of two American aid workers infected with the deadly Ebola virus while in Liberia landed in the United States on Saturday, en route to an Atlanta hospital for treatment. A chartered medical aircraft carrying Brantly touched down at Dobbins Air Reserve Base in Marietta, Georgia shortly before noon, a base spokesman said. Another member of the group, missionary Nancy Writebol, is due to be brought to the United States on a later flight, as the plane is only equipped to carry one patient at a time.
