The base has sent 616 pallets of water on C-17 Globemaster III cargo aircraft to aid in the relief effort after a 7.0-magnitude earthquake struck the country on Jan. 12, 2010. Since relief operations began on Jan. 13, Air Mobility Command aircraft have delivered more than 323 tons of emergency cargo to Haiti.
