The U.S. Navy MZ-3A Airship arrives at Lakefront Airport in New Orleans on its way to Gulfport, Ala. where it will undertake oil surveillance duty in the Gulf of Mexico, July 8, 2010. The airship was requested by the U.S. Coast Guard to support Deepwater Horizon Response operations of the Unified Area Command. The airship will be used to detect oil, direct skimming vessels, and look for wildlife that may be threatened by oil. The airship began the flight to the Gulf Coast last month in Yuma, Ariz. The airship is commercial A-1-70 series blimp, manufactured by the American Blimp Corporation. U.S. Coast Guard photo by Petty Officer 3rd Class Ayla Kelley.
