US-WEATHER-GUSTAV-MEDIVAC

As clouds roll into New Orleans on August 31, 2008, a US Air Force medical evacuation C-17 plane from the 314 Airwing from Little Rock, Arkansas,waits to take off from the Lakefront Airport in New Orleans in preparation of Hurricane Gustav. More than a million people fled Louisiana as killer Hurricane Gustav roared toward New Orleans, a fragile US coastal city still deeply scarred by the devastating 2005 Katrina storm. Highways out of New Orleans have been crammed since before dawn as people scurried to escape a monster storm that could slam the Louisiana coast as early as midday on September 1.
