World became a key military contractor during the Vietnam War, flying troops and equipment between the war zone and World's base at Oakland International Airport. On March 29, 1975, World operated the last airlift flight out of Đà Nẵng, Vietnam. Two 727s were flown to Đà Nẵng, one of which had Ed Daly aboard. Thousands rushed the airplane and it took off on a taxiway under heavy fire. The aircraft with Daly aboard started its takeoff roll with the 727's back airstairs still down with Daly fending off additional people trying to leave due to over capacity (The film of this was later broadcast on the "CBS Evening News" on March 30, 1975). When the airplane landed at Saigon, there were 268 people in the cabin and possibly 60 or more in the cargo holds. World did not return to Đà Nẵng until April 17, 2002, then with an MD-11 aircraft to pick up a team of people resolving Missing-In-Action cases from the Vietnam War.
