Operation Homecoming was a series of diplomatic negotiations that in January 1973 made possible the return of 591 American prisoners of war held by North Vietnam.

The first flight of 40 U.S. prisoners of war left Hanoi in a C-141A, later known as the "Hanoi Taxi" and now in a museum. From February 12 to April 4, there were 54 C-141 missions flying out of Hanoi, bringing the former POWs home.[3]

The War Powers Resolution of 1973 (50 U.S.C. 1541–1548) was a United States Congress joint resolution providing that the President can send U.S. armed forces into action abroad only by authorization of Congress or if the United States is already under attack or serious threat. The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30 day withdrawal period, without an authorization of the use of military force or a declaration of war. The resolution was passed by two-thirds of Congress, overriding a presidential veto.[7]
