A B-52 Stratofortress claws for altitude moments after takeoff, its eight engines trailing the heavy black smoke characteristic of these Cold War-era bombers under full power. Flying from bases in Guam and Thailand, B-52s conducted thousands of 'Arc Light' bombing missions over Vietnam, Laos, and Cambodia, culminating in the intense Linebacker II raids of December 1972 that helped bring North Vietnam back to the negotiating table in Paris.
