The weapon was presented by Nazi propaganda as a retaliation for the bombers that attacked ever more German cities from 1942 until Germany surrendered.
Beginning in September 1944, over 3,000 V-2s were launched as military rockets by the German Wehrmacht against Allied targets during the war, mostly London and later Antwerp and Liège. According to a BBC documentary in 2011, the attacks resulted in the deaths of an estimated 9,000 civilians and military personnel, while 12,000 forced labourers and concentration camp prisoners were killed producing the weapons.
At the beginning of the Apollo program, Kraft retired as a flight director to concentrate on management and mission planning. In 1972, he became director of the Manned Spacecraft Center (later Johnson Space Center), following in the footsteps of his mentor Robert R. Gilruth. He held the position until his 1982 retirement from NASA. During his retirement, Kraft has consulted for numerous companies including IBM and Rockwell International, and he published an autobiography entitled Flight: My Life in Mission Control.
More than any other person, Kraft was responsible for shaping the organization and culture of NASA's Mission Control. As his protégé Glynn Lunney commented, "the Control Center today ... is a reflection of Chris Kraft." When Kraft received the National Space Trophy from the Rotary Club in 1999, the organization described him as "a driving force in the U.S. human space flight program from its beginnings to the Space Shuttle era, a man whose accomplishments have become legendary."
