Frank Frederick Borman, II was born on March 14, 1928, in Gary, Indiana. He is of German descent, born as the first and only child to parents Edwin and Marjorie Borman. Because he suffered from numerous sinus problems in the cold and damp weather, his father packed up the family and moved to the better climate of Tucson, Arizona, which Borman considers his home town. He started to fly at the age of 15.
Perhaps the most significant point about the lunar-orbit flight proposed for Apollo 8 was that the command and service modules would fly the same route to the moon as would be used for the actual lunar landing.
