Craig Collins' new book, "Midair," tells the story of his uncle and pilot Don Harten, who experienced a B-52 collision while flying over the South China Sea.
Major Harten began his military career in 1964 flying B-52s in the Mather Air Force Base.
During the Vietnam War, Harten was to be deployed Feb. 11, 1965 on a secretive mission to take out an airfield in Hanoi near Phuc Yen, but was cancelled by President Lyndon Johnson the hour before commencing.
Collins recalls more of his conversation with his uncle Harten to the moments leading up to that crash in midair.
