When Lyndon Baines Johnson wanted to go somewhere, there was no stopping him. This dynamic president called for Air Force One as others summon a taxi - at a moment's notice, whatever the hour or the weather. And the man who made sure that LBJ got his ride was General James U. Cross, the president's hand-picked pilot, top military assistant, and personal confidante. The only Air Force One pilot to have a position, simultaneously, in the White House, General Cross is also the only member of LBJ's inner circle who has not publicly offered his recollections of the president. Until now.
