Lyndon B. Johnson taking the U.S. Presidential Oath of Office on Air Force One following the assassination of John F. Kennedy in Dallas on November 22, 1963. He was sworn in by Judge Sarah T. Hughes, making him the first President sworn in by a woman. Johnson was not sworn using a Bible; none could be found aboard the plane. A Roman Catholic Missal was discovered in Kennedy's desk, and this book was used during the swearing-in ceremony.
