For the inauguration twenty-seven people squeezed into the sixteen-foot square stateroom of Air Force One for the proceedings. Adding to the discomfort was the lack of air conditioning as the aircraft had been disconnected from the external power supply, in order to take off promptly. As the inauguration proceeded the four jet engines of Air Force One were being powered up.
The Warren Commission’s report detailed the inauguration: “From the Presidential airplane, the new President telephoned Attorney General Robert F. Kennedy, who advised that Mr. Johnson take the Presidential oath of office before the plane left Dallas. Federal Judge Sarah T. Hughes hastened to the plane to administer the oath. Members of the Presidential and Vice-Presidential parties filled the central compartment of the plane to witness the swearing in. At 2:38 p.m. CST, Lyndon Baines Johnson took the oath of office as the 36th President of the United States. Mrs. Kennedy and Mrs. Johnson stood at the side of the new President as he took the oath of office. Nine minutes later, the Presidential airplane departed for Washington, D.C.”
The swearing-in ceremony administered by Judge Hughes in an Air Force One conference room represented the first time that a woman administered the presidential oath of office as well as the only time it was conducted on an airplane. Instead of the usual Bible, Johnson was sworn in upon a missal found on a side table in Kennedy’s Air Force One bedroom. After the oath had been taken, Johnson kissed his wife on the forehead. Mrs. Johnson then took Jackie Kennedy’s hand and told her, “The whole nation mourns your husband”.
The famous photograph of the inauguration was taken by Cecil Stoughton, John F. Kennedy’s official photographer. On Stoughton’s suggestion Johnson was flanked by his wife and Jacqueline Kennedy, facing slightly away from the camera so that blood stains on her pink Chanel suit would not be visible. The photograph was taken using a Hasselblad camera.
