First Air Force One Christened
On November 24, 1954, First Lady Mamie Eisenhower christened the first plane to be designated Air Force One.
Decades earlier, Theodore Roosevelt became the first US president to fly in an airplane. The flight came after his time as president, on October 11, 1910. On that occasion, he rode in an airplane piloted by Arch Hoxsey at a county fair in St. Louis.
