The Surveyor 7 landing site on the Moon 

On Tuesday, January 9, 1968, the Surveyor 7 space probe, the fifth and
final spacecraft of the Surveyor series, made a soft landing on the Moon,
marking the end of the American series of unmanned explorations of the
lunar surface. The primary objectives of the Surveyor program, a series
of seven robotic lunar soft landing flights, were to support the coming
manned Apollo landings. The Surveyor program had a total price tag
of $469 million.   

The United States issued its first commemorative stamp on January 2, 1893, the
$1 Columbian Exposition issue, "Isabella pledging her jewels", one of a set of 16 commemoratives issued to celebrate the 400th anniversary of Christopher
Columbus’s arrival in the New World in 1492.

William "Billy" Mitchell (December 29, 1879 – February 19, 1936)

Mitchell was one of the most famous and most controversial figures in the
history of American military aviation. He commanded American air combat
units in France during World War l and was appointed deputy director of 
the Air Service following the war. He believed that bombers should take
the place of battleships and there should be a separate command for the
Air Service.

Mitchell received many honors following his death, including a commission
by President Franklin Roosevelt as a Major General and was the only
person to have an American military aircraft, the B-25 bomber (below),
named after him.

The influence of air power on the ability of one nation to impress its will on
another in armed contest will be decisive.
