The Smithsonian Institution's National Air and Space Museum (NASM) maintains the largest collection of historic air and spacecraft in the world. It is also a vital center for research into the history, science, and technology of aviation and space flight.

The Museum has two display facilities. The flagship building on the National Mall in Washington, D.C. has hundreds of artifacts on display including the original Wright 1903 Flyer, the "Spirit of St. Louis," Apollo 11 command module, and a Lunar rock sample that visitors can touch. The new Steven F. Udvar-Hazy Center displays many more artifacts including the Lockheed SR-71 "Blackbird", Boeing B-29 Superfortress "Enola Gay" and Space Shuttle "Enterprise". The museum continues to develop new exhibits to examine the impact of air and space technology on science and society.

Of all the Presidents of the United States, George Washington is the most celebrated. Efforts to commemorate his legacy began during his lifetime and continue to this day. Down through the years they have taken on many forms. His leadership and service to the republic have been distinguished through the naming of the federal capital, universities, streets, counties, and a state. In addition to these honors, he had been remembered in works of art, monumental buildings, and historic preservation, involving Americans of all walks of life. But none have captured the imagination of the people world-wide like the Washington Monument.

June 25, 1950 the 38th Parallel marked the beginning of a war that was to be like no other. Many years have passed since the end of the Chosin Reservoir Campaign in North Korea. The American public has all but forgotten the violence and valor that took place there at the fighting man's level. The fiftieth anniversary of the Korean War gives both the armed forces and the nation an opportunity to honor those veterans who served in that bitter war. The battle continues along the present demilitarized zone. The location of this line largely above the 38th Parallel is historic evidence that in Korea, aggression did not pay.
