U.S. Air Force, North American X-10, experimental aircraft being towed by a tug, at Edwards Air Force Base, California, United States. Tow tug moves the aircraft in a circle, allowing views from all sides. Of particular note is lack of a cockpit (the aircraft is unmanned), and the presence of a canard at the nose of the aircraft. View of aircraft on takeoff roll, in nose high attitude, raising a dust cloud, as it accelerates. View of X-10, cruising aloft, with canard and landing gear retracted. The minimal delta wing is visible from below. The aircraft, in nose high attitude, with landing gear extended, in flight and then cleaned up and cruising, again.
A U.S. Air force F-100 Super sabre jet aircraft rounds out high in nose-high attitude, during attempted emergency landing at Edwards Air Force Base, California. The pilot applies power to go around without success as the F-100 enters a state known as a "Sabre Dance". The aircraft's right wing strikes the runway and it crashes on the runway in a ball of fire. (Note: This F-100 was being ferried from Palmdale, California, when it encountered problems, and the pilot elected to make an emegency landing at Edwards AFB)

The Santa Susana Mountains in Southern California. The Sodium Reactor Experiment nuclear power plant at the Santa Susana Field Laboratory near Simi Valley, California. Facilities inside the Sodium Reactor Experiment also known as the SRE. A miniature model of the SRE showing its sodium graphite reactor. Miniature pipes show the movement of liquid sodium into the reactor. Animation shows the core tank and the reactor fuel is metallic uranium contained in clusters suspended within the core of the reactor. The animation shows the layers of the core tank, the flow of liquid sodium into the core tank, and a diagram showing the transfer of energy from the core tank to steam plant that produces electricity.
