August 26, 1959 – The first VC-137 enters service. In 1943, President Franklin Delano Roosevelt became the first US President to fly on an airplane for official government business when he traveled to Casablanca on the Moroccan coast for a war strategy meeting with British Prime Minister Winston Churchill. President Roosevelt made the trip in a Boeing 314 flying boat named the Yankee Clipper. After the Boeing 314, Roosevelt flew in a Douglas VC-54C Skymaster named the Flying White House but popularly known as Sacred Cow, the first purpose-built presidential aircraft, when he went to the Yalta Conference, and his successor, President Harry S. Truman, used a Douglas DC-6 named Independence. President Dwight Eisenhower then flew in two different Lockheed VC-121 Constellations named Columbine II and Columbine III.

But as the world entered the jet age following WWII, and with the arrival of the Boeing 707, America’s first jet airliner, in 1958, it was clear to the Air Force that it was time for the President to transition to a jet-powered transport. In 1958, the Air Force accepted its first 707, dubbed the VC-137A, and it was given the designation Special Air Mission (SAM) 970 based on its serial number. Two more 707s were then added and were given the designations SAM 971 and SAM 972.

The new aircraft featured living and working spaces for the president and his staff, as well as modern communications equipment. President Eisenhower was the first US President to fly in the new airliner, visiting 11 Asian nations during his “Flight to Peace” goodwill tour in 1959. But the SAM jets used by Eisenhower, and briefly by his successor, John F. Kennedy, looked nothing like the iconic blue and white jets we see today. The original 707s featured a rather gaudy, bright red-orange nose and bright orange tail stripe. It wasn’t until the next generation of Boeing C-137 Stratoliners purchased for President Kennedy that the airliners decked out in the famous blue, white and silver livery designed by Raymond Loewy.

SAM 970 served Presidents Eisenhower, Kennedy and Lyndon Johnson and, after the original SAM 970 was replaced in 1962 by two newer VC-137Cs (SAM 26000 and SAM 27000), it continued flying VIPs and the Vice President until 1996, with its last executive passenger being Vice President Al Gore. SAM 970 is preserved and is on display at the Museum of Flight in Seattle, Washington, while SAM 971, a V137B, resides at the Pima Air and Space Museum in Arizona. SAM 972 was scrapped in 1996.

August 27, 1990 – The first flight of the Northrop YF-23. In war, control of the airspace over the battlefield is of paramount importance and, by the 1980s, the US Air Force needed to counter the latest generation of Russian fighters such as the Sukhoi Su-27 and Mikoyan Gurevich MiG-29. The Air Force issued requirements for a new air superiority fighter that would take advantage of developments in new construction materials, engines that could provide super cruise and vectored thrust, and, perhaps most importantly, the latest developments in stealth technology. While stealth doesn’t make an aircraft invisible, it does reduce its radar signature so that it can be difficult to detect, and stealth technology was first demonstrated brilliantly by the Lockheed F-117 Nighthawk.

In 1981, the year that the F-117 took its maiden flight (though designated as a fighter, the Nighthawk is truly a tactical bomber), the Air Force initiated its Advanced Tactical Fighter (ATF) program to find a replacement for the McDonnell Douglas F-15 Eagle in the air superiority role. Two groups of manufacturers—Lockheed/Boeing/General Dynamics and Northrop/McDonnell Douglas—paired with Pratt & Whitney and General Electric to produce two prototype aircraft each. The Lockheed-led group proposed the YF-22, which incorporated stealth capability along with thrust-vectoring engines for increased maneuverability. The Northrop-led group offered the YF-23 Black Widow II (the second prototype was dubbed Gray Ghost due to its lighter paint scheme). The Northrop proposal placed greater emphasis on stealthy design but saved weight and complexity by eliminating thrust-vectoring. The YF-23 also made extensive use of the area rule to reduce drag at transonic speeds. The first YF-23 was powered by a pair of Pratt & Whitney YF119 afterburning turbofans, while the second received General Electric YF120 engines. To increase the stealthiness of the fighter, the exhaust from the engines was routed through troughs lined with materials to reduce the aircraft’s heat signature.

Both aircraft underwent four years of testing and competition, during which the YF-23 proved to be stealthier and faster than the YF-22. The YF-22, with its vectored thrust, proved to be more agile. On April 23, 1991, the Air Force announced that the Lockheed design was the winner, and the YF-22 entered production as the F-22 Raptor in 1996. Both YF-23 prototypes were sent to NASA for use as test beds, but they were never flown again. Some consideration was given to having Northrop develop a carrier-based version of the YF-23 for the US Navy, or an interim bomber version for the Air Force, but those plans never came to fruition. The first prototype is now housed at the National Museum of the United States Air Force in Ohio, and the second is on display at the Western Museum of Flight in California.

August 25, 2012 – The death of Neil Armstrong, an aerospace engineer, combat pilot, test pilot, astronaut, and the first human being to set foot on the Moon. Armstrong was born on August 5, 1930 in Wapakoneta, Ohio. After serving as a fighter pilot in Korea, he received a degree in engineering from Purdue University. Following a stint as a test pilot, Armstrong joined the NASA Astronaut Corps in 1962 and became the first American civilian to fly in space when he served as command pilot for Gemini 8. His second and final spaceflight took place in July 1969 when he commanded Apollo 11 and put the first human footprint on the Moon. Armstrong retired from NASA following that flight, and became a college professor and businessman before his death at age 82.

August 25, 1995 – The first flight of the Airbus A319, a narrow-body, short-to-medium-range airliner that was developed from the Airbus A320. A shorter version of the A320, the A319 was developed based on a request by Steven F. Udvar-Házy of International Lease Finance Corporation (IFLC) and was intended to provide direct competition to the Boeing 737. Though it carries slightly fewer passengers than the A320, it has the same fuel capacity, thus the range is extended up to 3,700 nautical miles with the addition winglets (called Sharklets by Airbus). Just under 1,500 A319s have been produced, and it is in service with over 100 operators worldwide.

August 26, 2012 – Ron Akana retires as the longest-serving flight attendant in history. Born in 1928 in Honolulu, Hawai’i, Akana responded to an advertisement placed by United Airlines in 1949 to fill a steward position. A college student at the time, Akana said that his main reason for joining United was the opportunity to fly to the mainland. His first flight on a Boeing 377 Stratocruiser began a 63-year run of service, with only a two-year interruption from 1950-1951 to serve in the Korean War. After spending his entire career with United, Akana retired after a flight from Denver to Kauai having logged 200 million airmiles and having crossed the Pacific Ocean 10,000 times.

August 26, 2002 – The first flight of the Eclipse 500, a small, six-seat business jet and the first in a new class of Very Light Jet (VLJ). Previously called microjets, VLJs are approved for single-pilot operation and seat four to eight passengers with a maximum take-off weight (MTOW) of under 10,000 pounds. The Eclipse 500 is based on the Williams V-Jet II which was designed by Burt Rutan and is powered by a pair of Pratt & Whitney Canada PW610F turbofans that give it a maximum speed of 425 mph and a range of nearly 1,300 miles. Eclipse Aviation entered bankruptcy in 2008 due to a lack of funding, and production stopped at 560 aircraft. After liquidation, Eclipse Aerospace took over, and development of a more advanced Eclipse 550 is underway.

August 26, 1975 – The first flight of the McDonnell Douglas YC-15, an unsuccessful entrant into the US Air Force competition to procure a jet-powered replacement for the Lockheed C-130 Hercules. McDonnell Douglas competed against the Boeing YC-14 for the Air Force contract, but neither aircraft was selected. The YC-15 featured advances such as a supercritical wing to reduce drag and increase lift, along with externally blown flaps to improve low-speed performance. Only two YC-15 prototypes were built and, while it failed to enter production, many elements of its design served as the basis for the Boeing C-17 Globemaster III following McDonnell Douglas’ merger with Boeing in 1997.

August 27, 1990 – Blues guitatist Stevie Ray Vaughan is killed in a helicopter crash. Following a performance with Eric Clapton in East Troy, Wisconsin, Vaughan and members of his band boarded four helicopters to take them to Chicago’s Meigs Field. Along with three members of Clapton’s entourage, Vaughan boarded a Bell 206B JetRanger, and the pilot took off despite haze, fog and low clouds in the area. The flight path required the pilot to fly over a 1,000-foot high ski hill, but the helicopter struck the hill approximately 50 feet from the summit, killing all on board. The National Transportation Safety Board cited pilot error as the cause of the crash, and listed weather conditions as a contributing factor.

August 27, 1940 – The first flight of the Caproni Campini N.1, an experimental aircraft powered by a mortorjet, a precursor to the modern jet engine. The N.1 was incorrectly credited by the Fédération Aéronautique Internationale (FAI) as the first jet-powered aircraft to take flight, as news of an earlier flight by the Heinkel He 178 had not been widely reported. However, the N.1 was not a true jet, as it used a standard aircraft engine to turn the compressor in an arrangement Caproni called a “thermojet.” Two prototypes were built, and one is on display at the Italian Air Force Museum near Rome.

August 27, 1939 – The first flight of the Heinkel He 178, the world’s first practical turbojet-powered aircraft. The engine was developed by Hans von Ohain at the same time as, but separate from, work being done in England by Frank Whittle, and was first demonstrated in 1937. Heinkel received little support for his private venture from the German Air Ministry, as they were focused on development of traditional piston engines being made by BMW and Junkers. The He 178 featured a metal fuselage with high-mounted wooden wings and retractable landing gear, though the gear remained fixed during flight tests. Despite the promise of the new powerplant, only one airframe was built by Heinkel, and it was destroyed in an Allied air raid in 1943.

August 28, 1988 – Three aircraft from the Italian Air Force demonstration team Frecce Tricolori crash during an air show at Ramstein Air Force Base. During the Flugtag 88 air show, ten Italian Aermacchi MB-399 PAN trainer aircraft were performing a “pierced heart” maneuver in which two crossing groups of aircraft are split by a single aircraft flying a perpendicular course towards the crowd. As the planes crossed, the solo aircraft struck two others in the formation, raining debris and burning fuel onto the audience below. Sixty-seven spectators were killed, along with the three Italian pilots, and 346 were injured. Germany declared a three-year moratorium on public air shows, and new rules were put in place dictating greater viewing distances and banning maneuvers that were directed towards the crowd. News reports of the disaster can be seen here.
