North American Aviation production test pilot George Franklin Smith with a North American F-100A Super Sabre (NASM)

26 February 1955: Although it was his day off, North American Aviation production test pilot George Franklin Smith stopped by the office at Los Angeles Airport (today, known as Los Angeles International airport, or simply “LAX”, its FAA airport identifier). The company’s flight  dispatcher told him that a brand-new F-100A-20-NA Super Sabre, serial number 53-1659, was sitting on the flight line and needed to be test flown before being turned over to the Air Force.

Smith was happy to take the flight. He departed LAX in full afterburner and headed off shore, climbing to 35,000 feet (10,668 meters) over the Pacific Ocean to start the test sequence.

A North American F-100A-1-NA Super Sabre, 52-5757 (the second production airplane) takes off at Los Angeles International Airport. (This airplane, flown by NAA test pilot Bob Hoover, crashed east of Palmdale, California, 7 July 1955, when he could not recover from a flat spin. Hoover safely ejected but the Super Sabre was destroyed.) (North American Aviation, Inc.)

But it was quickly apparent that something was wrong: The flight controls were heavy, and then there was a hydraulic system failure that caused the Super Sabre pitch down into a dive. Smith couldn’t pull it out of the dive and the airplane’s speed rapidly increased, eventually passing Mach 1.

Smith was unable to regain control of the F-100. He had no choice but to bail out. As he ejected, Smith read the instruments: the Mach meter indicated Mach 1.05—785 miles per hour (1,263 kilometers per hour)—and the altitude was only 6,500 feet (1,981 meters).

The force of the wind blast hitting him as he came out of the cockpit knocked him unconscious. Estimates are that he was subjected to a 40 G deceleration. His parachute opened automatically and he came down approximately one-half mile off Laguna Beach. Fortunately he hit the water very close to a fishing boat crewed by a former U.S. Navy rescue expert.

The F-100 dived into the Pacific Ocean approximately ¼-mile (0.4 kilometers) offshore between Dana Point and Laguna Beach.

George Smith was unconscious for six days, and when he awoke he was blind in both eyes. After four surgeries and seven months in the hospital, he recovered from his supersonic ejection and returned to flight status.

George F. Smith appears in this brief U.S. Air Force informational film:

The North American Aviation F-100 Super Sabre was designed as a supersonic day fighter. Initially intended as an improved F-86D and F-86E, it soon developed into an almost completely new airplane. The fuselage incorporated the “area rule,” a narrowing in the fuselage width at the wings to increase transonic performance, similar to the Convair F-102A.

The Super Sabre had a 49° 2′ sweep to the leading edges of the wings and horizontal stabilizer. The ailerons were placed inboard on the wings and there were no flaps, resulting in a high stall speed in landing configuration. The horizontal stabilizer was moved to the bottom of the fuselage to keep it out of the turbulence created by the wings at high angles of attack. The F-100A had longer wings and a distinctively shorter vertical fin than the YF-100A. The upper segment of the vertical fin was swept 49° 43′.

There were two service test prototypes, designated YF-100A, followed by the production F-100A series. The first ten production aircraft (all of the Block 1 variants) were used in the flight testing program.

The F-100A Super Sabre was 47 feet, 1¼ inches (14.357 meters) long with a wingspan of 36 feet, 6 inches (11.125 meters). With the shorter vertical fin than the YF-100A, the initial F-100As had an overall height of 13 feet, 4 inches (4.064 meters), 11 inches (27.9 centimeters) less than the YF-100A.

The F-100A had an empty weight of 18,135 pounds (8,226 kilograms), and gross weight of 28,899 pounds (13,108 kilograms). Maximum takeoff weight was 35,600 pounds (16,148 kilograms). It had an internal fuel capacity of 755 gallons (2,858 liters) and could carry two 275 gallon (1,041 liter) external fuel tanks.

Following North American Aviation test pilot George Welch’s fatal accident, 12 October 1954, NACA designed a new vertical fin for the F-100A. It was taller but also had a longer chord. This resulted in a 10% increase in area. (NASA E-1573)

The early F-100As were powered by a Pratt & Whitney Turbo Wasp J57-P-7 afterburning turbojet engine. It was rated at 9,700 pounds of thrust (43.148 kilonewtons) for takeoff, and 14,800 pounds (65.834 kilonewtons) with afterburner. Later production aircraft used a J57-P-39 engine. The J57 was a two-spool axial flow turbojet which had a 16-stage compressor, and a 3-stage turbine. (Both had high- and low-pressure stages.) The engine was 15 feet, 3.5 inches (4.661 meters) long, 3 feet, 5.0 inches (1.041 meters) in diameter, and weighed 4,390 pounds (1,991 kilograms).

Test Pilot A. Scott Crossfield flew this F-100A-5-NA, 52-5778, in flight testing at the NACA High Speed Flight Station, October–December 1954. (NASA)

The Super Sabre was the first U.S. Air Force fighter capable of supersonic speed in level flight. It could reach 760 miles per hour (1,223 kilometers) at Sea Level. (Mach 1 is 761.1 miles per hour, 1,224.9 kilometers per hour, under standard atmospheric conditions.) Its maximum speed was 852 miles per hour (1,371 kilometers per hour) at 35,000 feet (10,668 meters)—Mach 1.29. The service ceiling was 44,900 feet (13,686 meters). Maximum range with external fuel was 1,489 miles (2,396 kilometers).

The F-100 was armed with four M-39 20 mm autocannons, capable of firing at a rate of 1,500 rounds per minute. The ammunition capacity of the F-100 was 200 rounds per gun.

North American Aviation built 199 F-100A Super Sabres at its Inglewood, California, plant before production shifted to the F-100C fighter bomber variant. Approximately 25% of all F-100As were lost in accidents.

This is the fifth production F-100A-1-NA Super Sabre, 52-5760, in flight southeast of San Bernardino, California. In this photograph, FW-760 has the taller vertical fin that was designed to improve the Super Sabre’s controllability. (U.S. Air Force)

25 February 1975: At Edwards Air Force Base, California,  Brigadier General Charles Elwood (“Chuck”) Yeager, United States Air Force, made his final flight as an active duty Air Force pilot, flying a McDonnell Douglas F-4E Phantom II 65-0713.¹

Brigadier General Charles E. Yeager made his final flight in the U.S Air Force in the prototype McDonnell YF-4E Phantom II 65-0713.

During his career, General Yeager flew 180 different aircraft types and accumulated 10,131.6 flight hours.

General Yeager retired 1 March 1975 after 12,222 days of military service.

McDonnell YF-4E Phantom II 65-0713 was named Glamorous Glennis for General Yeager’s Final Flight.

¹ 65-0713 was a McDonnell F-45D-28-MC Phantom II which had been modified as the prototype YF-4E, armed with an M61 rotary cannon. Later, 65-0713 was used as a test bed for the F-4G Wild Weasel. The airplane is on display at Edwards Air Force Base.

25 February 1965: At 11:26 a.m., Pacific Standard Time, the first Douglas DC-9 twin-engine airliner, serial number 45695, with Federal Aviation Administration registration mark N9DC, took off from Long Beach Airport (LGB), on the coast of Southern California, on its first flight. In the cockpit were Chief Engineering Test Pilot George R. Jansen, DC-9 Program Test Pilot Paul H. Patten, and Flight Test Engineer Duncan Walker.

The duration of the first flight was 2 hours, 13 minutes. N9DC landed at Edwards Air Force Base (EDW) where the test program would continue.

The Douglas DC-9 is a short-to-medium range twin-engine airliner, operated by a flight crew of two pilots. It was designed to carry up to 109 passengers. The initial production model is retroactively identified as the DC-9-10. This variant is 104 feet, 4¾ inches (31.820 meters) long with a wingspan of 89 feet, 5 inches (27.254 meters) and overall height of 27 feet, 6 inches (8.382 meters). The airliner has an empty weight of 49,020 pounds (22,235 kilograms) and maximum takeoff weight of 90,700 pounds (41,141 kilograms).

The DC-9-10 was powered by two Pratt & Whitney JT8D-5 turbofan engines, producing 12,250 pounds of thrust (54.49 kilonewtons), each. The JT8D was a two-spool engine with a 2-stage fan section, 13-stage compressor (6 low- and 7 high-pressure stages), nine combustion chambers and a 4-stage turbine (1 high- and 3 low-pressure stages). The JT8D-5 was 3 feet, 6.5 inches (1.080 meters) in diameter, 10 feet, 3.5 inches (3.137 meters) long, and weighed 3,096 pounds (1,404 kilograms).

The airliner had a cruise speed of 490 knots (564 miles per hour, 907 kilometers per hour) at 25,000 feet (7,620 meters). It has a range of 1,590 nautical miles (1,830 miles, 2,945 kilometers).

Delta Airlines was the lead customer for the Douglas DC-9. Delta’s first DC-9, serial number 45699, F.A.A. registration N3304L, was delivered in a ceremony at the Douglas plant at Long Beach Airport, 7 October 1965. Using a bottle containing water from twenty rivers in Delta’s area of operations, Stewardess Carol Marie Koberlein christened the airplane Delta Prince. Later that day it was flown to Atlanta by Delta’s legendary Captain Thomas Prioleau Ball, the airline’s Director of Flight Operations. The duration of the flight was 4 hours, 19 minutes.

After the flight test and certification program was over, 45695 was leased to Trans Texas Airways and re-registered N1301T. It served with Trans Texas from 1966 to 1982, when the airline merged with Continental Airlines. It retained the same N-number but was named City of Denver.

In 1983 49695 was sold to Sunworld International Airlines, a Las Vegas, Nevada charter company. After five years it was sold to another charter airline, Emerald Airlines of Dallas, Texas. In 1990, Emerald sold the DC-9 to Canafrica Transportes Aereos, based in Madrid, Spain. While operating for that company, 45695 was registered EC-622 and EC-FCQ. Returning to the United States in 1991, it was briefly owned by Viscount Air Service, Tucson, Arizona, registered N914LF.

Now 25 years old, ownership of the first DC-9 returned to the McDonnell Douglas Corporation. It was placed in storage at North Texas Regional Airport (GYI), Sherman, Texas, in 1992 and was used as a source for parts.

The Douglas DC-9 was produced in five civil variants, the DC-9-10 through DC-9-50. 41 were produced for the U.S. military, designated C-9A, C-9B and VC-9C. Production closed in 1982 after 976 aircraft had been built.

25 February 1927: Acting on behalf of a syndicate of St. Louis business men, Charles A. Lindbergh contracts Ryan Airlines Company of San Diego to design and build a single-engine monoplane for a flight from New York to Paris. This would become the Spirit of St. Louis. The cost is $10,580.

Lindbergh wrote:

“The Ryan Airlines factory is in an old, dilapidated building near the waterfront. I feel conspicuous driving up to it in a taxicab. A couple of loafers stare at me as I pay my fare. There’s no flying field, no hangar, no sound of engines warming up; and the unmistakable smell of dead fish from a near-by cannery mixes with the banana odor of dope from drying wings. . .

“I open the door to a small, dusty, paper-strewn office. A slender young man advances to meet me—clear, piercing eyes, intent face. He introduces himself as Donald Hall, chief engineer for Ryan Airlines, Incorporated. . . .”

—The Spirit of St. Louis, by Charles A. Lindbergh, Charles Scribner’s Sons, New York, 1953, Chapter III, Page 79.

“I check the wording and hand my telegram to the girl in the office. I’m ready to cast my lot with the Ryan organization. I believe in Hall’s ability; I like Mahoney’s enthusiasm. I have confidence in the character of the workmen I’ve met. This company is a fit partner for our organization in St. Louis. They’re as anxious to build a plane that will fly to Paris as I am to fly it there.”

24 February 2011, 21:53:24 UTC: Space Shuttle Discovery (OV-103) is launched on its final mission, STS-133. The mission was to dock the Leonardo Permanent Multipurpose Module at the International Space Station, as well as to transport other sensors, materials and supplies. The launch had been “scrubbed” five times since 29 October 2010.

Mission STS-133 was commanded by Colonel Steven Wayne Lindsey, United States Air Force. This was Colonel Lindsey’s fifth space shuttle flight. The shuttle pilot was Colonel Eric Allen Boe, U.S. Air Force. There were four Mission Specialists aboard: Nicole Marie Passonno Stott, a structural engineer; Colonel Benjamin Alvin Drew, U.S. Air Force; Michael Reed Barratt, M.D., a NASA Aviation Medical Examiner (“flight surgeon”); and Captain Stephen Gerard Bowen, U.S. Navy.

Discovery docked at the International Space Station at 19:14 UTC, 26 February. Equipment and supplies were transferred.

Leonardo, which had previously been docked at the space station from March 2001 until April 2010, when it was returned to Earth to be modified and upgraded, was installed on the ISS on 1 March. Discovery remained docked at ISS for 8 days, 16 hours, 46 minutes.

The space shuttle returned to Earth on 9 March, landing at the Kennedy Shuttle Landing Facility at 16:58:14 UTC. The total duration of the mission was 12 days, 19 hours, 4 minutes, 50 seconds.

Discovery is the space shuttle fleet leader, having made 39 orbital flights, more than any other shuttle. It has spent 365 days, 22 hours, 39 minutes, 33 seconds in space flight, traveling 148,221,675 miles (238,539,663 kilometers).

On 19 April 2012, Discovery was placed on display at the Steven F. Udvar-Hazy Center of the Smithsonian Institution National Air and Space Museum.
