16 November 2004: Balls 8, the Boeing NB-52B “mothership” at the NASA Dryden Flight Research Center (located at Edwards Air Force Base, California) performs a farewell flyover during its final flight. 52-008 was both the oldest airplane in the U.S. Air Force inventory and the lowest time B-52 Stratofortress still operational.
Boeing RB-52B-10-BO Stratofortress 52-008 was built at Seattle, Washington and made its first flight 11 June 1955. It was turned over to NASA 8 June 1959 for use as a air launch vehicle for the X-15 rocketplane. North American Aviation modified the bomber for its new role at Air Force Plant 42, Palmdale, California. It was redesignated NB-52B.

16 November 1973: Skylab 4 lifted off from Launch Complex 39B, Kennedy Space Center, at 14:01:23 UTC. Aboard the Apollo Command and Service Module were NASA astronauts Lieutenant Colonel Gerald Paul Carr, U.S. Marine Corps, Mission Commander; Lieutenant Colonel William Reid Pogue, U.S. Air Force; and Edward George Gibson, Ph.D. This would be the only space mission for each of them. They would spend 84 days working aboard Skylab.

The S-IB was built by Chrysler Corporation Space Division at the Michoud Assembly Facility near New Orleans, Louisiana. It was powered by eight Rocketdyne H-1 engines, burning RP-1 and liquid oxygen. Eight Redstone rocket fuel tanks, with 4 containing the RP-1 fuel, and 4 filled with liquid oxygen, surrounded a Jupiter rocket fuel tank containing liquid oxygen. Total thrust of the S-IB stage was 1,666,460 pounds (7,417.783 kilonewtons) and it carried sufficient propellant for a maximum 4 minutes, 22.57 seconds of burn. First stage separation was planned for n altitude of 193,605 feet, with the vehicle accelerating through 7,591.20 feet per second (2,313.80 meters per second).
The McDonnell Douglas Astronautics Co. S-IVB stage was built at Huntington Beach, California. It was powered by one Rocketdyne J-2 engine, fueled by liquid hydrogen and liquid oxygen. The J-2 produced 229,714 pounds of thrust (1,021.819 kilonewtons), at high thrust, and 198,047 pounds (880.957 kilonewtons) at low thrust). The second stage carried enough fuel for 7 minutes, 49.50 seconds burn at high thrust. Orbital insertion would be occur 9 minutes, 51.9 seconds after launch, at an altitude of 98.5 miles (158.5 kilometers) with a velocity of 25,705.77 feet per second (7,835.12 meters per second).
The Skylab-configuration Saturn IB rocket was 223 feet, 5.9 inches (68.119 meters) tall. It had a maximum diameter of 22.8 feet (6.949 meters), and the span across the first stage guide fins was 40.7 feet (12.405 meters). Its empty weight was 159,000 pounds (72,122 kilograms) and at liftoff, it weighed 1,296,000 pounds (587,856 kilograms). It was capable of launching a 46,000 pound (20,865 kilogram) payload to Earth orbit.

16 November 1970: At the Lockheed California Company Plant 10, just north of Palmdale in the high desert of Southern California, test pilot Henry Baird (“Hank”) Dees, co-pilot Ralph C. Cokely (formerly a Boeing 747 test pilot), with flight test engineers Glenn E. Fisher and Rod Bray, took the new prototype Lockheed L-1011-1 TriStar, N1011, on its first flight.
During the 2½-hour test flight, the airliner reached 250 knots (288 miles per hour, 463 kilometers per hour) and 20,000 feet (6,096 meters).

The Lockheed L-1011 TriStar is a three-engine wide body airliner designed to carry up to 400 passengers on medium or long distance routes. It is operated by a flight crew of three. The prototype, the L-1011-1 and L-1011-200 production aircraft were 177 feet, 8½ inches (54.166 meters) long with a wingspan of 155 feet, 4 inches (47.346 meters). The longer range, higher gross weight L-1011-500 variant was 164 feet, 2½ inches (50.051 meters) long with a wingspan of 164 feet, 4 inches (50.089 meters). All TriStars have an overall height of 55 feet, 4 inches (16.866 meters). The interior cabin width is 18 feet, 11 inches (5.766 meters). Empty weight ranges from 241,700 pounds (109,633 kilograms) to 245,400 pounds (111,312 kilograms), while the maximum takeoff weight varies from 430,000 pounds (195,045 kilograms) to 510,000 pounds (231,332 kilograms).
The L-1011-1 aircraft were powered by three Rolls Royce RB.211-22B-02 high bypass turbofan engines, producing 42,000 pounds of thrust (186.825 kilonewtons). The -200 and -500 variants used the more powerful RB.211-524B4 which produces 53,000 pounds (235.756 kilonewtons). The RB.211-22 is a “triple-spool” axial-flow turbine engine. It has a single fan stage, 13-stage compressor (7 intermediate- and 6 high-pressure stages), single combustion chamber, and 5 stage turbine section (1 high-, 1 intermediate- and three low-pressure stages). The -22B is 10 feet, 11.4 inches (3.033 meters) long and its fan diameter is 7 feet, 0.8 inches (2.154 meters). It weighs 9,195 pounds (4,171 kilograms).

Depending on the model, the L-1011 series had a cruise speed of 520–525 knots (598–604 miles per hour, 963–972 kilometers per hour) and a maximum speed of 0.95 Mach. The service ceiling was 42,000–43,000 feet (12,802–13,106 meters). Maximum range for the long range -500 was 6,090 nautical miles (7,008 miles, 11,279 kilometers).

The Lockheed L-1011 TriStar was a very technologically advanced airliner for the time. It was the first to be certified for Category IIIc autolanding, in which the airplane’s automatic flight system could land the airplane in “zero-zero” weather conditions.
Lockheed built 250 L-1011s between 1970 and 1984. Sales were delayed because of problems with delivery of the Rolls-Royce turbofans, giving an early advantage to the competitor McDonnell DC-10, of which 446 were built.
Few TriStars remain in service. The prototype, N1011, was scrapped at Ardmore, Oklahoma, in August 1996. A portion of its fuselage, painted in Delta Air Lines livery, is on display at Atlanta-Hartsfield International Airport, Atlanta, Georgia.

Queensland and Northern Territories Aerial Services, Ltd., first airplane, an Avro 504K, G-AUBG. (Qantas)
16 November 1920: Queensland and Northern Territories Aerial Services, Ltd., today known as Qantas, is one of the oldest airlines in the world. It was founded at Winton, Queensland, Australia, on 16 November 1920 as Queensland and Northern Territory Aerial Services Limited by Paul Joseph McGinness, D.F.C., D.C.M., and Wilmot Hudson Fysh, D.F.C., both World War I fighter aces; Fergus McMaster, a local businessman; and Wilfred Arthur Baird, an aircraft mechanic who had served in Egypt with McGinness and Fysh.
Initially the airline operated air mail services which were subsidized by the Australian government, linking railheads in western Queensland. It flew its first commercial passenger, Alexander Kennedy, on 2 November 1922.
The airline’s first airplane was a two-place, single-engine A. V. Roe & Co., Ltd., Avro 504, c/n D1, G-AUBG. D1 was one of nine Avro 504-series airplanes which were assembled by the Australian Aircraft and Engineering Company, A. V. Roe’s licensee at Sydney, New South Wales. A replica of the airplane is on display at the Kingsford Smith Memorial, Mascot, New South Wales.
Qantas took delivery of D1 on 30 January 1921. It was assigned a registration mark of G-AUBG, 28 June 1921. The airplane was involved in a serious accident at Ingham, North Queensland, 2 August 1921. It was repaired and returned to service three months later.
Qantas operated it until 6 November 1926, when it was sold to H.J. Taylor, of Hawthorn, Victoria. The airplane was later owned by Matthews Aviation, and finally, by Newcastle Air Service, as Newcastle’s Own. The Avro’s registration was changed to VH-UBG, 28 March 1929. The registration was cancelled 14 April 1932.
Between 1913 and 1932, nearly 9,000 Avro 504-series airplanes were built by more than twenty manufacturers. The Avro 504K was 29 feet, 5 inches (8.996 meters) long with a wingspan of 36 feet (10.973 meters) and height of 10 feet, 5 inches (3.175 meters). Its empty weight was 1,231 pounds (558 kilograms) and the maximum takeoff weight was 1,829 pounds (830 kilograms).
The Avro 504 had been designed to accept installation of several different engines. D1 had been assembled using a water-cooled, normally-aspirated, 8.822 liter (538.351 cubic inches) Sunbeam-Coatalen Aircraft Engines Dyak single overhead camshaft (SOHC) inline 6-cylinder engine. (Sunbeam named its aircraft engines after ethnic groups. The Dyak are an indigenous people of Borneo.) The Sunbeam Dyak was a left-hand tractor, direct-drive engine with two valves per cylinder and a compression ratio of 5:1. It used two Claudel-Hobson B.Z.S. 38 updraft carburetors, two magnetos, and was rated at 100 horsepower at 1,200 r.p.m. The Dyak weighed 399 pounds (190 kilograms).
In 1931, the Avro was re-engined with a right-hand tractor, water-cooled, normally-aspirated, 9.005 liter (549.519 cubic inches) A.D.C. (Aircraft Disposal Company, or “Airdisco”) overhead valve (OHV) V-8 engine. The A.D.C. V-8 had a compression ratio of 4.6:1 and was rated at rated at 120 horsepower at 1,800 r.p.m. It had 2:1 propeller gear reduction.

The 504K had a cruise speed of 75 miles per hour (121 kilometers per hour), maximum speed of 90 miles per hour (145 kilometers per hour), service ceiling of 16,000 feet (4,877 meters) and range of 250 miles (402 kilometers).
As of October 2017, Qantas had 29,596 employees. After-tax profit for 2016 was A$1,029,000,000. Qantas currently operates a fleet of 118 aircraft, which includes 28 Airbus A330s and 12 A380s, 10 Boeing 747-400s, 67 B737-800s and 1 787-9. The airline has 45 Boeing 787-9 Dreamliners on order, with confirmed delivery dates for the first 15.
