10 November 1995: Captain Suzanna Darcy-Henneman set a Fédération Aéronautique Internationale (FAI) world record for distance flown by a commercial aircraft when she and a crew of 7 additional pilots flew a Boeing 777-200LR Worldliner, N6066Z, non-stop from Hong Kong (HKG) to London Heathrow (LHR), a distance of 21,601.33 kilometers (13422.44 miles), in 22 hours, 22 minutes.¹ During the flight, Captain Darcy-Henneman also set two speed records. The 777 averaged 981.57 kilometers per hour (609.92 miles per hour) from Los Angeles to New York,² and 910.54 kilometers per hour (565.78 miles per hour) from New York to London.³
Suzanna Darcy joined Boeing’s engineering department in 1974. She learned to fly with the Boeing Employees Flying Association. Darcy graduated from the University of Washington in 1981 with a Bachelor of Science degree in Aeronautics and Aeronautical Engineering. She then became a ground school instructor for Boeing’s Model 757 and 767 airliners.
In 1985, Boeing assigned Darcy-Hanneman as a production test pilot, the first woman to hold that position with the company. She was also the first woman to earn a captain’s rating on the 747-400, and is also rated on the 737, 757, 767 and 777. She performed flight testing on the 737-300 and was the project test pilot for the 777-200LR.
In 2008, Captain Darcy-Hanneman became Chief Pilot, Boeing Commercial Airplane Services. She is a member of the Society of Experimental Test Pilots, and was inducted into the Women in Aviation Pioneer Hall of Fame in 2010. She retired from Boeing in 2015.
The Boeing 777-200LR was designed for very long distance airline routes. It is operated by two pilots, and can carry a maximum 317 passengers. The airplane is 209 feet, 1 inch (63.729 meters) long with a wingspan of 212 feet, 7 inches (64.795 meters) and overall height of 61 feet, 1 inch (18.618 meters). It has an empty weight of 320,000 pounds (145,150 kilograms), and maximum takeoff weight of 766,000 pounds (347,452 kilograms).
The 777-200LR is powered by two General Electric GE-90-110B1 or -115B engines. The engine is dual rotor axial-flow high bypass turbofan. It has a single fan stage; 4-stage high pressure- and 9-stage low pressure compressor section; with a 2-stage high- and 6-stage low-pressure turbine. The high pressure rotor turns 9,332 r.p.m., and the low-pressure rotor turns 2,355 r.p.m. The engine is 286.67 inches (7.281 meters) long and weighs 19,316 pounds (8,761.590 kilograms). The fan has a diameter of 128 inches (3.251 meters). The GE90-115 produces a maximum 115,300 pounds of thrust (156.326 kilonewtons).
The 777-200LR has a maximum speed (MMO) of 0.89 Mach. Its maximum operating altitude is 43,100 feet (13,137 meters).
As of September 2020, Boeing had delivered sixty 777-200LRs.
16 October 1963: Operation Greased Lightning. Major Sidney J. Kubesch, Major John Barrett and Captain Gerard Williamson flew from Tokyo, Japan, to London England, non-stop, in 8 hours, 35 minutes, 20.4 seconds. Their airplane was a Convair B-58A-20-CF Hustler, serial number 61-2059, named Greased Lightning. It was assigned to the 305th Bombardment Wing, 19th Air Division, at Bunker Hill Air Force Base, Indiana.
Five inflight refuelings were required to complete the flight. The bomber had to slow from its supersonic cruise to rendezvous with the tankers. The B-58’s average speed was 692.71 miles per hour (1,114.81 kilometers per hour). The time from Tokyo to Anchorage, Alaska was 3 hours, 9 minutes, 42 seconds at an average speed of 1,093.4 miles per hour (1,759.7 kilometers per hour); and Anchorage to London, 5 hours, 24 minutes, 54 seconds at 826.9 miles per hour (1.330.8 kilometers per hour).
Greased Lightning‘s speed record still stands.
The three crewmen were awarded the Distinguished Flying Cross.
The B-58 Hustler was a high-altitude Mach 2 strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator located in individual cockpits. The aircraft is a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors.
The Hustler is 96 feet, 10 inches (29.515 meters) long, with a wing span of 56 feet, 10 inches (17.323 meters) and an overall height of 31 feet 5 inches (9.576 meters). The wing’s leading edge is swept back at a 60° angle and the fuselage incorporates the “area rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder, and there are no flaps.
The B-58A was powered by four General Electric J79-GE-5 axial-flow afterburning turbojet engines, suspended under the wings from pylons. This was a single-shaft engine with a 17-stage compressor and 3-stage turbine, rated at 10,300 pounds of thrust (45.82 kilonewtons), and 15,600 pounds (69.39 kilonewtons) with afterburner. The J79-GE-5 was 16 feet, 10.2 inches (5.136 meters) long and 3 feet, 2.0 inches (0.965 meters) in diameter.
The bomber had a cruise speed of 610 miles per hour (981.7 kilometers per hour) and a maximum speed of 1,325 miles per hour (2,132.4 kilometers per hour). The service ceiling is 64,800 feet (19,751 meters). Unrefueled range is 4,400 miles (7,081 kilometers). Maximum weight is 168,000 pounds (76,203.5 kilograms).
The B-58 weapons load was a combination of a W-39 warhead, and/or Mk.43 or B61 nuclear bombs. The W-39 warhead, the same used with the Redstone IRBM or Snark cruise missile, was carried in a jettisonable centerline pod, which also carried fuel for the aircraft. The smaller bombs were carried on underwing hardpoints. For defense, there was a General Electric M61 Vulcan 20×102 mm six-barreled rotary cannon mounted in the tail, with 1,200 rounds of linked ammunition, controlled by the Defensive Systems Officer.
Convair B-58A-20 CF 61-2059 is in the collection of the Strategic Air and Space Museum, Ashland, Nebraska.
16–17 August 1989: On its delivery flight, Qantas’ first Boeing 747-438 Longreach airliner, VH-OJA, City of Canberra, was flown by Captain David Massey-Green from London Heathrow Airport, England (IATA: LHR, ICAO: EGLL) to Sydney Kingsford Smith Airport, Australia (IATA: SYD, ICAO: YSSY), non-stop. Three other senior Qantas captains, Ray Heiniger, George Lindeman and Rob Greenop completed the flight deck crew. Boeing Training Captain Chet Chester was also aboard.
The distance flown by the new 747 was 17,039.00 kilometers (10,587.54 miles) at an average speed of 845.58 kilometers per hour (525.42 miles per hour). The flight’s duration was 20 hours, 9 minutes, 5 seconds. This set a new Fédération Aéronautique Internationale (FAI) World Record for Distance ¹ and World Record for Speed Over a Recognized Course.²
VH-OJA was the first of four Boeing 747-400 airliners ordered by Qantas more than two years earlier. The company named these “Longreach” both to emphasize their very long range capabilities, but also as a commemoration of the first scheduled passenger flight of the Queensland and Northern Territories Aerial Services Ltd. at Longreach, Queensland, 2 November 1922. Qantas named the new airliner City of Canberra. The new 747, the twelfth -400 built, with U.S. registration N6064P, it made its first flight at Seattle with Boeing’s test pilots on 3 July 1989. It was turned over to Qantas on 9 August.
Planning for the record setting flight began almost as soon as the airplane had been ordered. Although the airplane was complete and ready to enter passenger service on arrival at Sydney, certain special arrangements were made. Shell Germany refined 60,000 gallons (227,000 liters) of a special high-density jet fuel and delivered it to Heathrow. Rolls-Royce, manufacturer of the RB211-524G high-bypass turbofan engines, had agreed to specially select four engines to be installed on VH-OJA at the Boeing plant at Everett, Washington.
On the morning of the flight, City of Canberra was towed to the Hold Short position for Runway 28 Right (28R) so as not to use any of the precious fuel while taxiing from the terminal. Once there, its fuel tanks were filled to overflow. The airport fire department stood by as the excess fuel ran out of the tank vents. In the passenger cabin were two Flight Service Directors, FSD David Cohen and FSD Mal Callender, and eighteen passengers including senior executives from Qantas, Boeing, Shell as well as representatives of the Australian news media. The flight crew planned the engine start to allow for the mandatory three-minute warm-up and at approximately 0840 local, called the Tower, using the call sign Qantas 7441, and said that they were ready for takeoff.
After climbing to altitude they began the cruise portion of the flight at Flight Level 330 (33,000 feet or 10,058 meters). As fuel was burned off the airliner gradually climbed higher for more efficiency, eventually reaching a maximum altitude of 45,100 feet (13,746.5 meters) by the time they had reached the west coast of Australia.
QF7441 touched down at Sydney Airport at 2:19 p.m, local time (0419 UTC).
For a more detailed description of this flight and its planning, see John McHarg’s article, “The Delivery Flight of Qantas Boeing 747-438 VH-OJA” at:
City of Canberra, VH-OJA, remained in Qantas service until 8 March 2015. The airliner was withdrawn from service and donated to the Historical Aircraft Restoration Society Museum at Illawara Regional Airport (YWOL), New South Wales. Its distance record stood until 10 November 1995 when another Boeing airliner, a 777-200LR with Captain Suzanna Darcy-Henneman in command, set a new distance record.
The Boeing 747-400 airliner can carry between 416 and 660 passengers, depending on configuration. It is 231 feet, 10 inches (70.6 meters) long with a wingspan of 211 feet, 5 inches (64.4 meters) and overall height of 63 feet, 8 inches (19.4 meters). Empty weight is 394,100 pounds (178,800 kilograms). Maximum takeoff weight (MTOW) is 875,000 pounds (396,890 kilograms). While the prototype was powered by four Pratt and Whitney PW4056 turbofan engines, production airplanes could be ordered with PW4062, General Electric CF6 or Rolls-Royce RB211 engines, providing thrust ranging from 59,500 to 63,300 pounds. The –400 has a cruise speed of 0.85 Mach (567 miles per hour, 912 kilometers per hour) and maximum speed of 0.92 Mach (614 miles per hour, 988 kilometers hour). Maximum range at maximum payload weight is 7,260 nautical miles (13,450 kilometers).

22 July 1983: Richard Harold (“Dick”) Smith landed his Bell JetRanger III helicopter, VH-DIK, at the Bell Helicopter Hurst Heliport (0TE2), in Hurst, Texas, United States of America. He had completed the first solo around-the-world flight by helicopter.
352 days earlier, 5 August 1982, Dick Smith had departed from Hurst on an eastbound circumnavigation. He had purchased the helicopter specifically to make this flight, and named it Australian Explorer. The aircraft, as standard production Bell Model 206B-3, serial number 3653, had been built at the Bell Helicopter TEXTRON plant in Hurst. It was registered VH-DIK by the Australia Department of Aviation, 2 June 1982.
The JetRanger was equipped with a Collins LRN 70 VLF/Omega navigation system, and a Collins autopilot. A larger fuel tank was installed.
Smith’s journey was made in three major segments:
Leg 1: Hurst, Texas, U.S.A., to London, England, from 5 August to 19 August 1982
Leg 2: London, England, to Sydney, New South Wales, Australia, 13 September to 3 October 1982
Leg 3: Sydney, N.S.W., Australia, to Hurst, TX, U.S.A., 25 May to 22 July 1983
The total distance flown was reported in FLIGHT as 32,258 miles (51,914 kilometers). The total flight time was over 260 hours.
Smith’s circumnavigation had also included the first solo flight by helicopter across the Atlantic Ocean. During the journey, he set five separate Fédération Aéronautique Internationale (FAI) world records for Speed Over a Recognized Course. ¹
The Bell JetRanger is a 5-place, single-engine light civil helicopter based on the Bell Helicopter’s unsuccessful OH-4 entrant for the U.S. Army’s Light Observation Helicopter (LOH, or “loach”) contract. It is flown by a single pilot in the right front seat. Dual flight controls can be installed for a second pilot. The helicopter was certified for VFR flight, but could be modified for instrument flight.
The JetRanger is 38 feet, 9.5 inches (11.824 meters) long, overall. On standard skid landing gear the overall height is 9 feet, 4 inches (2.845 meters). The Bell 206A has an empty weight of approximately 1,700 pounds (771 kilograms), depending on installed equipment. The maximum gross weight is 3,200 pounds (1,451.5 kilograms). With an external load suspended from the cargo hook, the maximum gross weight is increased to 3,350 pounds (1,519.5 kilograms).
The two-bladed main rotor is semi-rigid and under-slung, a common feature of Bell’s main rotor design. It has a diameter of 33 feet, 4.0 inches (10.160 meters) and turns counter-clockwise (seen from above) at 394 r.p.m. (100% NR). (The advancing blade is on the helicopter’s right side.) The rotor blade has a chord of 1 foot, 1.0 inches (0.330 meter) and 10° negative twist. The airfoil is symmetrical. The cyclic and collective pitch controls are hydraulically-boosted.
The two-bladed tail rotor assembly is also semi-rigid and is positioned on the left side of the tail boom in a pusher configuration. It turns at 2,550 r.p.m., clockwise, as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.) The tail rotor diameter is 5 feet, 6.0 inches (1.676 meters).
The turboshaft engine is mounted above the roof of the fuselage, to the rear of the main transmission. Output shafts lead forward to the transmission and aft to the tail rotor 90° gear box. The transmission and rotor mast are mounted tilting slightly forward and to the left. This assists in the helicopter’s lift off to a hover, helps to offset its translating tendency, and keeps the passenger cabin in a near-level attitude during cruise flight.
A vertical fin is attached at the aft end of the tail boom. The fin is offset 4° to the right to unload the tail rotor in cruise flight. Fixed horizontal stabilizers with an inverted asymmetric airfoil are attached to the tail boom. In cruise flight, these provide a downward force that keeps the passenger cabin in a near-level attitude.
The 206A was powered by an Allison 250-C18 turboshaft engine (T63-A-700) which produced a maximum of 317 shaft horsepower at 104% N1, 53,164 r.pm. The improved Model 206B JetRanger and 206B-2 JetRanger II used a 370 horsepower 250–C20 engine, and the Model 206B-3 JetRanger III had 250-C20B, -C20J or -C20R engines installed, rated at 420 shaft horsepower at 105% N1, (53,519 r.p.m.). Many 206As were upgraded to 206Bs and they are sometimes referred to as a “206A/B.” The Allison 250-C20B has a 7-stage compressor section with 6-stage axial-flow stages, and 1 centrifugal-flow stage. The 4-stage axial-flow turbine has a 2-stage gas producer (N1) and 2-stage power turbine (N2). These were very light weight engines, ranging from just 141 to 173 pounds (64.0 to 78.5 kilograms).
The helicopter’s main transmission is limited to a maximum input of 317 shaft horsepower (100% Torque, 5-minute limit). The engine’s accessory gear unit reduces the output shaft speed to 6,016 r.p.m. N2, which is further reduced by the transmission’s planetary gears, and the tail rotor 90° gear box.
The JetRanger has a maximum speed, VNE, of 150 miles per hour (241 kilometers per hour) up to 3,000 feet (914 meters). Its best rate of climb, VY, is at 60 miles per hour (97 kilometers per hour) and best speed in autorotation (minimum rate of descent and maximum distance) is at 80 miles per hour (129 kilometers per hour), resulting in a glide ratio of about 4:1. The service ceiling is 13,500 feet (4,145 meters) with the helicopter’s gross weight above 3,000 pounds (1,361 kilograms), and 20,000 feet (6,096 meters) when below 3,000 pounds. The helicopter has a maximum range of 430 miles (692 kilometers).

11 June 1971: Sheila Scott O.B.E. (née Sheila Christine Hopkins) departed Nairobi, Kenya, on her third solo around-the-world flight. On this flight she used a new airplane, a twin-engine Piper PA-23-250 Aztec D which she named Mythre. It carried United Kingdom registration G-AYTO. Scott used a NASA navigation and locator communication system to constantly relay her position to a Nimbus weather satellite, and from there to a ground station.
Sheila Scott planned to not only fly around the world, but to fly from the Equator, over the North Pole, and back to the Equator again. She flew her Aztec from London, England, to Nairobi, Kenya, where she began the Equator–North Pole–Equator portion of the flight.
Scott took off from Nairobi on 11 June 1971 and headed northward to Khartoum, Sudan; Bengazi, Libya; Malta; arriving back at London on 21 June. From there she continued to Bodø, Norway; Andøya, Norway; Station Nord, Greenland; across the North Pole on 28 June; then southward to Barrow, Alaska; arriving at Anchorage, Alaska, on 3 July; San Francisco, California, to Honolulu, Hawaii, on 11 July. She recrossed the Equator heading south to Canton Island. On 23 July, Mythre arrived at Nadi, Viti Levu, Fiji, and then flew on to Noumea, New Caledonia. After a stop at Townsville, Queensland, Scott arrived at Darwin, Northern Teritory, Australia, 1 August. From there she continued to Singapore; Madras, India; Karachi, Pakistan; Bahrain; Athens, Greece; and finally completed her journey at London on 4 August. The trip took 55 days.
During the circumnavigation, Sheila Scott set seven Fédération Aéronautique Internationale (FAI) World Records for Speed Over a Recognized Course: Andøya, Norway, to Station Nord, Greenland, 213.61 kilometers per hour (132.73 miles per hour) ¹; Nord to Barrow, Alaska, 183.73 km/h (114.16 mph) ²; San Francisco, California, to Honolulu, Hawaii, 236.56 km/h (146.99 mph) ³; Darwin, Northern Territory, Australia, to London, England, 160.19 km/h (99.54mph). ⁴ Three of these records remain current. ⁵
Ms. Scott’s airplane was a 1971 Piper 23-250 Aztec (“Aztec D”), serial number 27-4568. The airplane was assigned the United Kingdom registration G-AYTO on 3 March 1971. The Aztec D was a six-place twin-engine light airplane based on the earlier PA-23-235 Apache, with a larger cabin and more powerful engines. It was of all-metal construction and had retractable tricycle landing gear. The Aztec D is 31 feet, 2.625 inches (9.516 meters) long with a wingspan of 37 feet, 1.750 inches (11.322 meters) and overall height of 10 feet, 3.875 inches (3.146 meters). The wing has 5° dihedral. The Aztec D has an empty weight of 3,042 pounds (1,380 kilograms) and a gross weight of 5,200 pounds (2,359 kilograms).
The Aztec D is powered by two air-cooled, fuel-injected, 541.511-cubic-inch-displacement (8.874 liter) AVCO Lycoming IO-540-C4B5 6-cylinder, horizontally-opposed, direct-drive engines. The -C4B5 has a compression ratio of 8.5:1 and a Maximum Continuous Power/Takeoff rating of 250 horsepower at 2,575 r.p.m. It weighs 374 pounds (170 kilograms). The engines drive two-bladed Hartzell constant-speed propellers with a diameter of 6 feet, 2 inches (1.880 meters).
The PA-23-250 Aztec D has a maximum structural cruising speed (VNO) of 172 knots (198 miles per hour/319 kilometers per hour) at 7,500 feet (2,286 meters) and maximum speed (VNE) of 216 knots 249 miles per hour (400 kilometers per hour). The service ceiling is 19,800 feet (6,035 meters). With standard fuel capacity of 144 gallons (545 liters) the airplane’s range is 1,055 miles (1,698 kilometers). Mythre carried an auxiliary fuel tank in the passenger cabin.
After the around-the-world flight, Scott returned Mythre to the Piper Aircraft Company at Lock Haven, Pennsylvania, for overhaul. Following Tropical Storm Agnes in June 1972, the Piper factory was flooded to a depth of 16 feet (4.9 meters) and Scott’s airplane, along with many others and much of the tooling for aircraft manufacture, was destroyed.
