15 August 1962: American Airlines’ Captain Eugene M. (“Gene”) Kruse set a National Aeronautic Association Class C-1 record for Speed Over a Commercial Air Route, East to West Transcontinental, when he flew a Boeing 720B Astrojet from New York to Los Angeles, 2,474 miles (3,981.5 kilometers), in 4 hours, 19 minutes, 15 seconds, at an average speed of 572.57 miles per hour (921.46 kilometers per hour). 56 years later, this record still stands.
The National Aeronautic Association has placed Captain Kruse’ record on its “Most Wanted” list: long-standing flight records that it would like to see challenged. Rules require that a new record exceed the old by at least a 1% margin. The performance needed to establish a new record would be 578.30 miles per hour (930.68 kilometers per hour).
The Boeing 720 was a variant of the Model 707, intended for short to medium range flights. It had 100 inches (2.54 meters) removed from the fuselage length and improvements to the wing, decreasing aerodynamic drag.
The Boeing 720 was operated by a flight crew of four and could carry up to 149 passengers. It was 136 feet, 2 inches (41.25 meters) long with a wingspan of 130 feet, 10 inches (39.90 meters) and overall height of 41 feet, 7 inches (12.65 meters). The airplane had an empty weight of 103,145 pounds (46,785 kilograms) and Maximum Takeoff Weight of 220,000 pounds (100,800 kilograms).
The Boeing 720 was powered by four Pratt & Whitney Turbo Wasp JT3C-7 turbojet engines, a civil variant of the military J57 series. The 720B was equipped with the more efficient P&W JT3D-1 turbofan engines. The JT3C-7 was a “two-spool” axial-flow engine with a 16-stage compressor (9 low- and 7 high-pressure stages), 8 combustion tubes, and a 3-stage turbine (1 high- and 2 low-pressure stages). It was rated at 12,030 pounds of thrust (53.512 kilonewtons) for takeoff. The JT3D-1 was a dual axial-flow turbofan engine, with a 2-stage fan section 13-stage compressor (6 low- and 7 high pressure stages), 8 combustion chambers and a 4-stage turbine (1 high- and 3 low-pressure stages). This engine was rated at 14,500 pounds of static thrust (64.499 kilonewtons) at Sea Level, and 17,000 pounds (75.620 kilonewtons), with water injection, for takeoff (2½ minute limit). Almost half of the engine’s thrust was produced by the fans. Maximum engine speed was 6,800 r.p.m. (N1) and 10,200 r.p.m. (N2). It was 11 feet, 4.64 inches (3.471 meters) long, 4 feet, 5.00 inches (1.346 meters) wide and 4 feet, 10.00 inches (1.422 meters) high. It weighed 4,165 pounds (1,889 kilograms). The JT3C could be converted to the JT3D configuration during overhaul.
The maximum cruise speed was 611 miles per hour (983 kilometers per hour) and maximum speed was 620 miles per hour (1,009 kilometers per hour). Range at at maximum payload was 4,370 miles (7,033 kilometers).
Boeing built 154 720 and 720B airliners from 1959 to 1967.
The last flight of a Boeing 720 was on 9 May 2012, when a 720B aircraft used by Pratt and Whitney Canada as a test aircraft was placed in the National Air Force Museum of Canada at Trenton, Ontario.
23 July 1970: At Long Beach, California, the first McDonnell Douglas DC-10 airliner was rolled out. A DC-10-10, serial number 46500 with FAA registration N10DC, this aircraft was used for flight testing and Federal Aviation Administration certification. It made 989 test flights, accumulating 1,551 flight hours. It was put into commercial service with American Airlines 12 August 1972, re-registered as N101AA.
The DC-10 was a wide-body commercial airliner designed for medium to long range flights. It was flown by a crew of three and depending on the cabin arrangement, carried between 202 and 390 passengers. The DC-10-10 was 170 feet, 6 inches (51.968 meters) long with a wingspan of 155 feet, 4 inches (47.346 meters) and overall height of 58 feet, 1 inch (17.704 meters). The airliner had an empty weight of 240,171 pounds (108,940 kilograms) and maximum takeoff weight of 430,000 pounds (195,045 kilograms). It was powered by three General Electric CF6-6D turbofan engines, producing 40,000 pounds of thrust, each. These gave the DC-10 a maximum cruise speed of Mach 0.88 (610 miles per hour, 982 kilometers per hour). Its range is 3,800 miles (6,116 kilometers) and the service ceiling is 42,000 feet (12,802 meters).
In production from 1970 to 1988, a total of 386 DC-10s were built in passenger and freighter versions. 122 were the DC-10-10 variant. Another 60 KC-10A Extender air refueling tankers were built for the U.S. Air Force and 2 KDC-10 tankers for the Royal Netherlands Air Force.
The first McDonnell Douglas DC-10 was in service with American Airlines from 12 August 1972 to 15 November 1994 when it was withdrawn from service and placed in storage at Tulsa, Oklahoma. The 24-year-old airliner had accumulated 63,325 flight hours.
After three years in storage, the first DC-10 returned to service flying for Federal Express. In 1998 it was modernized as an MD-10 and re-registered again, this time as N530FE. It was finally retired from service and scrapped at Goodyear, Arizona in 2002.
25 January 1959: “The Jet Age” opened when American Airlines began the first scheduled transcontinental passenger service with its new Boeing 707-123 Astrojet. Captain Charles A. Macatee III flew Flagship California, N7503A, from Los Angeles International Airport on the coast of southern California, to New York International Airport ¹ in New York City, in 4 hours and 3 minutes.
Other members of the inaugural flight crew were Captain Lou Szabo, Flight Engineer Bill Duncan, Flight Engineer Norman Rice, Stewardess Claire Bullock, Stewardess Edna Garrett, Stewardess Argie Hoskins and Stewardess Marilyn Rutkowski. Cyrus Rowlett Smith, president of the airline, was also aboard as a passenger.
The flight departed LAX via Runway 25 at 9:05 a.m., Pacific Standard Time. Ceremonies at the airport, with as many as 25,000 spectators, delayed the flight by twenty minutes, but a 150 knot (278 kilometers per hour) tailwind allowed the flight to make up for the lost time and they arrived at Idlewild Airport on schedule.
Flagship California returned to Los Angeles the same day. Flown by Captain Hamilton C. Smith, the 707 departed Idlewild at 6:26 p.m., Eastern Standard Time, arriving at LAX 6 hours, 33 minutes later.
This flight was so significant that rival airlines, such as B.O.A.C. and Pan Am took out full-page newspaper advertisements congratulating American Airlines on its inaugural jet flight.
Ticket prices for one-way, First Class, were $198.88, and $124.40 for coach. Eastbound passengers included actress Jane Wyman and World War II fighter pilot, Brigadier General Robert Lee Scott, Jr., author of God is My Co-Pilot. Poet Carl Sandburg flew on the westbound return flight.
Prior to the first passenger flight, Captain Macatee and Captain Smith had flown the Boeing 707 for 200 hours. In an interview thirty years later, Macatee remarked, “But those four hours three minutes were the big ones for me. They always will be.”
The Boeing 707 was developed from the earlier Model 367–80, the “Dash Eighty.” It is a four-engine jet transport with swept wings and tail surfaces. The leading edge of the wings are swept at a 35° angle. The airliner had a flight crew of four: pilot, co-pilot, navigator and flight engineer. The airliner could carry a maximum of 189 passengers.
The 707-123 was 145 feet, 1 inch (44.221 meters) long with a wing span of 130 feet, 10 inches (39.878 meters). The top of the vertical fin stood 42 feet, 5 inches (12.929 meters) high. The 707 pre-dated the ”wide-body” airliners, having a fuselage width of 12 feet, 4 inches (3.759 meters). The airliner’s empty weight is 122,533 pounds (55,580 kilograms). Maximum take off weight is 257,000 pounds (116,573 kilograms).
The first versions were powered by four Pratt & Whitney Turbo Wasp JT3C-6 turbojet engines, producing 11,200 pounds of thrust (49,820 kilonewtons), and 13,500 pounds (60.051 kilonewtons) with water injection. This engine was a civil variant of the military J57 series. It was a two-spool axial-flow turbojet engine with a 16-stage compressor and 2 stage turbine. The JT3C-6 was 11 feet, 6.6 inches (3.520 meters) long, 3 feet, 2.9 inches (0.988 meters) in diameter, and weighed 4,235 pounds (1,921 kilograms).
At MTOW, the 707 required 11,000 feet (3,353 meters) of runway to take off.
The 707-121 had a maximum speed of 540 knots (1,000 kilometers per hour). It’s range was 2,800 nautical miles (5,186 kilometers).
The Boeing 707 was in production from 1958 to 1979. 1,010 were built. Production of 707 airframes continued at Renton until the final one was completed in April 1991.
In 1961, N7503A was upgraded to the 707-123B standard. This included a change from the turbojet engines to quieter, more powerful and efficient Pratt & Whitney JT3D-1. The JT3D-1 was a dual spool axial-flow turbofan engine, with a 2-stage fan section, 13-stage compressor (6 low- and 7 high pressure stages), 8 combustion chambers and a 4-stage turbine (1 high- and 3 low-pressure stages). This engine was rated at 14,500 pounds of static thrust (64.499 kilonewtons) at Sea Level, and 17,000 pounds (75.620 kilonewtons), with water injection, for takeoff (2½ minute limit). Almost half of the engine’s thrust was produced by the fans. Maximum engine speed was 6,800 r.p.m. (N1) and 10,200 r.p.m. (N2). It was 11 feet, 4.64 inches (3.471 meters) long, 4 feet, 5.00 inches (1.346 meters) wide and 4 feet, 10.00 inches (1.422 meters) high. It weighed 4,165 pounds (1,889 kilograms). The JT3C could be converted to the JT3D configuration during overhaul.
The 707-123B wings were modified to incorporate changes introduced with the Boeing 720, and a longer tailplane installed.
N7503A was substantially damaged at Mineral Wells, Texas, 9 May 1965. It had flown through a violent thunderstorm and suffered hail damage. The crew made a precautionary landing, however the windshield had been crazed so badly by the impact of hail that it was opaque. The 707 made a hard landing and its gear collapsed. There were no injuries among the 89 passengers and 7 crewmembers. It was repaired and returned to service.
After 28 years, American Airlines’ inaugural Astro Jet was scrapped.
¹ New York International Airport, located in Queens, a borough of New York City, was commonly called Idlewild Airport. In 1963, the name was changed to John F. Kennedy International Airport (JFK).
14–15 January 1935: James Harold Doolittle set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Recognised Course of 329.98 kilometers per hour (205.04 miles per hour).¹
Doolittle took off from Union Air Terminal, Burbank, California, at 5:27 p.m., Pacific Standard Time, 14 January (8:27 p.m., Eastern Standard Time). Also on board were Mrs. Doolittle and Robert Adamson (1871–1935), an executive with the Shell Oil Company.
The airplane was an Airplane Development Corporation V-1A Special, NC13770, owned by American Airlines and leased to Shell.
Doolittle crossed overhead Floyd Bennett Field at 8:26 a.m., Eastern Standard Time, 15 January. He then landed at Newark Airport, New Jersey, at 8:34½ a.m. The flight from Burbank to Brooklyn had a duration of 11 hours, 59 minutes, and broke a record set two months earlier by Eddie Rickenbacker.
The Airplane Development Corporation Model V-1A (commonly known as the “Vultee V-1A”) was a large, all-metal, single-engine, low-wing monoplane with retractable landing gear. The V-1A was designed as a high-speed airliner and was of full monocoque construction. It could be flown by one or two pilots and carry up to eight passengers.
The V-1A was designed by Gerard Freebairn Vultee and Richard Palmer,² based on an earlier design by Vultee and Vance Breese, who were working for the Airplane Development Corporation, which they had founded in 1932, but which had been acquired by the Cord Corporation. The prototype made its first flight 19 February 1933 with test pilot Marshall Headle at the controls.
NC13770, serial number 24073, was the eighth V-1A built, and was one of the original ten ordered by American Airlines. The V-1A was 37 feet, 0 inches (11.278 meters) long with a wingspan of 50 feet, 0 inches (15.240 meters) and height of 10 feet, 2 inches (3.099 meters). The wings had root chord of 11 feet, 3 inches (3.429 meters) and tip chord of 5 feet, 0 inches (1.524 meters). Total wing area was 384.0 square feet (35.675 square meters). There was 3° dihedral. The V-1A had an empty weight of 5,212 pounds (2,364 kilograms) and gross weight of 8,500 pounds (3,856 kilograms).
The Vultee V-1A was powered by an air-cooled, supercharged, 1,823.129 cubic-inch displacement (29.785 liter) Wright Aeronautical Division Cyclone 9 R-1820-F2 (R-1820-20 or R-1820-102), a nine-cylinder radial engine with a compression ratio of 6.4:1. This was a direct-drive engine with a Normal Power rating of 691 horsepower at 1,950 r.p.m., at Sea Level. It required 87-octane gasoline. The engine turned a three-blade propeller with a diameter of 10 feet, 0 inches (3.048 meters). The R-1820-F2 was 3 feet, 7-3/8 inches (1.102 meters) long, 4 feet, 5-3/4 inches (1.365 meters) in diameter, and weighed 937 pounds (425 kilograms).
The V-1A had a cruise speed of 215 miles per hour (346 kilometers per hour) and maximum speed of 235 miles per hour (378 kilometers per hour). The airplane’s service ceiling was 23,000 feet (7,010 meters). In standard configuration, it had a range of 1,000 miles (1,609 kilometers).
NC13770 was later sold to Harry Richman of Miami Beach, Florida, who christened the airplane Lady Peace. During the Spanish Civil War, the airplane was captured by the Nationalists. It was used as a transport for the Aviación Nacional Grupo 43, identified as 43-14, and named Capitán Haya. Its U.S. registration was cancelled 8 October 1937. It is believed that the airplane was scrapped in the early 1950s.

² Richard Palmer was the designer of Howard Hughes’ record setting H-1.
17 December 1935: Douglas Aircraft Company vice president and chief test pilot Carl A. Cover made the first flight of the Douglas DST, NX14988, at Clover Field, Santa Monica, California. Also aboard were engineers Fred Stineman and Frank Coleman.
Designed over a two year period by chief engineer Arthur Emmons Raymond and built for American Airlines, the DST, or Douglas Sleeper Transport, was the original variant of the DC-3 commercial airliner. It had 14 sleeping berths for passengers on overnight transcontinental journeys, and could fly across the United States with three refueling stops. There were no prototypes built. NX14988 was a production airplane and went to American Airlines where it flew more than 17,000 hours.
At the beginning of World War II, NC14988 was placed in military service, designated C-49E Skytrooper with the serial number 42-43619. On 15 October 1942, it crashed 2 miles (3.2 kilometers) from its destination at Chicago, Illinois, killing the 2-man crew and all 7 passengers. The airplane was damaged beyond repair.
The DST and the DC-3 were an improved version of the Douglas DC-2 commercial transport. It was an all-metal, twin-engine, low-wing monoplane with retractable landing gear. The airplane was operated by a pilot and co-pilot.
The Douglas DC-3 was 64 feet, 5½ inches (19.647 meters) long with a wingspan of 95 feet, 0 inches (28.956 meters). It was 17 feet, 0 inches (5.182 meters) high in three-point position. The wing center section is straight, but outboard of the engine nacelles there is 5º dihedral. The wings’ leading edges are swept aft 15.5°. The trailing edges have no sweep. The airplane weighed 16,384 pounds (7,432 kilograms) empty and had a gross weight of 24,400 pounds (11,068 kilograms).
DSTs and initial production DC-3s were powered by two air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.875 liter) Wright Aeronautical Division Cyclone 9 GR-1820G2 9-cylinder radial engines, rated at 700 horsepower at 2,100 r.p.m., and 800 horsepower at 2,100 r.p.m for takeoff. They drove 11 feet, 6 inch (3.505 meters) diameter, three-bladed Hamilton-Standard Hydromatic constant-speed propellers through a 16:11 gear reduction.
The engines were soon changed to more powerful 1,829.389-cubic-inch-displacement (29.978 liter) air-cooled, supercharged Pratt & Whitney Twin Wasp SC3-G 14-cylinder radials, with a normal power rating of 950 horsepower at 2,550 r.p.m., and takeoff power rating of 1,050 horsepower at 2,700 r.p.m. The SC3-G had a 16:9 propeller gear reduction ratio. It was 5 feet, 1.50 inches (1.562 meters) long, 4 feet, 0.19 inches (1.224 meters) in diameter, and weighed 1,457 pounds (661 kilograms).
The DC-3’s cruise speed was 180 knots (207 miles per hour/333 kilometers per hour), and its aximum speed was 200 knots (230 miles per hour’370 kilometers per hour) at 8,500 feet (2,591 meters). The service ceiling was 23,200 feet (7,071 meters).
The DC-3 was in production for 11 years. Douglas Aircraft Company built 10,655 DC-3s and military C-47s. There were another 5,000 license-built copies. Over 400 DC-3s are still in commercial service. The oldest surviving example is the sixth DST built, originally registered NC16005.
