12 April 1963: At Edwards Air Force Base, California, Jacqueline (“Jackie”) Cochran, Colonel, U.S. Air Force Reserve, established a Fédération Aéronautique Internationale (FAI) World Speed Record when she flew a two-place Lockheed TF-104G Starfighter, FAA registration N104L, over a 15/25 kilometer (9.32/15.53 miles) straight course at an average speed of 2,048.88 kilometers per hour (1,273.115 miles per hour).¹
Jackie Cochran wrote about flying the 15/25 kilometer straight course in her autobiography:
Picture in your mind a rectangular tunnel, 300 feet high, a quarter of a mile wide, and extending 20 miles long through the air at an altitude of 35,000 feet. I had to fly through that tunnel at top speed without touching a side. There were no walls to see but radar and ground instruments let me know my mistakes immediately. Up there at 35,000 feet the temperature would be about 45 degrees below zero. Not pleasant but perfect for what I was doing. Inside the plane you are hot because of the friction of speeding through the air like that. The cockpit was air-conditioned, but when you descend, things happen so fast the plane’s air-cooling system can’t keep up with it. I was always hot and perspiring back on the ground.
—Jackie Cochran: An Autobiography, by Jacqueline Cochran and Maryann Bucknum Brinley, Bantam Books, New York 1987, Page 314.
N104L was retained by Lockheed for use as a customer demonstrator to various foreign governments. In 1965 Lockheed sold N104L to the Dutch Air Force, where it served as D-5702 until 1980. It next went to the Turkish Air Force, remaining in service until it was retired in 1989.
4 March 1954: Lockheed test pilot Anthony W. LeVier takes the prototype XF-104 Starfighter, 53-7786, for its first flight at Edwards Air Force Base in the high desert of southern California. The airplane’s landing gear remained extended throughout the flight, which lasted about twenty minutes.
Designed by the legendary Kelly Johnson, the XF-104 was a prototype Mach 2+ interceptor and was known in the news media of the time as “the missile with a man in it.”
Tony LeVier was a friend of my mother’s family and a frequent visitor to their home in Whittier, California.
There were two Lockheed XF-104 prototypes. Initial flight testing was performed with 083-1001 (USAF serial number 53-7786). The second prototype, 083-1002 (53-7787) was the armament test aircraft. Both were single-seat, single-engine supersonic interceptor prototypes.
The XF-104 was 49 feet, 2 inches (14.986 meters) long with a wingspan of 21 feet, 11 inches (6.680 meters) and overall height of 13 feet, 6 inches (4.115 meters). The wings had 10° anhedral. The prototypes had an empty weight of 11,500 pounds (5,216 kilograms) and maximum takeoff weight of 15,700 pounds (7,121 kilograms).
The production aircraft was planned for a General Electric J79 afterburning turbojet but that engine would not be ready soon enough, so both prototypes were designed to use a Buick-built J65-B-3, a licensed version of the British Armstrong Siddeley Sapphire turbojet engine. The J65-B-3 was a single-shaft axial-flow turbojet with a 13-stage compressor section and 2-stage turbine. It produced 7,200 pounds of thrust (32.03 kilonewtons) at 8,200 r.p.m. The J65-B-3 was 9 feet, 7.0 inches (2.921 meters) long, 3 feet, 1.5 inches (0.953 meters) in diameter, and weighed 2,696 pounds (1,223 kilograms).
On 15 March 1955, XF-104 53-7786 reached a maximum speed of Mach 1.79 (1,181 miles per hour, 1,900 kilometers per hour), at 60,000 feet (18,288 meters).
XF-104 53-7786 was destroyed 11 July 1957 when the vertical fin was ripped off by uncontrollable flutter. The pilot, William C. Park, safely ejected.
Lockheed Martin has an excellent color video of the XF-104 first flight on their web site at:
29 February 1964: President Lyndon B. Johnson publicly revealed the existence of the Top Secret Lockheed YF-12A, a Mach 3+ interceptor designed and built by Clarence L. “Kelly” Johnson’s “Skunk Works.” President Johnson referred to the interceptor as the “A-11.”
Intended as a replacement for Convair’s F-106 Delta Dart, three pre-production YF-12As were built for testing. On 1 May 1965, a YF-12A set a speed record of 2,070.103 miles per hour (3,331.507 kilometers per hour) and reached an altitude of 80,259 ft (24,463 meters).
The reason for President Johnson’s announcement of the existence of the YF-12A prototypes was to conceal the existence of the Central Intelligence Agency’s fleet of Lockheed A-12 Oxcart reconnaissance aircraft based at Groom Lake, Nevada. Any sightings of these aircraft could be attributed to test flights of the YF-12As based at Edwards Air Force Base, 160 miles (258 kilometers) to the southwest.
The YF-12A interceptor is very similar to its A-12 Oxcart and SR-71A Blackbird stablemates. It a large twin-engine delta wing aircraft, flown by a pilot and weapons system operator. Because of the altitudes that the F-12 operates, the crew wears S901F full-pressure suits produced by the David Clark Company. The A-12 is 101.6 feet (30.97 meters) long with a wingspan of 55.62 feet (16.953 meters) and overall height of 18.45 feet (5.624 meters). It has a zero fuel weight of 54,600 pounds (24,766 kilograms) and a maximum ramp weight of 124,600 pounds (56,518 kilograms). ¹
The YF-12A is powered by two Pratt & Whitney J58 (JT11D-20A) engines. These are single rotor bleed-bypass turbojets with a 9-stage compressor section and 2-stage turbine. They have a static thrust rating of 31,500 pounds (140.118 kilonewtons), each, at Sea Level with afterburning. The J58s use a unique JP-7 fuel.
The YF-12A has a maximum speed of Mach 3.35 (2,232 miles per hour/3,342 kilometers per hour) at 80,000 feet (24,384 meters). The A-12 has a normal operating cruise speed of Mach 3.1. Its maximum operating altitude is 85,000 feet (25,908 meters) and it has a range of 3,000 miles (4,828 kilometers). Unlike most fighters, the A-12 has a maximum load factor of 2.5 gs. Its maximum bank angle when above Mach 2.5 is 30°.
The United States Air Force ordered 93 production F-12B aircraft, which would have been armed with three Hughes AIM-47A Falcon air-to-air missiles in enclosed bays in the bottom of the fuselage. However, Secretary of Defense Robert S. McNamara refused to release the funds for the purchase for three consecutive years and eventually the project was cancelled.
The first YF-12A, 60-6934, seen in the top photograph, was extensively damaged by a brake system fire on landing at Edwards AFB, 14 August 1966. It was salvaged and rebuilt as SR-71C 61-7981. The third YF-12A, shown in the photograph below, was lost due to an inflight fire 24 June 1971. The crew safely ejected.
The only existing YF-12A, 60-6935, is in the collection of the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Ohio.
¹ The Lockheed SR-71A has a length of 107.4 feet (32.74 meters). Wingspan and height are the same. Its zero fuel weight varied from 56,500–60,000+ pounds (25,628–27,216+ kilograms) and the gross weight had a range of approximately 135,000–140,000+ pounds (61,235–63,503+ kilograms).
21 January–8 February 1971: A Lockheed P-3C Orion antisubmarine warfare patrol bomber, Bu. No. 156512, under the command of Commander Donald H. Lilienthal, United States Navy, took off from Naval Air Station Atsugi, Japan, at 23:30 UTC, Thursday, 21 January (8:30 a.m., 22 January, Japan Time), and flew 11,036.47 kilometers (6,857.75 statute miles), non-stop, to NATC Patuxent River, Maryland. The airplane landed at 8:51 a.m., Eastern Standard Time (13:51 UTC), Friday, 22 January. The duration of the flight was 15 hours, 21 minutes.
This was a new Fédération Aéronautique Internationale (FAI) world distance record for turboprop airplanes.¹ The Orion’s course deviated around foreign airspace so the actual distance flown was 7,010 miles (11,218.5 kilometers).
For the long distance flight the Orion carried a flight crew of seven: Commander Donald H. Lilienthal, Aircraft Commander; Captain R.H. Ross, Pilot; Lieutenant Commander F. Howard Stoodley, Pilot; Lieutenant R.T. Myers, Navigator; Commander J.E. Koehr, Meteorologist; Chief Aviation Machinist’s Mate K.D. Frantz, Flight Engineer; and Chief Aviation Electrician’s Mate H.A. Statti, Flight Engineer.
On Wednesday, 27 January 1971, the same airplane set both FAI and National Aeronautic Association records for Speed Over a Straight Course of 15/25 Kilometers of 806.10 kilometers per hour (500.89 miles per hour) at NAS Patuxent River.²
The U.S. National Record still stands:
On February 4, at Edwards Air Force Base in the high desert of Southern California, Commander Lilienthal flew 156512 to a World Record for Altitude in Horizontal Flight of 13,721.5 meters (45,018.1 feet).³
On 8 February 1971, while till at Edwards AFB, Commander Lilienthal and 156512 set five more world records for heavy turboprop airplanes. The P-3C climbed to a height of 3,000 meters (9,843 feet) in 2 minutes, 52 seconds ⁴ ; to 6,000 meters (19,685 feet) in 5 minutes, 46 seconds ⁵ ; to 9,000 meters (29, 528 feet) in 10 minutes, 26 seconds ⁶ ; and 12,000 meters (39,370 feet) in 19 minutes, 42 seconds.⁷ The Orion continued climbing until it reached a world record altitude of 14,086.1 meters (46,214.2 feet). ⁸
For his record-setting flights, Commander Lilienthal was awarded the Distinguished Flying Cross.
The record-setting airplane was a Lockheed Model 285A P-3C-110-LO Orion, Bu. No. 156512, LAC serial number 5506, built by the Lockheed-California Company at Burbank, California. The Orion was completed 14 August 1969. It was assigned to the Naval Air Test Center at NAS Patuxent River, Maryland. The Orion was a standard production P-3C with no engine or fuel system modifications.
The Lockheed P-3 Orion was developed from the Model 188 Electra—a four-engine turboprop airliner which first flew in 1957—primarily as a long-range anti-submarine warfare and maritime surveillance aircraft. The P-3 has been adapted to many other missions. The P-3C variant in U.S. Navy service is usually operated by a crew of 11.
The bomber is 116 feet, 10 inches (35.611 meters) long with a wingspan of 99 feet, 8 inches (30.378 meters) and overall height of 34 feet, 3 inches (10.439 meters). It has a zero-fuel weight of 77,200 pounds (35,017 kilograms) and a normal maximum takeoff weight of 135,000 pounds (61,235 kilograms) (Overload Takeoff: 139,780 pounds/63,403 kilograms).
The P-3C is powered by four Allison T56-A-14 turboprop engines which produce 4,591 shaft horsepower at 13,820 r.p.m., each. They drive four-bladed Hamilton-Standard 54H60-77 constant-speed propellers with a diameter of 13 feet, 5¾ inches (4.109 meters) at 1,020 r.p.m. The T56-A-14 is a single-shaft axial-flow turboprop engine, with a 14-stage compressor section, six combustors, and a 4-stage turbine. The engine is 12 feet, 2.3 inches (3.716 meters) long, 4 feet, 1.0 inches (1.245 meters) in diameter and weighs 1,885 pounds (855 kilograms).
The P-3C can remain airborne for 16 hours.
There is a wide variety of sensors board the P-3. Sonobuoys can be dropped from the belly. A Magnetic Anomaly Detector, the “MAD boom” is mounted at the tail of the aircraft.
The Orion caries no defensive weapons. It can carry bombs, depth charges, torpedoes, mines, air-to-surface and anti-ship missiles, and nuclear weapons.
More than 750 P-3 Orions and its variants were built by Lockheed and licensee Kawasaki Heavy Industries between 1961 and 1996. In addition to the U.S. Navy and various Federal government agencies, the Lockheed P-3 Orion remains in service worldwide with more than twenty countries.
Lockheed P-3C-110-LO Orion Bu. No. 156512 served as a test aircraft at Patuxent River until 15 July 1974. It was then assigned to VP-31 where it remained for over nine years, carrying the squadron identification marking RP and the numeral 9. It later served with VP-9, VP-46, VP-65, VP-16 and finally, VP-45. 156512 was placed in long-term storage at Davis-Monthan Air Force Base, Tucson, Arizona, in 1995, and was scrapped in 2004.
Donald Herman Lilienthal was born 6 February 1931 at Pope, Minnesota. He was the fourth child of Frederick R. Lilienthal, a steam railway worker, and Bertha Camille Metlie Lilienthal. He attended Glenwood High School, Glenwood, Minnesota, graduating in 1949. He then studied mathematics at the University of Minnesota, before accepting an appointment as a midshipman at the United States Naval Academy at Annapolis, Maryland, in 1951.
Midshipman Lilienthal graduated from Annapolis and was commissioned an ensign, United States Navy, 3 June 1955. He was then trained as a pilot. Later, he graduated from the United States Naval Test Pilot School at NAS Patuxent River, Maryland.
In June 1958, Lieutenant (j.g.) Lilienthal married Miss Jeanne L. Murphy, in Duval County, Florida. They had three children, Karen, John and Donald, Jr. They divorced in March 1975.
Lieutenant (j.g.) Lilienthal was promoted to the rank of lieutenant 1 July 1959, and to lieutenant commander, 1 July 1964. He advanced to commander on 1 July 1969.
Commander Lilenthal retired from the United States Navy in December 1975 after 20 years of service as an antisubmarine warfare pilot and test pilot. He later worked as a consultant to the aviation industry.
Commander Lilienthal married Mrs. Jimena Rosa Goich Recavrren, a widow, in Arlington, Virginia, 17 September 1982. They divorced 3 December 1993 in Fairfax, Virginia.
Commander Donald Herman Lilienthal, United States Navy (Retired) passed away at Loudon, Virginia, 21 August 2014 at the age of 83 years. He is buried at Arlington National Cemetery, Arlington, Virginia.
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.
