11 September 1953: At Naval Ordnance Test Station China Lake, the experimental Philco/General Electric XAAM-N-7 “Sidewinder” heat-seeking air-to-air missile scored its first “hit” when it passed within 2 feet (0.6 meters) of a radio-controlled Grumman F6F-5K Hellcat. The missile was fired from a Douglas AD-4 Skyraider flown by Lieutenant Commander Albert Samuel Yesensky, United States Navy, the Officer-in-Charge (OIC) of Guided Missile Unit SIXTY-ONE (GMU-61).
The Sidewinder was later redesignated AIM-9. It entered service in 1956 as the AIM-9B and has been a primary fighter weapon for 60 years.
The AIM-9 Sidewinder is a Mach 2.5+ missile, equipped with an infrared seeker to track the heat signature of the target aircraft. (The Hellcat drones used in the early test had flares mounted on the wingtips to give the experimental missile a target).
The current production version, AIM-9X Block II, is produced by Raytheon Missile Systems, Tucson, Arizona. It is 9 feet, 11 inches long (3.023 meters), 5 inches in diameter (12.70 centimeters), and weighs 188 pounds (85 kilograms). The warhead weighs 20.8 pounds (9.4 kilograms). The missile’s range and speed are classified. At current production levels, the average cost of each AIM-9X is $420,944 (FY 2015 cost). Block III development was cancelled for FY 2106.
Future Astronaut Wally Schirra flew many of the early test flights at NOTS China Lake. On one occasion, a Sidewinder came back at him, and only by skill and luck was he able to evade it.
NOTC China Lake is now designated as Naval Air Weapons Station (NAWS) China Lake. It is located approximately 55 miles (88 kilometers) north-northeast of Edwards Air Force Base in the high desert of Southern California.
29 August 1970: The McDonnell Douglas prototype widebody airliner, DC-10-10, N10DC, made its first flight from Long Beach Airport to Edwards Air Force Base, California, where it underwent flight testing and F.A.A. certification. The aircraft commander was the company Project Pilot, Clifford L. Stout, with Deputy Chief Engineering Pilot Harris C. Van Valkenburg as co-pilot. John D. Chamberlain was the flight engineer and the flight test engineer was Shojun Yukawa.
During the first flight the DC-10 reached 300 knots (345.2 miles per hour, 555.6 kilometers per hour) and 30,000 feet (9,144 meters). The primary purpose of this flight was to check the airliner’s basic flight characteristics, aircraft systems and the installed test equipment. The flight lasted 3 hours, 36 minutes.
During the test program, N10DC 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 (177.93 kilonewtons), 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 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.
22 August 1963: On his twenty-fifth and last flight with the X-15 program, NASA Chief Research Test Pilot Joseph Albert Walker would attempt a flight to Maximum Altitude. Engineers had predicted that the X-15 was capable of reaching 400,000 feet (121,920 meters) but simulations had shown that a safe reentry from that altitude was risky. For this flight, Flight 91, the flight plan called for 360,000 feet (109,728 meters) to give Walker a safety margin. Experience had shown that slight variations in engine thrust and climb angle could cause large overshoots in peak altitude, so this was not considered an excessive safety margin.
For this flight, Joe Walker flew the Number 3 X-15, 56-6672. It was the only one of the three North American Aviation X-15s equipped with the Honeywell MH-96 flight control system, which had been developed to improve control of the rocketplane outside Earth’s atmosphere. This flight was the twenty-second for Number 3.
Walker and the X-15 were airdropped from the Boeing NB-52A Stratofortress 52-003, The High and Mighty One, at 45,000 feet (13,716 meters) above Smith Ranch Dry Lake, Nevada, about half-way between the city of Reno and the NASA High Range Tracking Station at Ely. Launch time was 10:05:57.0 a.m., PDT. Walker ignited the Reaction Motors XLR99-RM-1 rocket engine. This engine was rated at 57,000 pounds of thrust. Experience had shown that different engines varied from flight to flight and that atmospheric conditions were a factor. Thrust beyond 60,000 pounds was often seen, but this could not be predicted in advance. The flight plan called for the duration of burn to be 84.5 seconds on this flight. The X-15 climbed at a 45° angle.
As Walker was about to shut down the engine according to plan, it ran out of fuel. The total burn time was 85.8 seconds, just slightly longer than planned.
“At burnout, Joe was passing 176,000 feet [53,645 meters] and traveling at 5,600 feet per second [1,707 meters per second]. He then began the long coast to peak altitude. It would take almost 2 minutes to reach peak altitude after burn out. Two minutes does not seem like a lot of time, but try timing it. Just sit back in your easy chair and count off the seconds. It is almost impossible to believe that you can continue to coast up in altitude for that length of time after the engine burns out. It gives you some feel for how much energy is involved at those speeds. For comparison, when you throw a ball up in the air as hard as you can, it only coasts upward a maximum of 4 or 5 seconds. The X-15 coasted up for 120 seconds.
“The airplane would coast up another 178,000 feet [54,254 meters] during that time to peak out at 354,200 feet. . . .” [107,960 meters]
—At The Edge of Space: The X-15 Flight Program, by Milton O. Thompson, Smithsonian Institution Press, Washington, 1992, Chapter 5 at Page 125.
Joe Walker and the X-15 reached the peak of their ballistic trajectory at 354,200 feet (67.083 miles, 107,960 meters). Walker pitched the nose down to be in the proper attitude for atmospheric reentry. The X-15 decelerated as it hit the atmosphere and Walker experienced as much as 7 Gs. The rocketplane’s aerodynamic control surfaces again became operational as it descended through 95,000 feet (28,956 meters) and Walker leveled at 70,000 feet (21,336 meters). He then glided to a landing on Rogers Dry Lake at Edwards Air Force Base, California, after 11 minutes, 8.6 seconds of flight.
Flight 91 was the highest flight achieved by any of the X-15s. It was Joe Walker’s second flight into space. His record would stand for the next 41 years.
22 August 1953: After one successful glide flight with Bell Aircraft Corporation test pilot Skip Ziegler, the X-1D rocketplane, serial number 48-1386, was scheduled for its first powered flight with the Air Force project officer, Lieutenant Colonel Frank Kendall (“Pete”) Everest.
The Bell X-1D was one of four second-generation X-1 rocketplanes, each designed and built to investigate a different area of supersonic flight. The X-1D was instrumented for aerodynamic heating research.
After being carried to altitude by the Boeing EB-50A Superfortress mothership, Pete Everest saw that the rocketplane’s nitrogen pressure was dropping. (Pressurized nitrogen was used to push the ethyl alcohol/liquid oxygen propellant to the Reaction Motors XLR11-RM-5 engine.) With insufficient pressure, the X-1D’s flight had to be cancelled. Everest tried to jettison the fuel so that a landing could be made safely. There was an internal explosion.
Fearing that a larger explosion or fire would jeopardize the bomber and its crew, Everest abandoned the X-1D, climbing up into the bomber. The X-1 was then dropped. It crashed onto the desert floor and exploded.
At first it was assumed that vapors from a fuel leak had exploded from contact with an electrical source inside the rocketplane. There had been three similar explosions which resulted in the destruction of the X-1A, X-1-3 and the number two Bell X-2. That explosion, which occurred while the X-2 was on a captive test flight near the Bell Aircraft Corporation Factory, Buffalo, New York, 12 May 1953, killed test pilot Skip Ziegler and flight test engineer Frank Wolko aboard the B-29 mothership.
Investigators discovered that leather gaskets which were used in the rocketplanes’ fuel systems had been treated with tricresyl phospate (TCP). When this was exposed to liquid oxygen, an explosion could result. The leather gaskets were removed from the other rocketplanes and the explosions stopped.
Colonel Everest’s close call was dramatized in the 1956 Toluca Productions motion picture, “Toward The Unknown,” which starred Academy Award-winning actor William Holden as “Major Lincoln Bond,” a fighter pilot, test pilot and former prisoner of war, all of which could describe Pete Everest.
Frank Kendall (“Pete”) Everest, Jr., was born 10 August 1920, at Fairmont, Marion County, West Virginia. He was the first of two children of Frank Kendall Everest, an electrician, and Phyllis Gail Walker Everest. He attended Fairmont Senior High School, Fairmont, West Virginia, graduating in 1938, and then Fairmont State Teachers College where he was a member of the Tau Beta Iota (ΤΒΙ) fraternity. Everest also studied engineering at the University of West Virginia in Morgantown.
Pete Everest enlisted as an aviation cadet in the United States Army Air Corps at Fort Hayes, Columbus, Ohio, 7 November 1941, shortly before the United States entered World War II. His enlistment records indicate that he was 5 feet, 7 inches (1.70 meters) tall and weighed 132 pounds (60 kilograms). Everest graduated from pilot training and was commissioned as a second lieutenant, Air Reserve, 3 July 1942.
Lieutenant Everest married Miss Avis June Mason in Marion County, West Virginia, 8 July 1942. They would have three children, Frank, Vicky and Cindy.
Lieutenant Everest was appointed first lieutenant, Army of the United States (A.U.S.), 11 November 1942. He was assigned as a Curtiss-Wright P-40 Warhawk fighter pilot. Everest flew 94 combat missions with the 314th Fighter Squadron, 324th Fighter Group, in North Africa, Sicily and Italy. He was credited with shooting down two Luftwaffe Junkers Ju-52 transports, 18 April 1943, and damaging a third. Everest was promoted to the rank of captain, A.U.S., 17 August 1943.
In 1944, Captain Everest was returned to the United States to serve as a flight instructor. He requested a return to combat and was then sent to the China-Burma-India theater of operations, commanding the 17th Provisional Fighter Squadron at Chenkiang (Zhenjiang), China, where he flew 67 missions in the Northh American P-51 Mustang, and shot down four Japanese airplanes. He was himself shot down by ground fire in May 1945. Everest was captured by the Japanese and suffered torture and inhumane conditions before being freed at the end of the war. He was promoted to the rank of major, A.U.S., 1 July 1945. He was returned to the control of the United States military 3 October 1945.
After the war, Major Everest was assigned as a test pilot at Wright-Patterson Air Force Base, Ohio, before going west to the Air Force Flight Test Center at Edwards Air Force Base, California.
Everest’s permanent rank was advanced from second lieutenant, Air Reserve, to first lieutenant, Air Corps, 19 June 1947, with date of rank retroactive to 3 July 1945.
At Edwards, Pete Everest was involved in nearly every flight test program, flying the F-88, F-92, F-100 (he flew the YF-100A prototype to an FAI world speed record, 29 October 1953¹), F-101, F-102, F-104 and F-105 fighters, the XB-51, YB-52, B-57 and B-66 bombers. He also flew the pure research aircraft, the “X planes:” the X-1, X-1B, X-2, X-3, X-4 and X-5. Pete Everest flew the Bell X-1B to Mach 2.3, and he set an unofficial world speed record with the Bell X-2 at Mach 2.87 (1,957 miles per hour, 3,150 kilometers per hour), which earned him the title, “The Fastest Man Alive.” He was the pilot on thirteen of the twenty X-2 flights.
Frank Everest returned to operational assignments in March 1957, commanding the 461st Fighter Squadron, 36th Fighter Wing, equipped with the F-100 Super Sabre, at Hahn Air Base, Germany. Later, Colonel Everest commanded the 4453rd and 4520th Combat Crew Training Wings, and was assigned staff positions at the Pentagon. On 20 November 1963, Colonel Everest, commanding the 4453rd Combat Crew Training Squadron, flew one of the first two operational McDonnell F-4C Phantom II fighters from the factory in St. Louis to MacDill Air Force Base, Florida.
On 1 November 1965, Pete Everest was promoted to the rank of brigadier general. Between 1966 and 1972, General Everest flew 32 combat missions over Southeast Asia.
He served as commander of the Aerospace Rescue and Recovery Service from 1970 to 1973. He retired from the Air Force 1 March 1973 after 33 years of service. PeteEverest later worked as a test pilot for Sikorsky Aircraft.
During his military career, General Everest was awarded the Air Force Distinguished Service Medal; Legion of Merit with two oak leaf clusters (three awards); Distinguished Flying Cross with two oak leaf clusters (three awards); Purple Heart; Air Medal with one silver and two bronze oak leaf clusters (seven awards); Air Force Commendation Medal with one oak leaf cluster (two awards); Presidential Unit Citation with two bronze oak leaf clusters (three awards); Air Force Gallant Unit Citation; Prisoner of War Medal; American Campaign Medal; European-African-Middle Eastern Campaign medal with four bronze stars; Asiatic-Pacific campaign Medal with two bronze stars; World War II Victory Medal; national Defense Service Medal; Armed Forces Expeditionary Medal; Vietnam Service Medal; Air Force Longevity Service Award with one silver and two bronze oak leaf clusters (eight awards); Air Force Small Arms Expert Marksmanship Ribbon; and the Republic of Vietnam Campaign Medal with 1960– device. General Everest was rated as a Command Pilot, and a Basic Parachutist.
Brigadier General Frank Kendall Everest, Jr., United States Air Force, died at Tucson, Arizona, 1 October 2004, at the age of 84 years.
¹ FAI Record File Number 8868: World Record for Speed Over a Straight 15/25 Kilometer Course, 1,215.298 kilometers per hour (755.151 miles per hour)
17 August 1946: First Sergeant Lawrence Lambert, U.S. Army Air Forces, was the first person to eject from an aircraft in flight in the United States.
Lambert was assigned to the Air Material Command Parachute Branch, Personal Equipment Laboratory. He was an 11-year veteran of the Air Corps. During World War II, he served in the Asiatic-Pacific Theater. Previous to this test, Lambert had made 58 parachute jumps.
The test aircraft was a modified Northrop P-61B-5-NO Black Widow night fighter, 42-39498,¹ redesignated XP-61B. The airplane was flown by Captain John W.McGyrt and named Jack in the Box.
The ejection seat was placed in the gunner’s position, just behind and above the Black Widow’s pilot. A 37 mm cartridge fired within a 38 inch (0.97 meter) gun barrel launched the seat from the airplane at approximately 60 feet per second (18.3 meters per second). Lambert experienced 12–14 Gs acceleration.
Flying over Patterson Field at more than 300 miles per hour (483 kilometers per hour) at 6,000 feet (1,829 meters), Lambert fired the ejection seat. He and the seat were propelled approximately 40 feet (12 meters) above the airplane. After 3 seconds, he separated from the seat, and after another 3 seconds of free fall, his parachute opened automatically. Automatic timers fired smaller cartridges to release Lambert from the seat, and to open the parachute.
He later said, ” ‘I lived a thousand years in that minute,” before the pilot, pulled the release. . . ‘ Following the successful jump, blue-eyed, sandy-haired Sgt. Lambert expressed only one desire: To ‘get around the biggest steak available.’ ” —Dayton Daily News, Vol. 70, No. 26, Sunday, 18 August 1946, Society Section, Page 10, Columns 4–6
Sergeant Lawrence parachuted safely. He was awarded the Distinguished Flying Cross. His citation read:
First Sergeant Lawrence Lambert, Air Corps, 6653991, for extraordinary achievement in aerial flight as a volunteer for the test of human ejection from a high speed aircraft, 17 August 1946. His courageous in the face of unknown factors that might have caused serious injury or loss of life, has contributed immeasurably to aeronautical and medical knowledge of the ejection method of escape from the aircraft.
—Air Force Enlisted Heritage Institute, AFEHRI File 19–10
Sergeant Lambert also won the Cheney Award, “for an act of valor, extreme fortitude or self-sacrifice in a humanitarian interest, performed in connection with aircraft, but not necessarily of a military nature.” The medal was presented to him by General Carl A. Spaatz, in a ceremony held at Washington D.C., 15 April 1947.
Master Sergeant Lambert was later involved in rocket sled tests with Colonel John P. Stapp, M.D., Ph.D.
¹ Another source states 42-39489, however, according to Joe Baugher’s serial number web site, this airplane was “condemned to salvage Jul 19, 1945”
