5 October 1954: Chief Engineering Test Pilot Tony LeVier made the first flight in the second prototype Lockheed XF-104 Starfighter, 53-7787, at Edwards Air Force Base in the high desert of southern California. This was the armament test aircraft and was equipped with a General Electric T171 Vulcan 20mm Gatling gun. This six-barreled gun was capable of firing at a rate of 6,000 rounds per minute.
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 prototypes had an empty weight of 11,500 pounds (5,216 kilograms) and maximum takeoff weight of 15,700 pounds (7,121 kilograms).
While the first prototype, 53-7776, was equipped with a Buick J65-B-3 turbojet engine, the second used a Wright Aeronautical Division J65-W-6 with afterburner. Both were improved derivatives of the Armstrong Siddely Sa.6 Sapphire, built under license. The J65 was a single-shaft axial-flow turbojet with a 13-stage compressor and 2-stage turbine. The J65-B-3 was rated at 7,330 pounds of thrust, and the J65-W-6, rated at 7,800 pounds (34.70 kilonewtons), and 10,500 pounds (46.71 kilonewtons) with afterburner.
The XF-104 had a maximum speed of 1,324 miles per hour (2,131 kilometers per hour), a range of 800 miles (1,287 kilometers) and a service ceiling of 50,500 feet (15,392 meters).
53-7787 was lost 19 April 1955 when it suffered explosive decompression at 47,000 feet (14,326 meters) during a test of the T171 Vulcan gun system. The lower escape hatch had come loose due to an inadequate latching mechanism. Lockheed test pilot Herman R. (“Fish”) Salmon was unable to find a suitable landing area and ejected at 250 knots (288 miles per hour/463 kilometers per hour) and 15,000 feet (4,572 meters). The XF-104 crashed 72 miles (117 kilometers) east-northeast of Edwards Air Force Base. Salmon was found two hours later, uninjured, about 2 miles (3.2 kilometers) from the crash site.

The YF-104A pre-production aircraft and subsequent F-104A production aircraft had many improvements over the two XF-104 prototypes. The fuselage was lengthened 5 feet, 6 inches (1.68 meters). The J65 engine was replaced with a more powerful General Electric J79-GE-3 turbojet. There were fixed inlet cones added to control airflow into the engines. A ventral fin was added to improve stability.

3 October 1967: The 188th flight of the X-15 Program was the 53rd for the Number 2 aircraft, 56-6671. It had been extensively modified by North American Aviation to an X-15A-2 configuration following a landing accident which had occurred 9 November 1962. The fuselage was lengthened 28 inches (0.711 meters) to accommodate a liquid hydrogen fuel tank for a scramjet engine that would be added to the ventral fin, a new tank for additional hydrogen peroxide to generate steam for the rocket engine turbo pump, and external propellant tanks to allow the rocketplane to reach higher speeds and altitudes. The entire surface of the X-15 was covered with an ablative coating to protect the metal structure from the extreme heat it would encounter on this flight.
Minor issues delayed the takeoff but finally, after they were corrected, and with Pete Knight in the X-15’s cockpit, it was carried aloft under the right wing of Balls 8, a Boeing NB-52B Stratofortress, 52-008.
At 45,000 feet (13,716 meters) over Mud Lake, Nevada, the X-15 was droppeded at 14:31:50.9 local time. Knight fired the Reaction Motors XLR99-RM-1 rocket engine and began to climb and accelerate. After 60 seconds, the ammonia and liquid oxygen propellants in the external tanks was exhausted, so the the tanks were jettisoned to eliminate their weight and aerodynamic drag.
The X-15A-2 climbed to 102,100 feet (31,120 meters) and Pete Knight leveled off, still accelerating. After 140.7 seconds of engine burn, Knight shut the XLR99 down. He noticed that thrust seemed to decrease gradually and the X-15 continued to accelerate to 6,630 feet per second (2,021 meters per second), or Mach 6.72.

Shock waves from the dummy scramjet mounted on the ventral fin impinged on the fin’s leading edge and the lower fuselage, raising surface temperatures to 2,700 °F. (1,482 °C.) The Inconel X structure started to melt and burn through.
Pete Knight entered the high key over Rogers Dry Lake at 55,000 feet (16,764 meters) and Mach 2.2, higher and faster than normal. As he circled to line up for Runway One Eight, drag from the scramjet caused the X-15 to descend faster and this set him up for a perfect approach and landing. Because of heat damage, the scramjet broke loose and fell away from the X-15.
Knight touched down after an 8 minute, 17.0 second flight. His 4,520 mile per hour (7,274 kilometers per hour) maximum speed is a record that still stands.

The X-15A-2 suffered considerable damage from this hypersonic flight. It was returned to North American for repairs, but before they were completed, the X-15 Program came to an end. This was 56-6671’s last flight. It was sent to the National Museum of the United States Air Force where it is part of the permanent collection.
In a ceremony at the White House, President Lyndon B. Johnson presented the Harmon International Trophy to Major William J. Knight.

Mercury-Atlas 8 lifts off from Launch Complex 14, Cape Canaveral Air Force Station, Cape Canaveral, Florida, 12:15:12 UTC, 3 October 1962. (NASA)
3 October 1962: At 08:15:12 a.m., Eastern Daylight Time, Commander Walter M. Schirra, Jr., United States Navy, lifted off from Cape Canaveral, Florida, aboard Mercury-Atlas 8 (MA-8). This was the fifth U.S. manned space flight and the third orbital flight.
The spacecraft, which Wally Schirra had named Sigma 7, entered a low earth orbit with the altitude varying from 84 nautical miles (156 kilometers) to 154 nautical miles (285 kilometers). Each orbit took 88 minutes, 54.6 seconds.
Schirra experimented with the manual flight control systems, took photographs and performed spatial-orientation exercises. There were some difficulties with the cooling of his pressure suit.

Sigma 7 completed 6 orbits and at T+8:52, fired the retro rockets to de-orbit. Reentry was successful and Sigma 7 landed within 0.5 miles (0.8 kilometers) of the primary recovery ship, the aircraft carrier USS Kearsarge (CVS-33).
The Mercury spacecraft, named Sigma 7, was built by McDonnell Aircraft Corporation, St. Louis, Missouri. It was the 16th Mercury capsule built. Designed to carry one pilot, it could be controlled in pitch, roll and yaw by thrusters. It was 9 feet, 7.72 inches (2.939 meters) long, and, bell-shaped, had a maximum diameter of 6 feet, 2.5 inches (1.885 meters). The spacecraft weighed 2,700 pounds (1,224.7 kilograms) at launch.

The rocket, a “1-½ stage”, liquid-fueled Atlas LV-3B, number 113-D, was built by Convair at San Diego, California. It was developed from a U.S. Air Force Atlas D intercontinental ballistic missile, modified for use as a “man-rated” orbital launch vehicle. The LV-3B was 94.3 feet (28.7 meters) tall with a maximum diameter of 10.0 feet (3.05 meters). When ready for launch it weighed 260,000 pounds (120,000 kilograms) and could place a 1,360 kilogram payload into Low Earth orbit. The Atlas’ three engines were built by the Rocketdyne Division of North American Aviation, Canoga Park, California. The XLR89 booster had two 150,000 pound thrust chambers, and the LR105 sustainer engine produced 57,000 pounds of thrust. The rocket was fueled by a highly-refined kerosene, RP-1, with liquid oxygen as the oxidizer.

Schirra was the first astronaut to wear an Omega Speedmaster chronograph during spaceflight. (Omega Reference No. CK2998). The Speedmaster would become flight-qualified by NASA, and the Speedmaster Professional is known as the “moon watch.”
Sigma 7 is on display at the U.S. Astronaut Hall of Fame, Titusville, Florida, near the Kennedy Space Center.
Wally Schirra commanded Gemini 6A during the orbital rendezvous mission with Gemini 7. Later, he commanded Apollo 7, an 11-day orbital mission.

Lieutenant Commander James B. Verdin, United States Navy. (J. R. Eyerman)
3 October 1953: Lieutenant Commander James B. Verdin, United States Navy, a test pilot assigned to NAS Patuxent River, Maryland, flew the second prototype of the Douglas Aircraft Company’s XF4D-1 Skyray, Bu. No. 124587, over a three kilometer course at the Salton Sea, California. Flying at approximately 150 feet (46 meters), Commander Verdin made four passes, with two in each direction. He set a new Fédération Aéronautique Internationale (FAI) World Record for Speed over a 3-kilometer course, averaging 1,211.75 kilometers per hour (752.95 miles per hour).¹
The surface of the Salton Sea, is 236 feet (72 meters) below Sea Level. The air temperature at the time of Verdin’s flight was 98.5 °F. (36.9 °C.). His four runs were measured at 1,200.691, 1,225.377, 1,200.656, and 1,222.294 kilometers per hour (746.075, 761.414, 746.053 and 759.498 miles per hour). The total elapsed time for the flight, from take off to landing at NAS El Centro, was 20 minutes, 25 seconds. The XF4D-1 burned 575 gallons (2,177 liters) of fuel.
Verdin had broken the record set 25 September 1953 by Michael J. Lithgow, chief test pilot for Vickers Supermarine, flying a Supermarine Swift F. Mk.4, WK198, at Castel Idris, Libya.²
In an interview with famed writer Bob Considine for his newspaper column, Verdin said,
“Douglas had its high priced help there at the course, and they iced my fuel for the Skyray while I took a look at the course from a Grumman Cougar,” he remembered. “They ice the fuel because that shrinks it and you can pack more in.
“We towed her out to the starting line to save the stuff. Didn’t even use blocks on the wheels after the engine was started. Just started rolling. I was in the air a little over a minute after the engine started, and headed for the measured course, 40 miles away.
“It was marked for me by smudge pots and burning tires, and orange-red markers to tell me when to turn off my afterburner, which eats fuel like crazy. About five miles short of the line I was doing 620 and turned on the afterburner. It gave me another hundred miles an hour right away, and I held her steady and low over the course. It doesn’t take long. . . about nine seconds for the just under two miles.”

Douglas XF4D-1 Skyray Bu.No. 124587. (U.S. Navy)
The Douglas XF4D-1 Skyray was a single-place, single-engine delta-winged fighter powered by a turbojet engine. It had retractable tricycle landing gear and was to operate off of the U.S. Navy’s aircraft carriers as a high altitude interceptor. The Skyray was designed by the legendary Ed Heinemann, for which he was awarded the Collier Trophy in 1954. Two prototypes were built (Bu.Nos. 124586, 124587). It was a delta-winged aircraft, though the wingtips were significantly rounded.
The Douglas F4D-1 Skyray was 45 feet, 4¾ inches (13.837 meters) long, with a wingspan of 33 feet, 6 inches (10.211 meters) and overall height of 13 feet, 8 inches (4.166 meters). The empty weight was 16,024 pounds (7,268 kilograms) and maximum takeoff weight was 27,116 pounds (12,300 kilograms).
Originally built with Allison J35-A-17 turbojet engines, both prototypes later had a Westinghouse J40-WE-8 afterburning turbojet installed. The Skyray was equipped with the Westinghouse engine when it set the speed record. Production Skyrays used a Pratt & Whitney J57-P-8 afterburning turbojet.
The Westinghouse J40-W-8 was a single-shaft, axial-flow, afterburning turbojet engine with an 11-stage compressor and two-stage turbine. It produced 10,500 pounds of thrust (46.706 kilonewtons) at 7,600 r.p.m. The engine was 25 feet, 0 inches (7.620 meters) long, 3 feet, 4 inches (1.016 meters) in diameter and weighed 3,500 pounds (1,588 kilograms).

The F4D-1 was the first U.S. Navy fighter able to reach supersonic speeds in level flight. The production aircraft had a maximum speed of 722 miles per hour (1,162 kilometers per hour), and service ceiling of 55,000 feet (16.764 meters). Its rate of climb was 18,300 feet per minute (92.97 meters per second) and the maximum range was 1,200 miles (1,931 kilometers).
The Skyray was armed with four 20 mm Colt Mk 12 autocannon, with 65 rounds of ammunition per gun. It could also carry 2.75-inch FFAR rockets, four AIM-9 Sidewinder air-to-air missiles, or two 2,000 pound (1,588 kilogram) bombs.
The Douglas Aircraft Company built 420 F4D-1 Skyrays. They were in service with the U.S. Navy and U.S. Marine Corps from 1956 until 1964.

The record-setting XF4D-1 was transferred to General Electric in July 1955 and used to test GE’s J79 afterburning turbojet engine and the commercial CJ805.
XF4D-1 Bu. No. 124587 was returned to the Navy in May 1960. It is on display at the U.S. Navy Museum of Armament and Technology, NAWS China Lake, California.
Lieutenant Commander James B. Verdin, USN (1918–1955)
James Bernard Verdin was born at Miles City, Montana, 23 February 1918, the son of James Harris Verdin, a farmer, and Nellie Cambron Verdin.
He attended Abraham Lincoln High School in Council Bluffs, Iowa, graduating in 1937, then studied at Iowa State College, Ames, Iowa. He was a member of the Reserve Officers Training Corps (ROTC), and the Theta Chi (ΘΧ) fraternity.
In 1940, Verdin was employed by the Standard Varnish Works, in Chicago, Illinois. He registered for Selective Service (conscription) 16 October 1940. He was described as being 5 feet, 9 inches (1.75 meters) tall, and weighing 160 pounds (72.6 kilograms). He had black hair, brown eyes, and a dark complexion.
He entered the United States Navy as a Seaman, 2nd Class, 11 July 1941. His enlistment was terminated 7 January 1942 and he was accepted as an Aviation Cadet. He was assigned to NAS Corpus Christi, Texas, for flight training. Verdin was commissioned as an Ensign, 18 June 1942.
Miss Kathryn Jane Marschner
Ensign Verdin married Miss Kathryn Jane Marschner at St. Michael’s Church, Pensacola, Florida, 4 August 1942. The ceremony was officiated by Rev. W. J Cusik. They lived in Coronado, California, near NAS North Island. They had one child. They divorced in 1948. Later, he married his second wife, Miss Muriel Carolyn Larson. They had three children and lived in Brentwood, California.
He was promoted to Lieutenant (Junior Grade), 1 May 1943, and then promoted to Lieutenant, 1 July 1944.
During World War II, Lieutenant James Bernard Verdin, U.S.N., was a fighter pilot flying the Grumman F6F-5 Hellcat, assigned to VF-20 aboard USS Enterprise (CV-6). He was awarded the Navy Cross for extraordinary heroism at the Battle of Leyte Gulf, 25 October 1944:

Albert Scott Crossfield, Jr., Aeronautical Engineer and Test Pilot, 1921–2006. (Jet Pilot Overseas)
Albert Scott Crossfield, Jr., was born at Berkeley, California, 2 October 1921, the second of three children of Albert Scott Crossfield and Lucia Dwyer Scott Crossfield. (“Scott Crossfield” is the family name, going back for many generations.) His father was a chemist who was the superintendent of the Union Oil Refinery in Wilmington, California. At the age of 5 years, the younger Scott Crossfield contracted pneumonia. He was comatose for a time and not expected to survive. When he finally began to recover, he was confined to bed for many months. The effects of this illness lasted throughout his childhood.
It was during this time that he developed his interest in aviation. He learned to draw, studied airplanes, and built scale models. Charles F. (“Carl”) Lienesch, who was a pilot for the Union Oil Company, gave Scotty his first ride aboard an airplane at age 6. As a teenager, he took flight lessons in an Inland Sportster at the Wilmington Airport.

After his family bought a farm in Oregon, Scott Crossfield continued flight lessons and soloed a Curtis Robin at the age of 15. He earned his private pilot certificate at 18. After graduating from high school, “Scotty” helped his father with the family farm before attending the University of Washington as a student of aeronautical engineering. He took a job at Boeing to pay his tuition and support.
Ensign A. S. Crossfield, Jr.
After America’s entry into World War II, Scott Crossfield enlisted in the U.S. Army Air Corps as an aviation cadet, but because of expected delays in training, quickly transferred to the U.S. Navy. He enlisted as a Seaman 2/c in the Navy’s V-5 Program at the Naval Reserve Aviation Base, Seattle, Washington, on 21 February 1942. He began Primary Flight Training there, 7 May 1942. Scotty completed military flight training and was commissioned an Ensign, United States Navy, in December 1942.
On 21 April 1943, Ensign Albert Scott Crossfield, U.S. Navy, married Miss Alice Virginia Knoph at Corpus Christi, Texas.
Promoted to lieutenant (junior grade) with date of precedence 21 March 1944.
During World War II, Scott Crossfield served as a fighter pilot, flight and gunnery instructor, flying the Chance Vought F4U Corsair and Grumman F6F Hellcat. Though he was assigned to Fighting Squadron FIFTY-ONE (VF-51) aboard the Independence-class light aircraft carrier USS Langley (CVL-27), he did not serve in combat. He was promoted to the rank of lieutenant 1 August 1945. Scotty was released from active duty 31 December 1945. After the war he joined a Naval Reserve squadron and flew the Goodyear Aircraft Co. FG-1D Corsair at NAS Sand Point, Washington.

In 1950 Scott Crossfield joined the National Advisory Committee for Aeronautics (NACA, the predecessor of NASA) as an Aeronautical Research Pilot at the NACA High Speed Flight Station, Edwards Air Force Base, California. He flew many high-performance jet aircraft like the North American Aviation F-100 Super Sabre, and experimental airplanes such as the Convair XF-92, Douglas X-3, Bell X-4 and X-5. He also flew the research rocket planes, making 10 rocket flights in the Bell X-1 and 77 in the Douglas D-558-II Skyrocket.

On 20 November 1953, Scott Crossfield became the first pilot to fly faster than twice the speed of sound (Mach 2). The D-558-II was carried aloft by a Boeing P2B-1S Superfortress drop ship (a four-engine B-29 long range heavy bomber which had been transferred from the U.S. Air Force to the Navy, then heavily modified by Douglas) to 32,000 feet (9,754 meters) and then released. Scotty fired the LR8 rocket engine and climbed to 72,000 feet (21,945 meters). He put the Skyrocket into a shallow dive and, still accelerating, passed Mach 2 at 62,000 feet (18,898 meters). After the rocket engine’s fuel was expended, he flew the rocketplane to a glide landing on Rogers Dry Lake.
In 1955 Crossfield left NACA and joined North American Aviation, Inc., as Chief Engineering Test Pilot. He planned and participated in the design and operation of the X-15 hypersonic research rocketplane for the Air Force and NASA. He also worked closely with the David Clark Co., in the development of the project’s full-pressure suits.

Milton O. Thompson, another X-15 test pilot, wrote in At the Edge of Space,
“. . . he was intimately involved in the design of the aircraft and contributed immensely to the success of the design, as a result of his extensive rocket airplane experience. . . Scott was responsible for a number of other excellent operational and safety features built into the aircraft. Thus, one might give Scott credit for much of the success of the flight program. . . .”

In 1959–1960, Scott Crossfield flew all of the contractor’s demonstration phase flights for the X-15, including 16 captive carry flights under the wing of the NB-52A Stratofortress while systems were tested and evaluated, one glide flight, and thirteen powered flights. He reached a a maximum altitude of 88,116 feet (26,858 meters) on Flight 6, and a maximum speed of Mach 2.97 (1,960 miles per hour/3,154 kilometers per hour) on Flight 26. The X-15 was then turned over to NASA and the Air Force. The X-15 Program involved a total of 199 flights from 1959 until 1968.

After leaving the X-15 Program, Scott Crossfield continued as a Systems Director with North American Aviation, Inc., working on the Apollo Command and Service Module and the S-IVB second stage of the Saturn V rocket. He left North American in the late ’60s and served as an executive with Eastern Air Lines and Hawker Siddeley. He also continued as a aeronautical engineering consultant to private industry and government.
Among many other awards, Scott Crossfield was received the Harmon Trophy, the Collier Trophy, and the Iven C. Kincheloe Award of the Society of Experimental Test Pilots..

In 1980 Crossfield resumed flying when he purchased a 1960 Cessna 210A Centurion, N6579X, serial number 21057579. This was a single-engine, four-place light airplane, powered by an air-cooled Continental six-cylinder engine. He had flown more than 2,000 hours in this airplane when it crashed during a severe thunderstorm, 19 April 2006, while on a flight from Prattville, Alabama, to Manassas, Virginia.
Albert Scott Crossfield, Jr., was killed. His remains are interred at the Arlington National Cemetery, Arlington, Virginia.
