21 August 1953: Major Marion E. Carl, United States Marine Corps, flew the number three Douglas D-558-II Skyrocket, Bu. No. 37974, to an altitude 83,235 feet (25,370 meters).¹

The supersonic research rocketplane had been dropped from a Boeing P2B-1S Superfortress at 30,000 feet (9,144 meters) over Edwards Air Force Base. During this flight the Skyrocket reached Mach 1.728.

The Associated Press wire service reported the event:

Altitude Record Set By Hubbard Pilot

     WASHINGTON (AP) —The Navy said Monday Lt. Col. Marion E. Carl, a Marine Corps pilot set a new altitude record of 83,235 feet in the Douglas Skyrocket research plane on Aug. 21.

    The Navy said the unofficial world mark was established during a test of a newly developed high-altitude flying suit. ²

     The previous altitude record was 79,494 feet, set in the same airplane by Douglas test pilot Bill Bridgeman on Aug. 7, 1951.

     A Navy spokesman said Carl is at Edwards Air Force Base, Calif. for an attempt Monday or Tuesday on the speed mark of 1,238 miles an hour set by Bridgeman in the Navy D-558-2 Skyrocket Aug. 1, 1951.

     As in Bridgeman’s altitude and speed record flight, Carl’s runs are being made through aerial launching. The Skyrocket is carried to an altitude of 30,000 feet or better by a B29 “mother plane,” and then released.

     National Aeronautic Assn. rules require that altitude record attempts be launched from the ground and that speed runs be made at specified altitudes.

     For these reasons, none of the Skyrocket records is, or likely to become, official. Some flying authorities have urged that official rules be rewritten to conform to modern developments in flying technique.

     Carl is from Hubbard, Ore. and is stationed at the Quantico, Va., Marine Corps Air Station. He has been assigned as assistant Marine Corps project officer for the national aircraft show at Dayton next week.

     Five Years ago Carl set a world speed mark of 650.8 miles an hour in the Skyrocket’s Navy predecessor, the D-558-1 Skystreak.

The Douglas D-558-II was Phase II of a U.S. Navy/Douglas Aircraft Company/National Advisory Committee on Aeronautics joint research project exploring supersonic flight. It was a swept-wing airplane powered by a single Reaction Motors LR8-RM-6 four-chamber rocket engine. The Skyrocket was fueled with alcohol and liquid oxygen. The engine was rated at 6,000 pounds of thrust (26.69 kilonewtons) at Sea Level.

There were three Phase II aircraft. Originally, they were also equipped with a Westinghouse J34-W-40 turbojet engine which produced 3,000 pounds of thrust (13.35 kilonewtons) and the Skyrockets took off from the surface of Rogers Dry Lake. Once the D-558-II reached altitude, the rocket engine was fired for the speed runs. As higher speeds were required, the program shifted to an air launch from a B-29 (P2B-1S) “mothership”. Without the need to climb to the test altitude, the Skyrocket’s fuel load was available for the high speed runs.

The D-558-II was 42.0 feet (12.80 meters) long, with a wingspan of 25.0 feet (7.62 meters). The leading edge of the wing was swept at a 35° angle and the tail surfaces were swept to 40°. The aircraft weighed 9,421 pounds (4,273 kilograms) empty and had a maximum takeoff weight of 15,787 pounds (7,161 kilograms). It carried 378 gallons (1,431 liters) of water/ethyl alcohol and 345 gallons (1,306 liters) of liquid oxygen.

The mothership, NACA 137, was a Boeing Wichita B-29-95-BW Superfortress, U.S. Air Force serial number 45-21787. It was transferred to the U.S. Navy, redesignated P2B-1S and assigned Bureau of Aeronautics number 84029. Douglas Aircraft modified the bomber for its drop ship role at the El Segundo plant.

Between 4 February 1948 and 28 August 1956, the three rocketplanes made a total of 313 flights.

Marion Eugene Carlwas born at Hubbard, Oregon, 1 November 1915. He was the second of four children of Herman Lee Carl, a dairy farmer, and Ellen Lavine Ellingsen Carl.

Marion E. Carl 1935

Carl graduated from Oregon State College at Corvallis, Oregon, and was commissioned as a second lieutenant in the United States Army Reserve, 31 May 1938. Lieutenant Carl soon resigned this commission to accept an appointment as an Aviation Cadet, United States Navy. He enlisted as a private, first class, Volunteer Marine Corps Reserve, 17 July 1938, and was designated a student Enlisted Naval Aviation Pilot assigned to the Naval Reserve Aviation Base, Squantum, Massachusetts. He entered flight school as an Aviation Cadet at Naval Air Station Pensacola near Pensacola, Florida, 26 July 1938.

After completing flight training, Carl was commissioned as a Second Lieutenant, United States Marine Corps Reserve, 20 October 1939. He was then assigned to Marine Fighting Squadron One (VMF-1) at Brown Field, Quantico, Virginia.

In 1940, Lieutenant Carl returned to NAS Pensacola as a flight instructor. On 25 February 1941, Second Lieutenant Carl, U.S.M.C.R., was appointed a Second Lieutenant, United States Marine Corps.

Lieutenant Carl was transferred to VMF-221 at San Diego, California, as a fighter pilot. The unit was assigned to the aircraft carrier USS Saratoga (CV-3) for transportation to MCAS Ewa, Oahu, Territory of Hawaii. On 25 December 1941, VMF-221 was deployed to Midway Atoll.

Marion Carl and his squadron fought during the Battle of Midway. Flying a Grumman F4F-3 Wildcat, Bu. No. 1864,³ on 4 June 1942, he shot down his first enemy airplane, a Mitsubishi A6M Zero fighter, and damaged two others. Lieutenant Carl was awarded the Navy Cross for his actions in that decisive battle.

Marion Carl was next assigned to VMF-223 under the command of Captain John L. Smith. The Marine fighter squadron was the first air unit to arrive at Henderson Field on the island of Guadalcanal in the Solomons, 20 August 1942. This was a critical airfield, originally built by the Japanese military but occupied by Allied forces. On 26 August, Lieutenant Carl became the Marine Corps’ first “ace.”

Carl was shot down in 9 September 1942 and was missing for five days. He was helped by islanders who eventually returned him to his base.

The squadron departed Guadalcanal 16 October 1942, and sailed to San Francisco, California. VMF-223 was credited with destroying 110½ enemy aircraft. Carl was credited with 16.

Lieutenant Carl married Miss Edna T. Kirvin at New York City, New York, 7 January 1943.

On 26 January, he took command of VMF-223. On 8 May 1943, Lieutenant Carl was promoted to the temporary rank of captain. The squadron was re-equipped with the new Vought-Sikorsky F4U-1 Corsair. Training in the new fighter took place at MCAS El Toro, in southern California.

After the War Marion Carl trained as a test pilot at NAS Patuxent River, Maryland, testing jet aircraft on aircraft carriers and he was also the first Marine Corps pilot to fly a helicopter. He commanded the Marine’s first jet squadron, VMF-122, which flew the McDonnell FH-1 Phantom. He was promoted to lieutenant colonel 7 August 1947.

In May 1955, Colonel Carl commanded Marine Photo Reconnaisance Squadron One (VMJ-1). The squadron flew the McDonnell FH-2 Banshee from air bases on Taiwan on secret missions over the People’s Republic of China.

At Muroc Army Air Field (now Edwards Air Force Base) he tested the Douglas D-558-I Skystreak and D-558-II Skyrocket, setting world records for speed and altitude. He was promoted to colonel, 1 October 1956.

By 1962 Colonel Carl was Director of Marine Corps Aviation. He was promoted to brigadier general, 1 June 1964.

Brigadier General Carl commanded the First Marine Brigade during the Vietnam War and flew combat missions in jet fighters and helicopter gun ships.

Promoted to major general in August 1967, with his date of rank retroactive to 1 June 1964. Carl commanded the 2nd Marine Aircraft Wing, then served as Inspector General of the Marine Corps from 1970 until 1973. When he retired in 1973, General Carl had accumulated more that 13,000 flight hours.

During his military career, Major General Carl was awarded the Navy Cross with two gold stars (three awards); The Legion of Merit with valor device and three gold stars (four awards); The Distinguished Flying Cross with four gold stars (five awards); and the Air Medal with two gold and two silver stars (twelve awards).

Tragically, General Carl was murdered in Roseburg, Oregon, 28 June 1998, as he defended his wife, Edna, during a home-invasion robbery. Mrs. Carl was wounded, but survived.

Major General Marion E. Carl, United States Marine Corps, is buried at Arlington National Cemetery.

¹ No officially-certified altitude record was set during this flight.

² The pressure suit Lieutenant Colonel Carl was testing was a David Clark Co. Model 7 full-pressure suit.

³ Often cited as Grumman F4F-3 Bu. No. 4000 (second bureau number series, 1935–1940) the entry in Carl’s certified pilot logbook for 4 June 1942 states the airplane he flew to shoot down the enemy fighter was F4F-3 Bu. No. 1864.

15 August 1951: Just 8 days after he set an unofficial world speed record of Mach 1.88 (1,245 miles per hour; 2,033.63 kilometers per hour), Douglas Aircraft Company test pilot William Barton (“Bill”) Bridgeman flew the rocket-powered United States Navy/National Advisory Committee on Aeronautics (NACA) Douglas D-558-II Skyrocket, Bu. No. 37974, to a world record altitude at Edwards Air Force Base in the high desert of Southern California.

The Skyrocket was airdropped at 34,000 feet (10,363 meters) from a highly-modified U.S. Navy P2B-1S Superfortress, Bu. No. 84029. The mother ship was a U.S. Air Force Boeing B-29-95-BW Superfortress, 45-21787, transferred to the Navy and flown by another Douglas test pilot, George R. Jansen.

The flight plan was for Bridgeman to fire the rocket engine and allow the Skyrocket to accelerate to 0.85 Mach while climbing. The Skyrocket was powered by a Reaction Motors LR8-RM-6 engine, which produced 6,000 pounds of thrust. As the rocketplane continued to accelerate to Mach 1.12, the test pilot was to pull up, increasing the angle of climb while holding an acceleration rate of 1.2 Gs. This would result in a constantly increasing angle of climb. When it reached 50°, Bridgeman was to maintain that, climbing and accelerating, until the rocket engine ran out of fuel.

Initially, the plan was to continue climbing after engine shutdown until the D-558-II was approaching stall at the highest altitude it could reach while on a ballistic trajectory. There were differing expert opinions as to how it would behave in the ever thinner atmosphere. On the morning of the flight, Douglas’ Chief Engineer, Ed Heinemann, ordered that Bridgeman push over immediately when the engine stopped.

Bill Bridgeman stuck to the engineers’ flight plan. As the Skyrocket accelerated through 63,000 feet (19,200 meters), it started to roll to the left. He countered with aileron input, but control was diminishing in the thin air. The next time it began there was no response to the ailerons. Bridgeman found that he had to lower the Skyrocket’s nose until it responded, then he was able to increase the pitch angle again. At 70,000 feet (21,336 meters), travelling Mach 1.4, he decided he had to decrease the pitch angle or lose control. Finally at 76,000 feet (23,165 meters), the engine stopped. Following Heinemann’s order, Bridgeman pushed the nose down and the D-558-II went over the top of its arc at just 0.5 G.

“In the arc she picks up a couple of thousand feet. The altimeter stops its steady reeling and swings sickly around 80,000 feet. The altitude is too extreme for the instrument to function.

“Eighty thousand feet. It is intensely bright outside; the contrast of the dark shadows in the cockpit is extreme and strange. It is so dark lower in the cockpit that I cannot read the instruments sunk low on the panel. The dials on top, in the light, are vividly apparent. There seems to be no reflection. It is all black or white, apparent or non-apparent. No half-tones. It is a pure, immaculate world here.

“She levels off silently. I roll right and there it is. Out of the tiny windows slits there is the earth, wiped clean of civilization, a vast relief map with papier-mâché mountains and mirrored lakes and seas. . . .

“It is as if I am the only living thing connected to this totally strange, uninhabited planet 15 miles below me. The plane that carries me and I are one and alone.”

The Lonely Sky, William Bridgeman with Jacqueline Hazard, Castle and Company LTD, London, 1956, Chapter XXII at Page 268.

After the data was analyzed, it was determined that William Bridgeman and the Douglas Skyrocket had climbed to 79,494 feet (24,230 meters), higher than any man had gone before. This was the last flight that would be made with a Douglas test pilot. The rocketplane was turned over to NACA, which would assign it the number NACA 144.

Bill Bridgeman had been a Naval Aviator during World War II, flying the Consolidated PBY Catalina and PB4Y (B-24) Liberator long range bombers with Bombing Squadron 109 (VB-109), “The Reluctant Raiders.” Bridgeman stayed in the Navy for two years after the war, then he flew for Trans-Pacific Air Lines in the Hawaiian Islands and Pacific Southwest Airlines in San Francisco, before joining Douglas Aircraft Co. as a production test pilot, testing new AD Skyraiders as they came off the assembly line at El Segundo, California. He soon was asked to take over test flying the D-558-2 Skyrocket test program at Muroc Air Force Base.

The D-558-II Skyrocket was Phase II of a planned three phase experimental flight program. It was designed to investigate flight in the transonic and supersonic range. It was 46 feet, 9 inches (14.249 meters) long with a 25 foot (7.62 meter) wing span. The wings were swept back to a 35° angle. The Skyrocket was powered by a Westinghouse J34-WE-40 11-stage axial-flow turbojet engine, producing 3,000 pounds of thrust, and a Reaction Motors LR8-RM-6 four-chamber rocket engine, which produced 6,000 pounds of thrust. The rocket engine burned alcohol and liquid oxygen.

There were three D-558-2 Skyrockets. Between 4 February 1948 and 28 August 1956, they made a total of 313 flights. Bill Bridgeman’s speed and altitude record-setting Skyrocket, Bu. No. 37974, NACA 144, is in the collection of the Smithsonian Institution National Air and Space Museum.

12 August 1960: At Edwards Air Force Base, California, Major Robert M. White flew the North American Aviation X-15 rocketplane to an altitude of 136,500 feet (41,605 meters), exceeding the previous unofficial record of 126,200 feet (38,466 meters) set by the late Captain Iven C. Kincheloe, Jr., with the Bell X-2, 7 September 1956.

Iven Kincheloe had been assigned as the Air Force’s project pilot for the X-15. When he was killed on a routine flight, Bob White was designated to replace him.

This was White’s fourth flight in an X-15, and the 19th flight of the X-15 Program. The Number 1 rocketplane, serial number 56-6670, was carried aloft under the right wing of the “mothership,” Boeing NB-52A Stratofortress 52-003. At 08:48:43.0 a.m., PDT, 56-6670 was dropped over Silver Lake, near the Nevada-California border. White fired the two Reaction Motors XLR11-RM-13 rocket engines and they burned for 256.2 seconds.

This flight took place in Phase II of the Program and was intended to gradually increase the envelope of X-15 performance with the XLR11 engines while waiting for the much more powerful XLR99. The purpose of Flight 19 was to reach maximum altitude in order to test the rocketplane’s stability and controllability above the atmosphere.

The X-15 accelerated to Mach 2.52, 1,773 miles per hour (2,853 kilometers per hour) while climbing at nearly a 70° angle and reached a peak altitude of 136,500 feet (41,605 meters). After engine shutdown, White glided to a landing on Rogers Dry Lake and touched down. The duration of the flight was 11 minutes, 39.1 seconds.

Neither Kincheloe’s or White’s altitudes are recognized as records by the Fédération Aéronautique Internationale(FAI). Over the next few years, the X-15 would reach to nearly three times higher.

7 August 1963: The first Lockheed YF-12A interceptor, 60-6934, took off from a top secret air base at Groom Lake, Nevada, on its first flight. Lockheed test pilot James D. Eastham was at the controls.

Three YF-12A prototypes s were built. They were Mach 3+ interceptors developed from the Central Intelligence Agency “Oxcart” Lockheed A-12 reconnaissance airplane.

The interceptors were equipped with a very effective Hughes fire control system and armed with three Hughes AIM-47 Falcon air-to-air missiles. In 1965 the U.S. Air Force placed an order for 93 F-12B interceptors for the Air Defense Command, but Secretary of Defense Robert McNamara continually refused to release the funds which Congress had appropriated. Eventually the contract was cancelled.

In testing, a YF-12A launched a Falcon missile while flying at Mach 3.2 at 74,000 feet (22,555 meters). It successfully intercepted and destroyed a target drone flying at only 500 feet (152 meters).

60-6934 was damaged beyond repair in a runway accident at Edwards Air Force Base, 14 August 1966. Part of the airplane was salvaged and used to construct the only SR-71C, 64-17981, a two-seat trainer. The third YF-12A, 60-6936, was destroyed when the crew ejected during an inflight fire near Edwards AFB, 24 June 1971. The only remaining YF-12A, 60-6935, is in the collection of the National Museum of the United States Air Force, Wright-Patterson AFB, Ohio.

31 July 1901

(Bröckelmann (Hrsg): Wir Luftschiffer, Ullstein, 1909)

31 July 1901: At “10 minutes before 11 in the morning,” the gas balloon Preussen (Prussia) began to ascend from Tempelhofer Felde at Berlin, capital city of the Königreich Preußen (Kingdom of Prussia) and the German Empire.

Reinhard Joachim Süring, 1907

Carried aloft in the open gondola were two men, Reinhard Joachim Süring of the Prussian Meteorological Institute, and Josef Arthur Stanislas Berson.

There was a light wind from the northwest, and the air temperature was 23.4 °C. (74.1 °F.). The air pressure was 762.0 millimeters (30.0 inches) of Mercury.

The balloon was made by Continental Caoutchouk und Guttapercha-Compagnie, Hannover, at a cost of 20,000ℳ. To inflate the balloon at the airfield, 1,080 pressurized cylinders containing 5,400 cubic meters (190,700 cubic feet) of hydrogen were used. When fully inflated at altitude, the spherical envelope had a maximum volume of 8,400 cubic meters (296,643 cubic feet).

Josef Arthur Stanislas Berson, 1901

In the gondola were four 1,000 liter (35 cubic foot) cylinders of oxygen for breathing, and 8,000 kilograms (17,637 pounds) pounds of ballast contained in 63 kilogram (139 pound) sand bags and 36 kilogram (79 pound) bags of iron filings.

Süring and Berson reached an altitude of 5,000 meters (16,404 feet) in 40 minutes. The air  temperature was -7 °C. (19.4  °F.). The envelope had reached its maximum volume by this time.

After 3 hours, Preussen had ascended to 8,000 meters (26,247 feet), and in four hours, it reached 9,000 meters (29,528 feet). There, the air temperature was -32 °C. (-25.6 °F.).

The aeronauts had run out of breathing oxygen at 8,170 meters (26,804 feet).

The last observed altitude the men reached was 10,225 meters (33,547 feet), with an air temperature of -35.7 °C. (-32.3 °F.). Josef Berson saw Süring lose consciousness and pulled the emergency valve to vent gas from the balloon and start its descent. He too lost conciousness due to hypoxia.

“. . . dass der Ballon noch kurz nachdem auch der zweite Korbinsasse bei 10500 m das Bewussstein verloren hatte, um mindestens 300 weitere Meter stieg, sonit Maximalhöhe von sicherlich 10800 m (vielleicht 11000 m) erreicht und hierauf unfer Nachwirkung des Ventilzuges in ein jahes Fallen umbog.

[Google English translation: “Shortly after the second basket occupant had lost the awareness stone at 10500 m, the balloon rose at least 300 meters further, reaching a maximum height of certainly 10800 m (perhaps 11000 m), and then reversed our after-effect of the valve train into a sudden fall.]

Both men regained consciousness at about 6,000 meters, but were unable to regain control of the ballon’s descent until 2,500 meters. Süring and Berson returned to Earth near Briesen, Kreis Cottbus, Germany, at 18:25 that evening. The total duration of their flight was 7 hours, 36 minutes.
