28 October 1952: The prototype Douglas XA3D-1 Skywarrior, Bu. No. 125412, made its first flight at Edwards Air Force Base, California. Douglas test pilot George R. Jansen was in the cockpit.

The Skywarrior was a carrier-based, twin-engine, swept-wing strategic bomber, designed to carry a 12,000 pound (5,443 kilogram) bomb load. The prototype was equipped with two Westinghouse XJ40-WE-12 turbojet engines producing 7,000 pounds of thrust (31.138 kilonewtons), each.

Designed to be launched from an aircraft carrier, fly 2,000 miles (3,219 kilometers), deliver a 3.8 megaton Mark 15 thermonuclear bomb on target, then return to the carrier, the Skywarrior was a considerable challenge for its designers. It was operated by a three man crew: pilot, navigator/bombardier and gunner.

The production A3D-1 was 74 feet, 5 inches (22.682 meters) long with a wingspan of 72 feet, 6 inches (22.098 meters) and overall height of 22 feet, 10 inches (6.960 meters). The shoulder-mounted wings were swept back at a 36° angle and the wings and vertical fin were hinged so that they could be folded for storage aboard the aircraft carrier. The bomber’s empty weight was 35,900 pounds (16,284 kilograms) and the maximum takeoff weight was 70,000 pounds (31,752 kilograms).

When the two prototypes’ Westinghouse JX40 engines proved to be underpowered, they were replaced with Pratt & Whitney J57-P-1 turbojets, rated at 9,000 pounds of thrust (40.034 kilonewtons). The J57 was a two-spool axial-flow turbojet which had a 16-stage compressor section and a 3-stage turbine. (Both had high- and low-pressure stages.) The engine was 15 feet, 3.5 inches (4.661 meters) long, 3 feet, 5.0 inches (1.041 meters) in diameter, and weighed 4,390 pounds (1,991 kilograms). Production models were equipped with the J57-P-6, rated at 9,700 pounds of thrust (43.148 kilonewtons).

The A3D-1 had a cruise speed of 519 miles per hour (835 kilometers per hour) and maximum speed of 621 miles per hour (999 kilometers per hour) at 1,000 feet (305 meters). The combat ceiling was 40,500 feet (12,344 meters). It had a range of 2,100 miles (3,380 kilometers). The combat radius was 1,150 miles (1,851 kilometers).

The Skywarrior could carry 12,000 pounds (5,443 kilograms) of conventional or Special Weapons (MK 43 or MK 57 nuclear bombs) in its internal bomb bay. A remotely-operated turret in the tail was armed with two An-M3 20 mm cannon with 500 rounds per gun.

The first A3D-1 production aircraft were painted a glossy sea blue. This was soon changed to a flat light gray for the sides and upper surfaces with gloss white underneath. This provided better camouflage as well as thermal protection from nuclear blast.

Douglas built 282 A3D Skywarriors between 1956 and 1961. They remained in service as late as 1991. The U.S. Air Force ordered 294 B-66 Destroyer medium bombers, which were developed from the A3D. The first XA3D-1, Bu. No. 125412, was used as a ground trainer after the test flight program was completed.

George R. Jansen was the Director of Flight Operations for the Douglas Aircraft Company. He had been a bomber pilot flying the B-24 Liberator during World War II. After one mission, his bomber, Margaret Ann, returned to base in England with more than 750 bullet and shrapnel holes, and one crewman dead and another wounded. He twice flew missions from North Africa against the refineries at Ploesti, Romania. At the age of 22, Jansen was a major in command of the 68th Bombardment Squadron (Heavy), 44th Bombardment Group (Heavy). He had been awarded three Distinguished Flying Crosses and five Air Medals.

After the war, George Jansen went to work for Douglas as a production test pilot. He graduated from the Air Force Test Pilot School at Edwards Air Force Base in 1952. He flew many of Douglas’s new prototype aircraft, and also flew the modified Boeing P2B-1S Superfortress mother ship to carry the D-558-II Skyrocket to altitude. He made many of the first flights for Douglas, both military and civil. He passed away at the age of 70 years.

28 October 1936: Flying a four-engine Tupolev TB-3 bomber near Tchelcovo, U.S.S.R., Юмашев Андрей Борисович (Andrey Borisovich Yumashev, A.B. Yumashev, A. Youmachev, André Youmacheff), with a crewman named Kalachnikov, set a Fédération Aéronautique Internationale (FAI) World Record for Altitude With a 5,000 Kilogram (11,023 pounds) Payload, reaching 8,980 meters (29,462 feet).¹ This was the fourth world altitude record set by Yumashev with the TB-3.

The transport variant of the Tupolev TB-3 is identified as the ANT-6.

For the 28 October flight, Yumashev’s airplane was powered by four air-cooled, supercharged, 30.104 liter (1,837 cubic inches) Shvetsov ASh-62 nine-cylinder radial engines, rated at 1,000 horsepower at 2,200 r.p.m., each. This engine was developed from the earlier Shvetsov M-25, which was a license-built version of the Wright Aeronautical Corporation R-1820 Cyclone.

The previous month, Andrey Yumashev had set three similar world records. At that time the TB-3 had been powered by four liquid-cooled, supercharged, 46.928 liter (2,863.7 cubic inches) displacement, Mikulin AM-34FRN 60° V-12 engines with gear reduction, rated at 1,200 horsepower at 2,000 r.p.m. Interestingly, this engine had a different piston stroke length for the left and right cylinder banks, resulting in different displacement for each bank. On 11 September, Yumashev had flown the TB-3 to an altitude of 8,116 meters (26,627 feet) with a 5,000 kilogram payload.² On 16 September, he reached 6,605 meters (21,670 feet) while carrying 10,000 kilograms (22,046.23 pounds).³ Finally, on 20 September the Andrey Yumashev and the TB-3, this time with crewman Cheverdinsky, reached 2,000 meters (6,562 feet) with a 12,000 kilogram (26,455.47 pounds) payload.⁴

Soviet Air Force Tupolev TB-3 heavy bombers.

The Tupolev TB-3 was a four-engine heavy bomber built of a steel framework with corrugated steel skin panels. It had fixed landing gear. Initially, each main gear supported two wheels in a bicycle configuration. This was later changed to a single wheel and tire. While most were powered by liquid-cooled V-12 engines, various combinations of propellers were used. Some airplanes used wooden two-bladed propellers, while some used four-bladed propellers on the inner two engines. Later bombers used four-bladed propellers on all engines, while some ANT-6 transports used metal three-bladed variable-pitch propellers.

The first prototype had flown in 1930 and the TB-3 was in service until 1939, by which time it was obsolete. There were still more than 500 when the Great Patriotic War began in 1941. In addition to service as a heavy bomber, it also flew cargo and was a paratroop transport.

Major General Andrey Borisovich Yumashev was born at St. Petersburg, Russian Empire, in March 1902. He entered the army in 1918, serving with artillery units. In 1924 he trained as a pilot, serving as a combat pilot until 1927 when he became a test pilot at the Research and Testing Institute of the Air Force. Over the next ten years he tested fighters, bombers, and transports, and was appointed Test Pilot First Class.

In addition to the four payload-to-altitude world records above, from 12–14 July 1937 he was copilot of a Tupolev ANT-25 which flew from Moscow to San Jacinto, California, across the North Pole.⁵

Yumashev flew the Ilyushin DB-3 long-range bomber during the Soviet Finnish War of 1940 (“The Winter War.”) During the Great Patriotic War, he commanded the 2nd Independent Fighter Aviation Squadron in defense of Moscow, then the 237th Fighter Regiment at the Kalinin Front. He served as deputy commander of the 3rd Air Force at the Kalinin Front and then the 1st Air Army on the Western Front. By the spring of 1943, he was in command of the 6th Fighter Air Corps at the Central front. By 1944, General Yumashev commanded the Eastern Front Air Defense and the Southern Front Air Defense. He participated in the attacks against Königsberg and Berlin at the end of World War II.

A. B. Yumashev retired from the Soviet military in 1946. He then went on to become an accomplished artist.

During his military service, General Yumashev was named Hero of the Soviet Union, twice was awarded the Order of Lenin, and five times the Order of the Red Banner. He was also awarded the Order of the Red Star.

Major General Andrey Borisovich Yumashev died at Moscow, Russia, U.S.S.R., 20 May 1988.

28 October 1925: The court martial of Colonel William (“Billy”) Mitchell, Air Service, United States Army, began at Washington, D.C. For his criticism of the U.S. Navy’s leadership in regard to a number of deadly aviation accidents, he was charged with eight counts of insubordination.

(Mitchell had been returned to his permanent rank of colonel after completing his term as Assistant Chief of the Air Service, during which he retained the temporary rank of brigadier general that he had held during World War I.)

Billy Mitchell had been the senior American air officer in France during World War I. He was a determined advocate for the advancement of military air power and encouraged his officers to compete in air races and attempt to set aviation records to raise the Air Service’ public profile. He gained great notoriety when he bombed and sank several captured German warships to demonstrate the effectiveness of airplanes against ships.

His outspoken advocacy resulted in the famous Court Martial of Billy Mitchell, in which a military court consisting of twelve senior Army officers found Mitchell guilty of insubordination. He was reduced in rank and suspended for five years without pay.

Major General Douglas MacArthur (later, General of the Army, a five-star rank) said that the order to serve on the court was, “. . . one of the most distasteful orders I ever received.”

Mitchell resigned from the Army and continued to advocate for air power. He died in 1936.

After his death, President Franklin D. Roosevelt elevated Billy Mitchell to the rank of Major General on the retired officers list. The North American Aviation B-25 twin-engine medium bomber was named “Mitchell” in recognition of General Mitchell’s efforts to build up the military air capabilities of the United States.

27 October 1961: At 15:06:04 UTC, (10:06 a.m., EST), 3.97 seconds after ignition, the first Saturn C-1 heavy launch vehicle (Saturn I, SA-1) lifted off from Launch Complex 34 at the Cape Canaveral Air Force Station on the east coast of Florida. This was a test of the first stage, only. The rocket’s upper stages were dummies.

At about 109 seconds after liftoff, four inner engines of the first stage shut down, followed 6 seconds later by the outer four. The rocket continued on a ballistic trajectory.

SA-1 reached a maximum speed of 3,607 miles per hour (5,805 kilometers per hour), and a peak altitude of 84.813 miles (136.493 kilometers). It impacted in the Atlantic Ocean 214.727 miles (345.570 kilometers) down range. The duration of the flight was 15 minutes, 0 seconds. The flight was considered to be nearly flawless.

The Saturn C-1 was bigger than any rocket built up to that time. Early versions of the three-stage rocket were 162 feet, 8.90 inches (49.6037meters) tall, with a maximum diameter of 21 feet, 5.0 inches (6.528 meters). The all-up weight was 1,124,000 pounds (509,838 kilograms).

The first stage of SA-1 was built by the Marshall Space Flight Center (MSFC) at Huntsville, Alabama. The S-I stage was built up with a Jupiter rocket fuel tank in the center for liquid oxygen, surrounded by eight Redstone rocket tanks. Four were filled with RP-1 propellant, alternating with four filled with LOx. The first stage was powered by eight Rocketdyne Division H-1 engines rated at 165,000 pounds of thrust (733.96 kilonewtons), each. Total thrust for the first stage was 1,320,000 pounds (5,871.65 kilonewtons). The outer four engines were gimbaled to steer the rocket. (The S-I Block I stage had no fins.)

The first stage had been test fired 20 times before being transported to Cape Canaveral by barge.

For the first flight, SA-1, the S-IV second stage and S-V third stage were dummies. The S-IV was filled with 90,000 pounds (40,823 kilograms) of water for ballast. The S-V third stage, carried 100,000 pounds (45,359 kilograms) of water. Mounted above the third stage was a Jupiter nose cone.

The Saturn C-1 weighed 925,000 pounds (419,573 kilograms). It contained 41,000 gallons (155,200 liters) of RP-1, a refined kerosene fuel, with 66,000 gallons (249,837 liters) of liquid oxygen oxidizer— 600,000 pounds (272,155 kilograms) of propellants.
