5 January 1956: The prototype Piasecki Helicopter Company YH-16A-PH Transporter twin-turboshaft, tandem-rotor helicopter, serial number 50-1270, was returning to Philadelphia from a test flight, when, at approximately 3:55 p.m., the aft rotor desynchronized, collided with the forward rotor and the aircraft broke up in flight. It crashed at the Mattson Farm on Oldman’s Creek Road, near Swedesboro, New Jersey, and was completely destroyed.
Test pilots Harold W. Peterson and George Callahan were killed.
It was determined that a bearing associated with an internal coaxial shaft supporting test data equipment had seized, causing the rotor shaft to fail.

At the time, the YH-16 was the largest helicopter in the world. The United States Air Force intended it as a very-long-range rescue helicopter, while the U.S. Army expected it to serve as a heavy lift cargo and troop transport.
The YH-16A had a fuselage length of 78 feet (23.774 meters), and both main rotors were 82 feet (24.994 meters) in diameter. With rotors turning, the overall length was 134 feet (40.843 meters). Their operating speed was 125 r.p.m. Overall height of the helicopter was 25 feet (7.62 meters). The helicopter’s empty weight was 22,506 pounds (10,209 kilograms) and the gross weight was 33,577 pounds (15,230 kilograms).
YH-16 50-1269 was powered by two 2,181.2-cubic-inch-displacement (35.74 liter) air-cooled, supercharged Pratt & Whitney Twin Wasp E2 (R-2180-11) two-row, fourteen-cylinder radial engines with a Normal Power Rating of 1,300 horsepower at 2,600 r.p.m. at 8,000 feet (2,438 meters), and 1,650 horsepower at 2,600 r.p.m., for Takeoff.

The second YH-16A, 50-1270, was modified while under construction and was powered by two Allison Division YT38-A-10 turboshaft engines which produced 1,800 shaft horsepower, each. This made the YH-16A the world’s first twin-engine turbine-powered helicopter.

The cruise speed of the YH-16A was 146 miles per hour (235 kilometers per hour). In July 1955, Peterson and Callahan had flown 50-1270 to an unofficial record speed of 165.8 miles per hour (266.83 kilometers per hour). The service ceiling was 19,100 feet (5,822 meters) and the maximum range for a rescue mission was planned at 1,432 miles (2,305 kilometers).
After the accident, the H-16 project was cancelled.

MEDAL OF HONOR
KENNETH N. WALKER (Air Mission)
Rank and organization: Brigadier General, U.S. Army Air Corps, Commander of V Bomber Command.
Place and date: Rabaul, New Britain, 5 January 1943.
Entered service at: Colorado.
Birth: Cerrillos, New Mexico
G.O. No.: 13, 11 March 1943.
Citation:
For conspicuous leadership above and beyond the call of duty involving personal valor and intrepidity at an extreme hazard to life. As commander of the 5th Bomber Command during the period from 5 September 1942, to 5 January 1943, Brig. Gen. Walker repeatedly accompanied his units on bombing missions deep into enemy-held territory. From the lessons personally gained under combat conditions, he developed a highly efficient technique for bombing when opposed by enemy fighter airplanes and by antiaircraft fire. On 5 January 1943, in the face of extremely heavy antiaircraft fire and determined opposition by enemy fighters, he led an effective daylight bombing attack against shipping in the harbor at Rabaul, New Britain, which resulted in direct hits on 9 enemy vessels. During this action his airplane was disabled and forced down by the attack of an overwhelming number of enemy fighters.

On the morning of 5 January 1943, six Boeing B-17 Flying Fortress and six Consolidated B-24 Liberator heavy bombers departed 7 Mile Drome, an airfield near Port Moresby at the eastern end of the island of New Guinea. Their mission was to attack an enemy shipping convoy believed to be approaching the Japanese military base at Rabaul on the neighboring island of New Britain.
Leading the attack force was B-17 41-24458, San Antonio Rose, flown by Major Allen Lindberg, commanding officer, 64th Bombardment Squadron (Heavy) and Captain Benton Hayes Daniel, Jr. Also on board as observers were Lieutenant Colonel Jack Bleasdale, the executive officer of the 43rd Bombardment Group (Heavy), and Brigadier General Kenneth Newton Walker, commanding general, V Bomber Command, Fifth Air Force. There were a total of 11 airmen on board.¹

The bombers arrived over Rabaul at 8,500 feet (2,591 meters) at 12:00 p.m., local time, and the formation broke up to make individual attacks against the ships in the harbor. Anti-aircraft artillery fire was light and ineffective. The bomber crews claimed several ships sunk and damaged.²
As the bombing force left the target, it was attacked by enemy fighter aircraft, which were described as Mitsubishi A6M Navy Type 0 (Allied reporting name, “Zeke,” but best known as the “Zero”) or Nakajima Ki-43 Army Type 1 Fighters (the Hayabusa, Allied reporting name, “Oscar”).

One of the B-24s had been badly damaged and diverted to Milne Bay. Four of the five B-17s which returned to Port Moreseby were damaged.
San Antonio Rose, the B-17 carrying General Walker, was seen trailing smoke and diving through clouds. A Fifth Air Force message stated, “Later B-17 was observed heading south just east of Vunakanau [10 miles (16 kilometers) south-southwest of Rabaul] at about 5,000 feet, left outboard engine smoking but later appeared alright, was being closely pursued by four to five Zekes and last seen going into clouds.” A Japanese fighter pilot wrote that the B-17 was seen flying to the south, about 25 miles south of Rabaul. It was not seen again.
San Antonio Rose and its crew never returned from the mission. Searches over the next several days were unsuccessful. The 11 airmen were listed as Missing in Action.³
On 12 December 1945, the crew of San Antonio Rose were reclassified as Killed in Action.

Kenneth Newton Walker was born 17 July 1898 at Los Cerrillos, a tiny community along the “Turquoise Trail” in the Territory of New Mexico. He was the son of Wallace Walker and Emma Helen Overturf Walker. His father abandoned them when he was very young. Mrs Walker took Kenneth to Denver, Colorado, and later to Kansas City, where he attended Central High School. He graduated from the Omaha High School of Commerce in Omaha, Nebraska in 1915. Ken Walker studied business through a college extension course.
The United States entered World War I on 6 April, 1917. Ten months later, 10 December 1917, Kenneth Newton Walker enlisted in the Signal Enlisted Reserve Corps, United States Army, at Denver, Colorado. Walker was 5 feet, 8 inches (1.73 meters) tall, with a high forehead and ruddy complexion. He had brown hair and green eyes.
Walker was promoted to private first class, Aviation Section, Sig. E.R.C., 7 March 1918. Pfc. Walker was then assigned to the University of California School of Military Aeronautics, and in June 1918, he began flight training at the Air Service Flying School, Mather Field, near Sacramento, California. On completion of his flight training, Pfc. Walker was discharged from his enlistment, effective 1 November 1918, to accept a commission as a second lieutenant, Aviation Section, Signal Corps, United States Army, the following day.
2nd Lieutenant Walker was sent to Brooks Field at San Antonio, Texas, where he trained as a flight instructor. He was then assigned to Barron Field, south of Fort Worth, Texas. In 1919, Walker was reassigned to Post Field at Fort Sill, Oklahoma.
Under the National Defense Act of 1920, the Aviation Section became the Air Service, a distinct combatant branch of the Army, and was no longer a part of the Signal Corps. This resulted in changes in officers’ commissions.
2nd Lieutenant Walker’s commission was vacated on 15 September 1920. Retroactively, he received a commission as a 2nd Lieutenant, Air Service, United States Army, effective 1 July 1920, and was promoted to 1st lieutenant with the same date of effect. The new commission was accepted 15 September 1920. His rank as 1st lieutenant was accepted 13 April 1921.

2nd Lieutenant Walker married Miss Marguerite Potter, 28 September 1922. The ceremony was performed by Rev. H. Leach Hoover at St. Andrew’s Church, Lawton, Nebraska. The Walkers would have two sons: Kenneth Newton Walker, Jr., born in 1927, and Douglas Potter Walker, born in 1933.
Also in 1922, Lieutenant Walker graduated from the Air Service Observation School, as a qualified aerial observer. On 15 December 1922, Walker was discharged as a 1st lieutenant, A.S., U.S.A., and appointed a 2nd lieutenant.
Lieutenant Walker was assigned to Nichols Field, south of Manila on the island of Luzon, in the Philippine Islands. He was once again promoted to 1st lieutenant, 24 July 1924.

On 18 August 1934, Lieutenant Walker married Ms. Juliet G. Wimberly in Madison County, Alabama. This was the second marriage for both. A second wedding ceremony took place in Franklin County, Tennessee, 8 September 1934, officiated by L.J. Sisk, Justice of the Peace. They would have one son, John W. Walker. This marriage ended in divorce at Reno, Nevada, in February 1940.

On 23 December 1937, Captain Walker was piloting one of three Douglas B-18 twin-engine bombers which had picked up recent graduates from the Air Corps Technical School at Rantoul, Illinois, and were returning them to Hamilton Field, Novato, California. After a stop at Denver Municipal Airport (now Stapleton International Airport, DEN), Captain Walker’s airplane was the second to takeoff. Just after becoming airborne, the B-18 crashed.
Captain Walker said,
“We were about 20 feet off the ground and going about 80 miles an hour when the ship just seemed to lose power,” he said. “I kicked hard on the left rudder and we swung around at right angles after sliding across that little gully,” indicating a ravine at the roadside.
The B-18 hit the runway, slid about 200 feet (61 meters) then cut through a fence and came to rest on a roadway between a ravine and railroad tracks. None of the nine men on board ⁴ were injured but the B-18 was seriously damaged. It had flown just 49 hours since new. (49:00 TTSN)

Attended the General Staff School from 10 March 1942 to 1 July 1942. Walker was promoted to the temporary rank of Brigadier General, Army of the United States, on 17 June 1942.
In addition to the Medal of Honor, Brigadier General Kenneth Newton Walker was awarded the Distinguished Service Cross, the Silver Star, the Legion of Merit and the Purple Heart.
General Walker’s remains have not been recovered. There is a cenotaph in his memory is at the Arlington National Cemetery, Arlington, Virginia. His name, along with the other airmen of San Antonio Rose, appears on the Walls of the Missing, Manila American Cemetery, Taguig City, Philippines. In 1948, Roswell Army Air Field was renamed Walker Air Force Base in his honor.

San Antonio Rose was a Boeing B-17F-10-BO Flying Fortress, c/n 3143, Army Air Corps serial number 41-24458. The bomber was built during the summer of 1942, in the same production block with another famous B-17, Memphis Belle (41-24485). It was delivered to the United States Army Air Corps 8 July 1942.
Deep within my heart lies a melody A song of old San Antone Where in dreams I live with a memory Beneath the stars all alone
It was there I found beside the Alamo Enchantment strange as the blue, up above A moonlit path that only she would know Still hears my broken song of love
Moon in all your splendor knows only my heart Call back my Rose, Rose of San Antone Lips so sweet and tender like petals fallin’ apart Speak once again of my love, my own
Broken song, empty words I know Still live in my heart all alone For that moonlit pass by the Alamo And Rose, my Rose of San Antone

² Postwar analysis found that one ship, the transport Keifuku Maru, 5,833 tones, had been bracketed by two bombs and sank. Another freighter, Kagu Maru, and the Minikaze-class destroyer Tachikaze, were damaged. (Tachikaze had been damaged in an earlier air attack, 27 December 1942, and its commanding officer killed.) On 5 January 1943, the destroyer was alongside Yamabiko Maru, a passenger-cargo steamer which had been converted to a repair ship for the Imperial Japanese Navy.

Amelia Mary Earhart (Harris & Ewing)Judge Clarence Elliot Craig
5 January 1939: After she had been missing for 18 months, Judge Clarence Elliot Craig of the Superior Court of the County of Los Angeles County declared Amelia Mary Earhart legally dead in absentia,¹ at the request of her husband, George Palmer Putnam II. She and navigator Fred Noonan disappeared while enroute from Lae, Territory of New Guinea, to Howland Island in the Central Pacific, 2 July 1937.
George Palmer Putnam and Amelia Earhart had met in 1928 while he was interviewing prospects for a transatlantic flight to be sponsored by Mrs. Amy Phipps Guest. She was selected to make the flight and became the first woman to fly the Atlantic Ocean, aboard Donald Woodward’s Fokker F.VIIb/3m, Friendship, which was flown by Wilmer Stutz and Louis Gordon. (See This Day in Aviation, 17–18 June 1928) They were married 7 February 1931 at his parents’ home in Noank, Connecticut.

Judge Craig appointed Mr. Putnam as the executor of Earhart’s estate, which contemporary news reports said was “estimated at more than $10,000.”
Amelia Earhart Declared Dead
Court Names Husband of Lost Aviator as Executor of Estate
Amelia Earhart, ill-fated aviator who was lost during an attempt to girdle the earth at the Equator in an airplane 17 months ago, yesterday was declared dead in a Los Angeles probate court.
Five minutes later Superior Judge Elliott craig named her husband, George Palmer Putnam, Hollywood publisher and writer, sole executor of an estate estimated at more than $10,000.
CALLED EXTRAORDINARY
Acknowledging as extraordinary the procedure of declaring a person legally dead less than seven years from the date of disappearance, Judge Craig reasoned that Miss Earhart’s death could not be classified as usual.
To bolster his petition, Putnam had presented to the court a thick file of affidavits from naval officers and Department of the Interior officials who led the search for his lost wife in the South Pacific during the first week of July, 1937.
LOG IN EVIDENCE
The log of the Navy cutter Itasca was given as evidence that a thorough search for the aviator, lost on the homeward leg of her globe flight with her navigator, Capt. Fred Noonan, had proved beyond a shadow of a doubt that she was dead.
Judge Craig set July 2, 1937, as the exact date of Miss Earhart’s demise.
Miss Earhart’s will, dated April 1, 1932, made at Rye, N.Y., named Putnam as executor. He will get all her personal property. The remainder goes into a trust fund of which the income will be sent to her mother, Mrs. Amy Otis Earhart of Medford, Mass., quarter-annually.

Less than five months later, on 21 May 1939, Mr. Putnam married Mrs. Jean-Marie Cosigny James, an author, at Boulder City, Nevada. This was Putnam’s third marriage. It would end in divorce in 1945.

4 January 1959: At approximately 16:40 UTC, the Soviet automatic space probe First Cosmic Ship came within 5,995 kilometers (3,725 miles) of the Moon. It was the first man-made craft to arrive in the vicinity of Earth’s natural satellite.
First Cosmic Ship (which was later known as Мечта (Mechta, “Dream”) and today is called Luna 1) was launched from the Scientific-Research Test Range No. 5 at Tyuratam, Kazakhstan (later named the Baikonur Cosmodrome) at 16:41:21 UTC, 2 January 1959, aboard an 8K72 three-stage launch vehicle.
Mechta was the fourth in a series of lunar probes, and was intended to impact the surface of the Moon. It was spherical with several antennas, and weighed 361 kilograms (795.9 pounds). The probe carried a magnetometer, Geiger counter, scintillation detector and micrometeorite detector. It was powered by batteries. Radio telemetry equipment relayed the data to Earth.
Luna I trajectory.
It was intended that the spacecraft would impact the lunar surface, but an error in programming the third stage burn time caused a near miss. After 34 hours of flight, the probe passed within 5,995 kilometers (3,725 miles) of the lunar surface. It then entered a solar (heliocentric) orbit between Earth and Mars, where it remains today, circling the Sun every 450.0 days.
The Vostok-L 8K72 was a modified R-7 Semyorka intercontinental ballistic missile. The R-7 rocket was designed by Sergei Pavlovich Korolev, known as The Chief Designer.
The 8K72 version consisted of two core stages with four external boosters. The first stage and each of the boosters were powered by a four-nozzle RD-107 rocket engine burning kerosene and liquid oxygen. Total thrust was approximately 1,100,775 pounds. The second stage used a RD-0105 engine, producing 11,015 pounds of thrust. The Luna 1 was propelled by a third stage which remained attached during the translunar coast phase of flight.
The first two stages were 30.84 meters (101.18 feet) high and weighed 277,000 kilograms (610,680 pounds). The Luna 1 third stage weighed 1,472 kilograms (3,245 pounds), empty. It was 5.2 meters (17.06 feet) long with a diameter of 2.4 meters (7.87 feet).
The 8K72 rocket was capable of launching a 4,000 kilogram (8,818.5 pound) payload into Low Earth Orbit. The last launch of an 8K72 was in 1960, but the current Soyuz launchers are based on this early rocket.
Luna 1 was the first space vehicle to reach escape velocity and leave Earth’s gravitational field; the first to reach the vicinity of the Moon, and the first man-made device to orbit the Sun.
Luna 1 was launched from Tyuratam at 16:41:21 UTC, 2 January 1959.
