Sikorsky S-64 Skycrane N325Y, s/n 64001. (John Daniel)

9 May 1962: The Sikorsky S-64 Skycrane, N325Y, prototype of a heavy-lift helicopter, made its first flight at Stratford, Connecticut. The Skycrane was a turbine-powered evolution of the piston-engined S-60. The United States Army bought six S-64s for evaluation, and then ordered 54 production aircraft, designated CH-54A Tarhe, and 35 CH-54Bs. Sikorsky produced 12 S-64E and Fs for the commercial helicopter market.

The Sikorsky CH-54A Tarhe is a large single-main-rotor/tail rotor helicopter, specifically designed to carry large external loads. In U.S. Army service, it had a crew of five: pilot, co-pilot, third pilot and two mechanics. The third pilot was in a rear-facing cockpit position and flew the helicopter while it was hovering to pick up or position an external load.

The CH-54A is 88 feet, 5.9 inches (26.972 meters) long and 25 feet, 4.7 inches (7.739 meters) high. The main rotor has six blades and turns counter-clockwise, seen from above. (The advancing blade is on the helicopter’s right side.) The main rotor has a diameter of 72 feet (21.946 meters). The main rotor blades have a chord of 1.97 feet (0.601 meters) and incorporate a twist of -13°. The tail rotor has four blades and is placed on the left side of a vertical pylon in a pusher configuration. The tail rotor turns clockwise, as seen from the helicopter’s left side. (The advancing blade is below the axis of rotation.) The diameter of the tail rotor is 16 feet (4.877 meters). The chord of the tail rotor blade is 1.28 feet (0.390 meters).

The helicopter has an empty weight of 19,120 pounds (8,673 kilograms) a design gross weight of 38,000 pounds (17,237 kilograms) and overload gross weight of 42,000 pounds (19,051 kilograms).

The CH-54A is powered by two Pratt & Whitney JFTD12A-4A (T73-P-1) turboshaft engines, each rated at 4,000 shaft horsepower at 9,000 r.p.m. (N2) maximum continuous power at Sea Level, and 4,500 shaft horsepower at 9,500 r.p.m. (N2) for takeoff, 5-minute limit, or 30 minutes, with one engine inoperative (OEI). The maximum gas generator speed (N1) is 16,700 r.p.m. The T73-P-1 is an axial-flow free-turbine turboshaft engine with a 9-stage compressor section, 8 combustion chambers and a 4-stage turbine section (2-stage gas generator and 2-stage free turbine). It is 107.0 inches (2.718 meters) long, 30.0 inches (0.762 meters) in diameter, and weighs 966 pounds (438 kilograms). The helicopter’s main transmission is limited to a maximum 6,600 horsepower.

It has a useful load of 22,880 pounds (10,342 kilograms) and can carry a payload of 20,000 pounds (9,072 kilograms) from a single point cargo hoist.

The CH-54A has a maximum cruise speed of 115 knots (132 miles per hour, 213 kilometers per hour). It’s range is 217 nautical miles (250 miles,  402 kilometers). The CH-54A has a hover ceiling in ground effect (HIGE) of 10,600 feet (3,231 meters) and its service ceiling is 13,000 feet (3,962 meters).

The United States Army has a tradition of using Native American names for its aircraft. Tarhe (pronounced tar-HAY) was a famous chief, or sachem, of the Wyandot People of North America, who lived from 1742–1818. He was very tall and the French settlers called him “The Crane.”

9 May 1944: A Martin B-26B Marauder of the 452nd Bombardment Squadron, 322 Bombardment Group, Ninth Air Force, named Mild and Bitter, landed at RAF Bury St. Edmunds, a military airfield in Suffolk, England. When its engines had stopped, it had  completed its second combat mission of the day: an attack against an enemy airfield at Évreaux-Fauville, in the Normandy region of France.

This was the one-hundredth combat mission flown by Mild and Bitter. It had flown 310 hours, 40 minutes in combat.

In those 100 missions, the airplane had never been forced to abort for mechanical reasons, it always came back with both of its engines running, never came back with its bomb load, and most importantly, of the 166 airmen who had flown aboard, none had ever been wounded or killed.

The bomber still had the two Pratt & Whitney Double Wasp engines which had been installed at the factory, having logged 449 hour, 30 minutes, total time since new (TTSN).

The flight crew for the Marauder’s final mission was Captain Paul Shannon, aircraft commander; First Lieutenant Lee W. Rice, co-pilot; Second Lieutenant Harry R. Harp, bombardier/navigator; Staff Sergeant James K. Brandemihl, flight engineer and top turret gunner; Staff Sergeant Walter J. Bond, radio operator; and Sergeant Robert E. Johnson, tail gunner.

Following this last mission. 41-31819 was returned to the United States as part of a War Bonds tour. Following that, the B-26 was

“. . . taken to Patterson Field for study. inspection, and possible salvage.”

     Just before dark, the sleek, fast B-26 Marauder circled her English air base and slipped in to a smooth landing. Technical Sergeant William L. Stuart, a taciturn, red-haired Texan, heaved an eloquent sigh, rubbed his grease-stained hands together, got out his tools and prepared to go to work.

     The ship rolling up to his dispersal station, the “Mild & Bitter,” had just made history: she was back from her 100th combat mission. Sergeant Stuart, her crew chief, had sweated out every one of the 100 for her; now he would check her over and get her ready for Mission 101. “Mild & Bitter” thus joined the select company of famed warplanes of World War II—planes like the embattled Fortresses “Memphis Belle” and “Hell’s Angels,” and the R.A.F.’s Lancaster “S for Sugar.”

Quiet Type

     But “Mild & Bitter” had no record of hair-raising escapes. Her saga was one of good luck and almost monotonous efficiency. She had lugged 166 different airmen to battle; 26 were decorated, but not one got a Purple Heart. During her robust career she acquired some 50 flak holes, but never any damage that Bill Stuart and his ground crew could not repair overnight.

     On her first combat flight, last July 28, she led a sweep over Abbeville; the 100th mission was to bomb an airfield at Evreux, near Paris. In between she had taken the targets as they came; power plants, E-boat pens, air bases, all around France up to Holland and back. She still had her original Pratt & Whitney, 2000 Hp engines. No one had picked any soft spots for the ship, even when she neared her record. Her last two missions were done between dawn and sunset, her last four in 36 hours.

Successful Type

     Ninth Air Force men were proud of “Mild & Bitter,” proud also that her performance so well underlined the striking success in the European Theater of the whole B-26 Marauder type. Once regarded by many airmen as a hot and dangerous aircraft, the B-26 has proved to be the outstanding medium bomber of the European air war. Its combat losses (less than 0.3%) are the lowest in the theater.

     Crew Chief Stuart (who named the plane after hearing Englishmen ordering their pints of mild & bitter in a local pub) tried hard to think of something spectacular that had happened to the ship. On one raid, it is true, a burst of flak fountained up right through the open bomb bay. Hot steel fragments rattled against cold steel bombs with a hellish din. But nothing happened.

     The record of the B-26 is equally good in all other theaters of operations.

Mild and Bitter was a Martin B-26B-25-MA Marauder twin-engine medium bomber, U.S. Army Air Forces serial number 41-31819. It had been built by the Glenn L. Martin Company at Middle River, Maryland, in 1943. It was 58 feet, 2 inches (17.729 meters) long, with a wingspan of 71 feet, 0 inches (21.641 meters), and overall height of 21 feet, 6 inches (6.553 meters). The wings had a total area of 664.1 square feet (61.7 square meters). Their angle of incidence was 3° 30′ and they had 1° 17′ dihedral. The stabilizer had a span of 28 feet, 0 inches (8.534 meters), with -5° incidence and 8° dihedral. The bomber had an empty weight of 24,000 pounds (10,886 kilograms) and gross weight of 37,000 pounds (16,783 kilograms).

The B-26B-25-MA was powered by two air-cooled, supercharged, 2,804.461-cubic-inch-displacement (45.956 liter), Pratt & Whitney Double Wasp 2SB-G (R-2800-41) two-row, 18-cylinder radial engines with a compression ratio of 6.65:1. The R-2800-41 had a Normal Power rating of 1,600 horsepower at 2,400 r.p.m. to 5,700 feet (1,737 meters), and 1,450 horsepower at 2,400 r.p.m. at 13,000 feet (3,962 meters). Its Takeoff Power rating was 2,000 horsepower at 2,700 r.p.m. The Military Power rating was the same as Takeoff Power up to 2,700 feet (823 meters), and 1,600 horsepower at 2,700 r.p.m. to 13,500 feet (4,115 meters). They turned 13 foot, 6 inch (4.115 meter) diameter four-bladed Curtiss Electric constant-speed, full-feathering propellers through a 2:1 gear reduction. The R-2800-41 was 6 feet, 3.72 inches (1.923 meters) long, 4 feet, 4.50 inches (1.334 meters) in diameter, and weighed 2,300 pounds (1,043 kilograms).

The B-26B had a maximum speed of 270 miles per hour (435 kilometers per hour) at Sea Level, and 282 miles per hour (454 kilometers per hour) at 15,000 feet (4,572 meters). The airplane’s service ceiling was 21,700 feet (6,614 meters). It’s maximum ferry range was 2,850 miles (4,587 kilometers).

The B-26B was armed with 11 air-cooled Browning AN-M2 .50-caliber machine guns. One was at the nose on a flexible mount, two fixed guns were on each side of the nose in “blister packs,” there were two flexible guns in the waist. A Martin 250CE power-operated dorsal gun turret had two, as did the Bell Type M-6 hydraulically-operated gun mount in the tail.

A maximum of four 2,000 pound (907 kilograms) bombs could be carried in the bomb bay.

When the B-26 entered service, it quickly gained a reputation as a dangerous airplane and was called “the widowmaker.” The airplane had relatively short wings with a small area for its size. This required that landing approaches be flown at much higher speeds than was normal practice. With one engine out, airspeed was even more critical. Some changes were made, such as a slight increase on wingspan and the size of the vertical fin and rudder, and an emphasis was made on airspeed control during training. The Marauder had the lowest rate of combat losses of any American bomber.

The Glenn L. Martin Co. produced 5,288 Marauders between 1941–1945. It served in the Pacific, Mediterranean and European combat areas. When it was removed from service at the end of World War II, the “B-26” designation was reassigned to the Douglas A-26 Invader, a twin-engine light bomber.

9 May 1932

Captain Albert Francis Hegenberger, Air Corps, United States Army. (NASM)

9 May 1932: At McCook Field, Ohio, Captain Albert Francis Hegenberger, Air Corps, United States Army, flew the very first solo instrument approach and landing, using a system which he had developed. The Hegenberger system, which was adopted by both civil and military aviation authorities, used a series of non-directional radio beacons (NDB) and marker beacons on the ground, along with a radio-compass and other gyroscopic instruments and radio receivers aboard the aircraft, a Consolidated NY-2 biplane.

Hegenberger had located one NDB 1,500 feet (457 meters) from the airfield boundary, and another at 1½ miles (2.4 kilometers). They were aligned with the runway centerline. Both had marker beacons which would signal that the airplane was directly overhead. The radio compass aboard the airplane would indicate the direction of the NDB relative to the airplane and lights would illuminate when it passed over the marker beacons. When the airplane was heading directly toward the NDB, the needle pointed to zero.

Captain Hegenberger turned toward the inner NDB from a distance of 50 miles (80 kilometers). He passed over it at a pre-planned altitude. When the lights on the instrument panel came on indicating that he was directly over the inner marker beacon, he turned toward the outer NDB. Crossing the outer marker, Hegenberger made a 180° turn back toward the inner NDB and began his descent. As he passed over the inner NDB again, he reduced engine power and placed the airplane in a landing attitude and waited for it to touch down on the runway.

This flight was the first solo blind instrument flight, approach and landing. (Lt. James H. Doolittle had made a blind instrument flight in 1929, but he carried a safety pilot aboard.) For his accomplishment, Captain Hegenberger was awarded an oak leaf cluster (a second award) for his Distinguished Flying Cross, and received the Collier Trophy, an annual award for the greatest achievement in aeronautics in America.

Captain Albert F. Hegenberger, Air Corps, United States Army, was presented the Collier Trophy by President Franklin D. Roosevelt, 22 July 1935.

Within one week, the Civil Aeronautics Board created a new pilot rating and required that all commercial pilots demonstrate proficiency in instrument flight. In 1935, the CAB adopted Hegenberger’s system and ordered equipment installed at all major airports between New York and Los Angeles.

Albert Francis Hegenberger was born 30 September 1895 at Boston, Massachusetts, United States of America. He was the second of five children of Alphonse Frederick Hegenberger, a clerk and immigrant from Bavaria, and Emma Amanda Buegler Hegenberger, of Switzerland.

In 1913 Hegenberger entered the Massachusetts Institute of Technology (M.I.T.), Cambridge, Massachusetts, as a student of aeronautical engineering.

Following the United States’ entry into World War I, Albert F. Hegenberger enlisted as a private in the Aviation Section, Signal Corps, United States Army, 14 September 1917. He was assigned to the School of Military Aeronautics at M.I.T., graduating in December 1917. After flight training at Ellington Field, Houston, Texas, Hegenberger was commissioned a second lieutenant, Aviation Section, Signal Officers Reserve Corps, 6 April 1918. This commission was vacated 19 September 1920, and he was appointed a second lieutenant, Air Service, retroactive to 20 July 1920. He was promoted to the rank of first lieutenant, effective that  that same date.

In October 1918, Second Lieutenant Hegenberger returned to M.I.T., and entered the School of Aeronautical Engineering. He graduated in February 1919.

Lieutenant Hegenberger married Miss Louise B. Berchtold in 1919. They would have two sons, Albert F., Jr., born in 1920, and Robert F., born in 1924.

In October 1923, 1st Lieutenant Hegenberger was assigned to the 72nd Bombardment Squadron, 5th Composite Squadron, at Luke Field on the Island of Oahu, Territory of Hawaii. The squadron was equipped with the DH-4 and the twin-engine Martin NBS-1 bomber. In March 1925, Lieutenant Hegenberger was transferred to the 23rd Bombardment Squadron, 5th Composite Group.

Lieutenant Hegenberger was next assigned as chief of the Equipment Branch, Material Division, at McCook Field, Dayton Ohio. He served in that position from October 1926 until June 1927, when became chief of the Instrument and Navigation Unit.

At 7:09 a.m., Pacific Daylight Time, 28 June 1927, 1st Lieutenant Lester J. Maitland and 1st Lieutenant Albert F. Hegenberger, Air Service, United States Army, took off from Oakland Municipal Airport, California, aboard an Atlantic-Fokker C-2, serial  number A.S. 26-202, Bird of Paradise. Their destination was Wheeler Field, Honolulu, Territory of Hawaii, 2,407 miles (3,874 kilometers) across the Pacific Ocean.

1st Lieutenant Hegenberger continued in his technical assignments at McCook and Wright Fields. On 3 January 1932, he was promoted to the rank of captain.

Mrs. Hegenberger died 7 August 1933.

In August 1935, Captain Hegenberger was assigned to the 30th Bombardment  Squadron at Rockwell Field, San Diego, California. The squadron moved to March Field, near Riverside, California, and transitioned to the Martin B-10. Captain Hegenberger was advanced to the rank of major (temporary), 2 October 1935.

On 22 July 1937, Major Hegenberger married Ms. Jewel Lilly Van Houten (née Jewel Lilly Baker) at Detroit, Michigan.

From August 1937 to June 1939, Major Hegenberger was assigned to the Air Corps Tactical School, Maxwell Field, Montgomery, Alabama. Upon graduation, he was assigned to the 5th Bombardment Group at Hickam Field, Honolulu, Territory of Hawaii. The 5th was equipped with Keystone B-3 and B-4 bombers.

Major Hegenberger was appointed operations officer of the 18th Wing at Hickam, and then in November 1940, became assistant chief of staff for operations of the Hawaiian Air Force, headquartered at Fort Shafter, near Honolulu. Hegenberger was promoted to lieutenant colonel (temporary), on 30 December 1940. This rank became permanent 18 December 1941.

In April 1941, Lieutenant Colonel Hegenberger took command of the 11th Bombardment Group. The group was equipped with Douglas B-18 Bolo, but began receiving Boeing B-17 Flying Fortresses the following month.

Hegenberger was promoted to colonel (temporary), 5 January 1942. He took command of 18th Bombardment Group and Seventh Bomber Command. He was appointed Colonel, Army of the United States (A.U.S.), 8 June 1942. Returning to the continental United States, Colonel Hegenberger became assistant chief of staff for operations, Second Air Force, and commanding officer, II Bomber Command, at Fort George Wright, Spokane, Washington. In October 1942, Colonel Hegenberger took command of the 21st Bombardment Wing, based at Smoky Hill Army Air Field, Salina, Kansas, and later, Topeka Army Air Field, Topeka, Kansas.

Colonel Hegenberger was promoted to the rank of brigadier general, A.U.S., 18 September 1943. In January 1944, he was appointed Chief of Staff, Second Air Force, at Colorado Springs Army Air Field, Colorado Springs, Colorado.

The following year, January 1945, Brigadier General Hegenberger became Chief of Staff, Fourteenth Air Force, based at Chunking, China.

Their aircraft was a Fokker F.VIIa/3m three-engine, high-wing monoplane, construction number 600. The airplane was It was purchased for the Byrd Arctic Expedition by Edsel Ford, and named Josephine Ford in honor of his 3-year-old daughter, Josephine Clay Ford.

With Chief Bennett as the expedition’s pilot and Lieutenant Commander Byrd navigating, they flew approximately 840 miles (1,350 kilometers) to the Pole and returned the same day. The total duration of the flight was 15 hours, 44 minutes.

For this accomplishment, Lieutenant Commander Byrd was promoted to Commander, and Chief Bennett to Warrant Officer. Both aviators were awarded the Medal of Honor by President Coolidge.

In the years since this event, there has been speculation that the airplane may not have actually reached the North Pole. Professor Gerald Newsom of Ohio State University, an astronomer who taught celestial navigation, analyzed Byrd’s handwritten notes and estimated that because of the inadequacies of the equipment then available to Byrd, Josephine Ford may have flown 21 miles (33.8 kilometers) beyond the North Pole, or fallen 78 miles (125.5 kilometers) short. Professor Newsom pointed out, though, that the fact the Byrd was able to return to Svalbard after nearly 16 hours proves that he knew how to navigate using that equipment under those conditions.

Josephine Ford is the first Fokker F.VIIa/3m monoplane, c/n 600. It was built by Anton H.G. Fokker’s N.V. Koninklijke Nederlandse Vliegtuigenfabriek Fokker at Veere, Netherlands in 1925, and made its first flight at Schipol, 4 September 1925. It was demonstrated for Koninklijke Luchtvaart Maatschappij N.V. (KLM, Royal Dutch Airlines), then disassembled and shipped to the United States. 600 was flown from New York to Detroit, where it participated in the First Annual Aerial Reliability Tour, 28 September–3 October 1925, flown by Egbert P. Lott. The airplane was evaluated by the U.S. Army Air Corps at Wright Field, and was then sold to Edsel Ford.

The United States did not register aircraft prior to 1927. According to the Federal Aviation Administration’s Registry data base, FOKKER VII (TRI-MOTOR) Serial Number 600 was registered 21 June 1927 to the Ford Motor Company, Dearborn, Michigan, as NC267. The registration was cancelled 14 March 1930.

Fokker F.VII 3m Josephine Ford (Fokker Aircraft)

Sources vary as to the actual dimensions of the Fokker F.VIIa/3m. The Henry Ford, the museum which owns the airplane, gives its dimensions as 49.167 feet (14.986 meters) in length, with a wingspan of 63.5 feet (19.355 meters) and height of 12.75 feet (3.886 meters). Another source says that the airplane is 47 feet, 11 inches (14.605 meters) long with a wingspan of 63 feet, 4 inches (19.304 meters) and height of 12 feet, 8 inches (3.861 meters). Its empty weight is variously given as 4,630 pounds, 5,060 pounds or 6,724 pounds and maximum takeoff weight is 7,950 pounds, 8,800 pounds or 11,464 pounds. It has a cruise speed of 81 knots. Or 90. . . .

Josephine Ford was powered by three air-cooled 787¼-cubic-inch-displacement (12.901 liter) Wright Aeronautical Corporation Model J-4 Whirlwind nine-cylinder radial engines, rated at 215 horsepower at 1,800 r.p.m. The J-4 weighed 475 pounds. (The specific variant, J-4, J-4A, or J-4B, is not known.)

Josephine Ford is in the collection of The Henry Ford Museum, Dearborn, Michigan.
