12 January 1961: Major Henry J. Deutschendorf, United States Air Force, 43rd Bomb Wing, Strategic Air Command, flew from Carswell Air Force Base, Texas, to Edwards Air Force Base, California, with a Convair B-58A-10-CF Hustler, serial number 59-2442, named  Untouchable.

There, he flew two laps of a 1,000 kilometer circuit between Edwards and Yuma, establishing six new Fédération Aéronautique Internationale (FAI) speed records at an average of 1,708.82 kilometers per hour (1,061.81 miles per hour).

Major Deutschendorf and his crew, Captain Raymond R. Wagener, Defensive Systems Officer, and Captain William L. Polhemus, Radar Navigator/Bombardier, were each awarded the Distinguished Flying Cross.

(Major Deutschendorf was the father of Henry J. Deutschendorf, Jr., who was better known by his stage name, “John Denver.”)

Untouchable, the record-setting Mach 2+ strategic bomber, was sent to The Boneyard at Davis-Monthan AFB, Tucson, Arizona, in 1969. 59-2442 was scrapped in 1977.

The Convair B-58 Hustler was a high-altitude, Mach 2+ strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator located in individual cockpits. The aircraft has a delta-winged configuration similar to Convair’s F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors.

The Hustler is 96 feet, 10 inches (29.515 meters) long, with a wing span of 56 feet, 10 inches (17.323 meters) and overall height of 31 feet 5 inches (9.576 meters). The wings’ leading edge is swept back at a 60° angle and the fuselage incorporates the “area rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder. There are no flaps.

The B-58A was powered by four General Electric J79-GE-5 axial-flow afterburning turbojet engines, suspended under the wings from pylons. This was a single-shaft engine with a 17-stage compressor and 3-stage turbine, rated at 10,300 pounds of thrust (45.82 kilonewtons), and 15,600 pounds (69.39 kilonewtons) with afterburner. The J79-GE-5 was 16 feet, 10.2 inches (5.136 meters) long and 3 feet, 2.0 inches (0.965 meters) in diameter.

The bomber had a cruise speed of 610 miles per hour (981.7 kilometers per hour) and a maximum speed of 1,325 miles per hour (2,132.4 kilometers per hour). The service ceiling is 64,800 feet (19,751 meters). Unrefueled range is 4,400 miles (7,081 kilometers). Maximum weight is 168,000 pounds (76,203.5 kilograms).

The B-58 weapons load was a combination of W-39,  B43 or B61 nuclear bombs. The large weapons could be carried in a jettisonable centerline pod, which also carried fuel, and the smaller bombs could be carried on hardpoints. There was a defensive 20 mm M61 rotary cannon mounted in the tail with 1,200 rounds of ammunition. The gun was controlled remotely by the Defensive Systems Officer.

The B-52H is a sub-sonic, swept wing, long-range strategic bomber. It has a crew of five. The airplane is 159 feet, 4 inches (48.6 meters) long, with a wing span of 185 feet (56.4 meters). It is 40 feet, 8 inches (12.4 meters) high to the top of the vertical fin. Maximum Takeoff Weight (MTOW) is 488,000 pounds (221,353 kilograms).

There are eight Pratt & Whitney TF33-PW-3 turbofan engines mounted in two-engine pods suspended under the wings on four pylons. Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons). The TF-33 is a two-spool axial-flow turbofan engine with 2 fan stages, 14-stage compressor stages (7 stage intermediate pressure, 7 stage high-pressure) and and 4-stage turbine (1 stage high-pressure, 3-stage low-pressure). The engine is 11 feet, 10 inches (3.607 meters) long, 4 feet, 5.0 inches (1.346 meters) in diameter and weighs 3,900 pounds (15,377 kilograms).

The B-52H can carry approximately 70,000 pounds (31,750 kilograms) of ordnance, including free-fall bombs, precision-guided bombs, thermonuclear bombs and cruise missiles, naval mines and anti-ship missiles.

The bomber’s cruise speed is 520 miles per hour (837 kilometers per hour) and its maximum speed is 650 miles per hour (1,046 kilometers per hour) at 23,800 feet (7,254 meters) at a combat weight of 306,350 pounds. Its service ceiling is 47,700 feet (14,539 meters) at the same combat weight. The unrefueled range is 8,000 miles (12,875 kilometers).

With inflight refueling, the Stratofortress’s range is limited only by the endurance of its five-man crew.

The B-52H is the only version still in service. 102 were built and as of 27 September 2016, 76 are still in service. Beginning in 2013, the Air Force began a fleet-wide technological upgrade for the B-52H, including a digital avionics and communications system, as well as an internal weapons bay upgrade. The bomber is expected to remain in service until 2040.

The record-setting B-52, 60-0040, named The Black Widow, had been on a 7-hour training flight with an eight-man crew, 5–6 December 1988. They were practicing “touch and go” landings and takeoffs at K.I. Sawyer Air Force Base, near Marquette, Michigan.

After the third landing, the bomber just became airborne, when at 0115 EST,

“. . . At about 75 ft airborne the #30 fuel boost pump overheated due to lack of fuel to cool it down, and, because, the spark arrester was missing from the shaft of the boost pump allowing sparks into the empty tank. The fumes then combusted and exploded inflight causing the tail section to separate from the fuselage. We went crashing to the ground over the runway. Upon hitting the ground the wing section separated from the cockpit. Both went skidding down the runway and came to rest just 3400 ft from impact. The cockpit was blocking the alert ramp for the tankers. All 8 crewmembers survived, each with varying degrees of injury. The Pilot, copilot and IP sustained the more serious injuries, while the rest of us had multiple broken bones and burns but nothing terribly serious.”

— Captain Anthony D. Phillips, Radar Navigator.

Colonel Clyde P. Evely retired from the Air Force after thirty years service. He died 7 April 2010 at 88 years of age.

30 December 1968: At the Sikorsky Aircraft Corporation plant at Stratford, Connecticut, Chief Warrant Officer 4 James Paul Ervin, Jr., United States Army, set two Fédération Aéronautique Internationale (FAI) World Records for Time to Altitude while flying a Sikorsky CH-54A Tarhe. The helicopter’s co-pilot for this flight was CW4 William T. Lamb. The “Sky Crane” reached 3,000 meters (9,842.52 feet) in 1 minute, 38.2 seconds, and 9,000 meters (29,527.56 feet) in 7 minutes, 54 seconds.¹ (It climbed through 6,000 meters (19,686 feet) in 2 minutes, 58.9 seconds.²)

Several attempts to break the existing time to altitude records had been made on 29 and 30 December. Erwin decided to deviate from Sikorsky’s recommended climb profile and, instead, climbed vertically until reaching 20,000 feet, and then returned to Sikorsky’s profile.

On the same date, CW4 Lamb, with Erwin as co-pilot, established a World Record for Altitude in Horizontal Flight, of 9,596 meters (31,483 feet).³

According to an article in U.S. Army Aviation Digest, during the record attempt flights, the regional air traffic control center called a commercial airliner which was cruising at 17,000 feet,

“. . . be advised there’s a helicopter at your 9 o’clock position descending out of 27,000 feet at a rate of 4,000 feet per minute.”

The airliner replied, “Good lord, you mean they’re up here now?”

Another pilot on the frequency asked, “What kind of helicopter is that?”

Mr. Ervin was awarded the Distinguished Flying Cross for his achievement.

A third U.S. Army aviator involved in the record attempts was Major James H. Goodloe, as was a Sikorsky test pilot, John J. Dixon.

FAI record-setting Sikorsky CH-54A Tarhe (FAI)

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 U.S. Army ordered 54 CH-54A and 35 CH-54B Tarhes. Sikorsky produced another 12 civil-certified S-64E and S-64F Skycranes. Army CH-54s were retired from service in 1995. Sikorsky sold the type certificate to Erickson Air-Crane, Inc., Medford, Oregon. Erickson operates a fleet of Skycranes for heavy lift, logging and fire fighting, and also produces parts and new helicopters for worldwide customers.

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.”

James Paul Ervin, Jr., was born 2 October 1931, in Arkansas. He was the second child of James Paul Erwin and Ruth Booker Ervin. He joined the United States Army in 1948. In 1955, he married his wife, Theresa M. (“Terry”) Ervin. They resided in Columbus, Georgia.

CW4 Ervin was considered a pioneer of Army Aviation. He was one of the first pilots to experiment with armed helicopters, and he served with the first transportation company to be equipped with the Sikorsky CH-34 Choctaw and CH-37 Mohave helicopters. During the Vietnam War, he was assigned to the 478th Aviation Company (Heavy Helicopter). Mr. Ervin retired from the United States Army in July 1969 after 21 years of service.

At 1735, 2 September 1969, as a civilian pilot working for ERA Helicopters in Alaska, Ervin was flying a Sikorsky S-64E Skycrane, N6964E, on the North Slope near Prudhoe Bay, when the helicopter broke up in flight and crashed near a drilling site, Southeast Eileen. Chief Erwin and two others aboard, Byron Davis and Allen Bryan, were killed.

The National Transportation Safety Board determined that a tail rotor pitch control link failed due to a fatigue fracture. The NTSB accident report also cited improper factory installation as a factor.

At the time of the accident, Erwin had a total of 4,787 flight hours with 830 hours in type. He was 37 years old. James Paul Erwin, Jr., is buried at the Marietta National Cemetery, Marietta, Georgia.

29 December 1949: Jackie Cochran (Lieutenant Colonel, United States Air Force Reserve) flew her North American Aviation P-51C Mustang, Thunderbird, CAA registration N5528N, to two Fédération Aéronautique Internationale (FAI) Class C-1 world speed records of 703.38 kilometers per hour (437.06 miles per hour)¹ and a U.S. National record of 703.275 kilometers per hour (436.995 miles per hour) over the 500 kilometer (310.7 mile) Desert Center–Mt. Wilson course in the Colorado Desert of southern California.

She would later be awarded the first of three Distinguished Flying Crosses for this series of flight records.

Thunderbird was Jackie Cochran’s third P-51 Mustang. She had purchased it from Academy Award-winning actor and World War II B-24 wing commander James M. Stewart just ten days earlier, 19 December 1949.

According to Civil Aviation Administration records, the airplane had been “assembled from components of other aircraft of the same type.” It has no U.S. Army Air Corps serial number or North American Aviation manufacturer’s serial number. The C.A.A. designated it as a P-51C and assigned 2925 as its serial number. It was certificated in the Experimental category and registered N5528N.

Thunderbird had won the 1949 Bendix Trophy Race with pilot Joe De Bona, after he had dropped out of the 1948 race. Its engine had been upgraded from a Packard V-1650-3 Merlin to a V-1650-7 for the 1949 race.

Jackie Cochran set three world speed records with Thunderbird. In 1953, she sold it back to Jimmy Stewart. After changing ownership twice more, the P-51 crashed near Scott’s Bluff, Nebraska, 22 June 1955 and was totally destroyed. Pilot James M. Cook parachuted with minor injuries.

The P-51B and P-51C Mustangs are virtually identical. The P-51Bs were built by North American Aviation, Inc., at Inglewood, California, while P-51Cs were built at North American’s Dallas, Texas, plant. They were 32 feet, 2.97 inches (9.829 meters) long, with a wingspan of 37 feet, 0.31-inch (11.282 meters) and overall height of 13 feet, 8 inches (4.167 meters) high. The fighter had an empty weight of 6,985 pounds (3,168 kilograms) and a maximum gross weight of 11,800 pounds (5,352 kilograms).

P-51Bs and Cs were powered by a liquid-cooled, supercharged, 1,649-cubic-inch-displacement (27.04-liter) Packard V-1650-3 or -7 Merlin single overhead cam (SOHC) 60° V-12 engine which produced 1,380 horsepower at Sea Level, turning 3,000 r.p.m and 60 inches of manifold pressure (V-1650-3) or 1,490 horsepower at Sea Level, turning at 3,000 r.p.m. with 61 inches of manifold pressure (V-1650-7). These were license-built versions of the Rolls-Royce Merlin 63 and 66. The engine drove a four-bladed Hamilton-Standard Hydromatic constant speed propeller with a diameter of 11 feet, 2 inches (3.404 meters).

The P-51B/C had a cruise speed of 362 miles per hour (583 kilometers per hour) and the maximum speed was 439 miles per hour (707 kilometers per hour) at 25,000 feet (7,620 meters). The service ceiling was 41,900 feet (12,771 meters). With internal fuel, the combat range was 755 miles (1,215 kilometers).

In military service, armament consisted of four Browning AN/M2 .50-caliber machine guns, mounted two in each wing, with 350 rounds per gun for the inboard guns and 280 rounds per gun for the outboard.

1,988 P-51B Mustangs were built at North American’s Inglewood, California plant and another 1,750 P-51Cs were produced at Dallas, Texas. This was nearly 23% of the total P-51 production.

According to the Smithsonian Institution National Air and Space Museum, “At the time of her death in 1980, Jacqueline Cochran held more speed, altitude, and distance records than any other male or female pilot in aviation history.”

Identical to the Inglewood, California-built North American Aviation P-51B Mustang, this is a Dallas, Texas-built P-51C-1-NT, 42-103023. (North American Aviation, Inc.)

At Istres, in the south of France, French World War I fighter ace and test pilot Raymond Delmotte flew a Caudron C.460 Rafale single-engine monoplane over a 3-kilometer (1.864 miles) straight course at an average speed of 505.85 kilometers per hour (314.32 miles per hour), setting a new Fédération Aéronautique Internationale (FAI) world record speed for land planes.¹

Flight reported the event:

“. . . The attempt consisted of four trial flights over a regulation three-kilometre straight course, the average time made during all of them being taken as the final result. Delmotte made a preliminary attempt in the morning, but, owing to a crosswind of 10 m.p.h. then prevailing, he was able to attain only 478 km./hr. as the average result. He then waited until the afternoon, when, the wind having fallen to about 2½ m.p.h., he took off again and accomplished an average speed of 505.84 km./hr., according to the official timers, who will submit this figure to the F.A.I. for homologation.”

The New York Daily News reported that Delmotte won a prize of 300,000 francs, equivalent to $19,000 U.S. dollars.

The Caudron C.460 Rafale was designed by Marcel Riffard, technical director of Société des Avions Caudron, a French aircraft manufacturer which had been established in 1909. (Rafale means gust: “a brief, strong, rush of wind.”) It was a light-weight, single-seat, single-engine racer with retractable landing gear. Three were built.

The airplane was primarily constructed of spruce, covered with doped fabric, with the engine cowling and fuel tanks fabricated of magnesium. It was 7.125 meters (23 feet, 4½ inches) long with a wingspan of 6.75 meters (22 feet, 1¾ inches) and overall height of 1.8 meters (5 feet, 11 inches). The C.460’s empty weight was 520 kilograms (1,146 pounds) and it had a gross weight of 875 kilograms (1,929 pounds).

The C.460s were originally powered by an air-cooled, supercharged, 7.947-liter-displacement (484.928 cubic inches) Renault 6Q inverted 6-cylinder inline overhead valve (OHV) engine. It had 2 valves per cylinder and a compression ratio of 6:1.  The engine produced 310 horsepower at 3,000 r.p.m., and 325 horsepower at 3,200 r.p.m. The direct-drive, left-hand tractor engine turned a two-bladed metal Helices Ratier automatic variable-pitch propeller with a diameter of 1.80 meters (5 feet, 10.9 inches). The Renault 6Q was 1.62 meters (5 feet, 3.8 inches) long, 0.93 meters (3 feet, 0.6 inches) high and 0.52 meters (1 foot, 8.5 inches) wide. It weighed 190 kilograms (419 pounds).

Prior to Delmotte’s speed record attempt, the C.460’s engine was changed to a larger, more powerful  9.501 liter (579.736 cubic inches) Renault 6Q engine, also a direct-drive engine, which produced 370 chaval vapeur (364.9 horsepower) at 3,250 r.p.m. The engine’s centrifugal supercharger turned 26,000 r.p.m. The variable-pitch Ratier propeller was retained.

There is little biographical information available about Raymond Delmotte. He was born at Saint-Quentin, Aisne, France, 11 November 1894. He married Mlle Louisa Dagneaux, and they had three children, Fernande, Raymond, and Ann Marie. He held ten FAI records for speed and distance. He died 13 December 1962.

The Rue Raymond Delmotte in Saint-Quentin is named in his honor.
