16 February 1967: At Ottobrun, Germany, test pilot Wilfried von Engelhardt made the first flight of the Bölkow-Entwicklungen KG Bo-105 prototype V-2, D-HECA, a twin-engine, rigid rotor helicopter. Baron von Engelhardt took off at 5:04 p.m. The flight lasted 20 minutes. D-HECA was the second prototype. The first one was destroyed by ground resonance during pre-flight testing.
Messerschmitt AG merged with Bölkow-Entwicklungen KG in June 1968, becoming Messerschmitt-Bölkow. The following year, the new company merged with Blohm & Voss to become Messerschmitt-Bölkow-Blohm KG, or MBB. The Bo-105 A entered production in 1970. A number of civil and military variants followed.
The Bo-105 is a 5-place light helicopter powered by two turboshaft engines. It has a four-bladed rigid (or hingeless) main rotor. This gives it a high degree of maneuverability, and it is capable of performing aerobatic maneuvers. The two-bladed tail rotor is mounted high on a pylon and gives exceptional ground clearance for a helicopter of this size. There are two “clam shell” doors located at the rear of the cabin section, giving access to a large flat floor. The helicopter has been widely used by military, law enforcement and as an air ambulance.

The Bo-105 is 11,86 meters (38 feet, 10.9 inches ) long with rotors turning. The fuselage is 8,81 meters (28 feet, 10.9 inches) long, with a maximum width of 1,58 meters (5 feet, 2.2 inches). The helicopter’s overall height is 3.00 meters (9 feet, 10 inches). The helicopter has an empty weight of approximately 1,276 kilograms (2,813 pounds), depending on installed equipment, and maximum takeoff weight of 2,100–2,500 kilograms (5,512 pounds), depending on variant.
The diameter of the main rotor is 9,84 meters (32 feet, 3.4 inches). The main rotor follows the American practice of turning counter-clockwise as seen from above. (The advancing blade is on the right.) It operates at 416–433 r.p.m. (361–467 r.p.m. in autorotation). The tail rotor diameter is 1,90 meters (6 feet, 2.8 inches). It turns clockwise as seen from the helicopter’s left side. (The advancing blade is below the axis of rotation.)

The prototype was powered by two Allison 250-C18 turboshaft engines, with increasingly more powerful 250-C20, -C20B and C-28C engines being added through the production run. The Allison 250-C18 is a 2-spool, reverse-flow, gas turbine engine with a 6-stage axial-flow, 1-stage centrifugal-flow, compressor section, and a 4-stage axial-flow turbine (2-stage gas producer, and 2-stage power turbine). The 250-C18 is rated at 317 shaft horsepower at 51,600 r.p.m., N1 (6,000 r.p.m. N2).
The helicopter’s cruise speed is 127 miles per hour (204 kilometers per hour) and maximum speed (VNE) is 135 knots (155 miles per hour/250 kilometers per hour) at Sea Level. The service ceiling is 17,000 feet (5,180 meters). The Bo-105 C has a maximum fuel capacity of 580.0 liters (153.22 U.S. gallons), of which 570.0 liters (150.58 U.S. gallons) are usable. The range is 691 miles (1,112 kilometers.
The original Type Certificate for the Bölkow Bo-105 A was issued 13 October 1970. Since then, the Bo-105 series has been produced in Germany, Canada, Spain, Indonesia and the Philippines. More than 1,500 were built.

Wilhelm Friedrich Franz Eugen Baron von Engelhardt was born at Schloss Liebenberg, north of Berlin, Germany, 11 September 1928. He was the son of the Rudolf Robert Baron von Engelhardt and Ingeborg Maria Alexandrine Mathilde Baroness Engelhardt (Gräfin zu Eulenburg), and the grandson of Friedrich-Wend Fürst zu Eulenburg-Hertefeld, Count of Sandels.
Wilhelm von Engelhardt had an early interest in aviation. His stepfather, Generalmajor Carl-August von Schoenebeck, a World War I ace, commanded the Luftwaffe flight test agency at Flugplatz Rechlin-Lärz, Rechlin, Germany. Von Englehardt was able to meet a number of well known German pilots, some of whom were guests at the family home. At the age of 16, he began flight training in gliders.
With the approach of the Soviet Red Army, von Engelhardt and his family fled to Austria. (General Shoenebeck was held as a prisoner of war until 1948.) He trained in hotel management in Salzburg. Following his release from Allied custody, General Schoenebeck formed Luftfahrt-Technik, a distributor for several aircraft manufacturers, including Hiller Helicopters.
With the assistance of General Schoenebeck, in the early 1950s von Engelhardt went to Paris, France, to train as a helicopter mechanic. He next became a helicopter pilot, then flight instructor, in 1958. He flew the Hiller 12, the Bell 47, and the gas turbine-powered Sud-Ouest Djinn. Von Engelhardt flew the SNCASE SE.3130 Alouette II in Papua New Guinea, 1961–1962, then returned to France where he trained as a test pilot at École du personnel navigant d’essais et de réception (EPNER) at Istres.
Von Engelhardt was recommended as test pilot for the Bölkow-Entwicklungen KG Bo-46, by the helicopter’s rotor system designer, Hans Derschmidt. The Bo-46 was an experimental high-speed helicopter. Von Engelhardt made the first liftoff of the prototype aircraft 14 February 1964.

Wilhelm von Engelhardt served as Bölkow’s chief test pilot, from 1962 to 1973. He then became the company’s sales director and director of customer service training.
With the Soviet occupation of eastern Germany, the village where Baron von Engelhardt was born was seized. It later came under the jurisdiction of the German Democratic Republic. Following the reunification of East and West Germany, the government of the Federal Republic of Germany held control of Schloss Liebenberg.
Schloss Liebenberg is now a hotel. (Michelin)
In 1996, without informing the local population, the Federal Office for Special Tasks Related to Unification, government’s privatization agency, placed the entire village, including the castle, the 13th century church, all the homes, farm buildings and stable, for sale. The asking price was so high that it was impossible for the villagers to come up with enough money to buy their home town. There was considerable outcry from the villagers, who said that they felt as if they, too, had been put on sale.
Baron von Engelhardt, who was living in a rented coach house on the estate that his family had owned for more than 300 years, gained international recognition for his attempts to negotiate a reasonable outcome.
With his wife, Evamaria, he edited and published Brücke über den Strom, (“Bridge over the Stream”), the letters of his cousin, Sigwart Botho Philipp August zu Eulenburg, Count of Eulenburg, a musical composer who was killed during World War I.
Wilhelm Friedrich Franz Eugen Baron von Engelhardt died 24 January 2015, at the age of 86 years.

The S-51 was a commercial version of the Sikorsky R-5 series military helicopters. It was a four-place, single engine helicopter, operated by one pilot. The cabin was built of aluminum with Plexiglas windows. The fuselage was built of plastic-impregnated plywood, and the tail boom was wood monocoque construction.
The main rotor consisted of three fully-articulated blades built of metal spars and plywood ribs and covered with two layers of fabric. (All metal blades soon became available.) The three bladed semi-articulated tail rotor was built of laminated wood. The main rotor turned counter-clockwise, as seen from above. (The advancing blade is on the helicopter’s right.) The tail rotor was mounted on the helicopter’s left side in a pusher configuration. It turned clockwise as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.)

The helicopter was powered by a 986.749-cubic-inch-displacement (16.170 liter) air-cooled, supercharged, Pratt & Whitney Wasp Jr. T1B4 (R-985 AN-5) direct-drive, nine-cylinder radial engine which was placed vertically in the fuselage behind the crew compartment. This engine had a compression ratio of 6:1 and was rated at 450 horsepower at 2,300 r.p.m., Standard Day at Sea Level. The R-985 AN-5 was 48.00 inches (1.219 meters) long, 46.25 inches (1.175 meters) in diameter and weighed 684 pounds (310.3 kilograms) with a magnesium crankcase.
The S-51 had a maximum speed (VNE) of 107 knots (123.1 miles per hour/198.2 kilometers per hour). Range was 275 miles (442.6 kilometers). The service ceiling was 14,800 feet (4,511 meters). The absolute hover ceiling was 3,000 feet (914.4 meters).
Of 220 helicopters in the S-51 series built by Sikorsky, 55 were commercial models. Westland built another 159 helicopters under license.

Дмитро Дмитрович Вінер (Dimitry Dimitrovich Viner) was born in Kiev, Ukraine, Imperial Russia, 2 October 1908. He was the son of Dimitry Nicholas Weiner and Helen Ivan Sikorsky Weiner, a teacher, and the sister of Igor Ivanovich Sikorsky.
At the age of 15 years, Viner, along with his mother and younger sister, Galina, sailed from Libau, Latvia, aboard the Baltic-American Line passenger steamer S.S. Latvia, arriving at New York City, 23 February 1923.
“Jimmy” Viner quickly went to work for the Sikorsky Aero Engineering Company, founded by his uncle, Igor Sikorsky.
Dimitry Viner became a naturalized United States citizen on 27 March 1931.
Viner married Miss Irene Regina Burnett. They had a son, Nicholas A. Viner.
On 29 November 1945, Jimmy Viner and Captain Jackson E. Beighle, U.S. Army, flew a Sikorsky YR-5A to rescue two seamen from an oil barge which was breaking up in a storm off of Fairfield, Connecticut. This was the first time that a hoist had been used in an actual rescue at sea.

In 1947, Viner became the first pilot to log more than 1,000 flight hours in helicopters.
Dimitry Dimitry Viner died at Stratford, Connecticut, 14 June 1998, at the age of 89 years.
Brigadier General Charles E. Yeager, United States Air Force
Brigadier General Charles Elwood Yeager, United States Air Force, was born at Myra, Lincoln County, West Virginia, 13 February 1923. He was the second of five children of Albert Halley Yeager, a gas field driller, and Susan Florence Sizemore Yeager. He attended Hamlin High School, at Hamlin, West Virginia, graduating in 1940.
Chuck Yeager enlisted as a private, Air Corps, United States Army, 12 September 1941, at Fort Thomas, Newport, Kentucky. He was 5 feet, 8 inches tall (1.73 meters) and weighed 133 pounds (60 kilograms), with brown hair and blue eyes. He was assigned service number 15067845. Initially an aircraft mechanic, he soon applied for flight training. Private Yeager was accepted into the “flying sergeant” program.

Sergeant Yeager completed flight training at Yuma, Arizona, and on 10 March 1943, he was given a warrant as a Flight Officer, Air Corps, Army of the United States.
Assigned to the 363rd Fighter Squadron at Tonopah, Nevada, Flight Officer Yeager completed advanced training as a fighter pilot in the Bell P-39 Airacobra.
On 23 October 1943, while practicing tactics against a formation of Consolidated B-24 Liberator bombers, the engine of Yeager’s P-39 exploded. He wrote,
I was indicating about 400 mph when there was a roaring explosion in the back. Fire came out from under my seat and the airplane flew apart in different directions. I jettisoned the door and stuck my head out, and the prop wash seemed to stretch my neck three feet. I jumped for it. When the chute opened, I was knocked unconscious. . . I was moaning and groaning in a damned hospital bed. My back was fractured and it hurt like hell.

Flight Officer Charles E. (“Chuck”) Yeager, Air Corps, Army of the United States.
When the 363rd deployed to England in November 1943, he transitioned to the North American Aviation P-51B Mustang. He named his P-51B-5-NA, 43-6762, Glamourus Glen, after his girlfriend. The airplane carried the squadron identification markings B6 Y on its fuselage. On 4 March 1944, he shot down an enemy Messerschmitt Bf-109G.
On his eighth combat mission, the following day, Yeager was himself shot down east of Bourdeaux, France, by Focke-Wulf Fw 190A 4 flown by Unteroffizier Irmfried Klotz.
. . . The world exploded and I ducked to protect my face with my hands, and when I looked a second later, my engine was on fire, and there was a gaping hole in my wingtip. The airplane began to spin. It happened so fast, there was no time to panic. I knew I was going down; I was barely able to unfasten my safety belt and crawl over the seat before my burning P-51 began to snap and roll, heading for the ground. I just fell out of the cockpit when the plane turned upside down—my canopy was shot away.

Yeager was slightly wounded. His Mustang was destroyed. Over the next few months he evaded enemy soldiers and escaped through France and Spain, returning to England in May 1944. He returned to combat with a new P-51D-5-NA Mustang, 44-13897, which he named Glamorous Glenn II.¹ He later flew Glamorous Glen III, P-51D-15-NA Mustang, 44-14888.²

During World War II, Captain Yeager had been awarded the Silver Star with one oak leaf cluster (two awards); Distinguished Flying Cross; Bronze Star Medal with “V” (for valor); Air Medal with 6 oak leaf clusters (7 awards); and the Purple Heart.
With the end of the War in Europe approaching, Yeager was rotated back to the United States.
Captain Yeager married Miss Glennis Faye Dickhouse of Oroville, California, 26 February 1945, at at the Yeager family home in Hamlin, West Virginia. The double-ring ceremony was presided over by Rev. Mr. W. A. DeBar of the Trinity Methodist Church. “The pretty brunette was attired in a light aqua crepe dress of street length. Her accessories were black and her corsage was fashioned of yellow rosebuds.”
On 10 February 1947, Captain Yeager received a commission as a second lieutenant, Air Corps, United States Army, with date of rank retroactive to 6 July 1944 (the date of his A.U.S. commission). He was promoted to first lieutenant on 6 July 1947. (These were permanent Regular Army ranks. Yeager continued to serve in the temporary rank of captain.) When the United States Air Force was established as a separate military service, 18 September 1947, Yeager became an Air Force officer.
Captain Chuck Yeager, U.S. Air Force
Captain Yeager was assigned to the six-month test pilot school at Wright Field, Dayton, Ohio. He took part in several test projects, including the Lockheed P-80 Shooting Star and Republic P-84 Thunderjet. He also evaluated the German and Japanese fighter aircraft brought back to the United States after the war. Captain Yeager was then selected by Colonel Albert Boyd to fly the experimental Bell XS-1 rocket plane at Muroc Field in the high desert of southern California.

After a series of gliding and powered flights, on 14 October 1947, Captain Yeager and the XS-1 were dropped from a modified B-29 Superfortress at an altitude of 20,000 feet (6,048 meters). (Yeager had named his new rocket plane Glamorous Glennis.) Starting the 4-chambered Reaction Motors rocket engine, Yeager accelerated to Mach 1.06 at 42,000 feet. He had “broken” the Sound Barrier.
Yeager made more than 40 flights in the X-1 over the next two years, exceeding 1,000 miles per hour (1,610 kilometers per hour) and 70,000 feet (21,336 meters). He was awarded the Mackay and Collier Trophies in 1948. In 1949, the Fédération Aéronautique Internationale awarded its Gold Medal to Captain Yeager. General Yeager’s gold medal is in the collection of the Smithsonian Institution National Air and Space Museum, along with the Bell X-1 rocket plane, Glamorous Glennis.
The X-1 was followed by the Bell X-1A. On 12 December 1953, Major Yeager flew the new rocket plane to 1,650 miles per hour (2,655 kilometers per hour), Mach 2.44, at 74,700 feet (22,769 meters).
After the rocket engine was shut down, the X-1A tumbled out of control—”divergent in three axes” in test pilot speak—and fell out of the sky. It dropped nearly 50,000 feet (15,240 meters) in 70 seconds. Yeager was exposed to accelerations of +8 to -1.5 g’s. The motion was so violent that Yeager cracked the rocket plane’s canopy with his flight helmet.
Yeager was finally able to recover by 30,000 feet (9,144 meters) and landed safely at Edwards Air Force Base.
Yeager later remarked that if the X-1A had an ejection seat he would have used it.
Bell Aircraft Corporation engineers had warned Yeager not to exceed Mach 2.3.

The Aerospace Research Pilots School trained all of the U.S. military’s astronaut candidates. One of the training aircraft was the Aerospace Trainer (AST), a highly-modifies Lockheed NF-104A Starfighter. The AST was equipped with a rocket engine and a reaction control system to provide pitch, roll and yaw control when at very high altitudes where the normal aircraft flight controls could not function.

On 10 December 1963, Colonel Yeager was flying an AST, 56-762, on a zoom climb profile, aimingg for an altitude record at approximately 120,000 feet ( meters). He reached only 108,000 feet (32,918 meters) however. On reentry, the AST’s pitch angle was incorrect and its engine would not restart. The airplane went into a spin.
Yeager rode the out-of-control airplane down 80,000 feet (24,384 meters) before ejecting.
The data recorder would later indicate that the airplane made fourteen flat spins from 104,000 until impact on the desert floor. I stayed with it through thirteen of those spins before I punched out. I hated losing an expensive airplane, but I couldn’t think of anything else to do. . . I went ahead and punched out. . . .

Brigadier General Yeager made his final flight as an active duty Air Force pilot in a McDonnell Douglas F-4E Phantom II at Edward Air Force Base, 28 February 1975. During his career, General Yeager flew 180 different aircraft types and accumulated 10,131.6 flight hours. He retired the following day, 1 March 1975, after 12,222 days of service.
Chuck Yeager’s popularity skyrocketed following the publication of Tom Wolfe’s book, The Right Stuff, in 1979, and the release of The Ladd Company’s movie which was based on it. (Yeager had a “cameo” appearance in the film.) He became a spokesperson for AC Delco and the Northrop Corporation’s F-20 Tigershark lightweight fighter prototype. In 1986 and 1988, he drove the pace car at the Indianapolis 500. Yeager co-wrote an autobiography, Yeager, with Leo Janos, published in 1985, and followed in 1988 with Press On!, co-authored by Charles Leerhsen.
In 1986, President Ronald Reagan appointed General Yeager to the Rogers Commission investigating the Challenger Disaster.
