9 September 1913 (27 August 1913, Old Style¹): At the Syretsky military airfield west of Kiev, Ukraine, Imperial Russia, Пётр Николаевич Нестеров (Pyotr Nikolayevich Nesterov), a military officer, flew a Nieuport IV.G into an inside loop, the first time this aerobatic maneuver had ever been performed.

Nesterov’s Loop

Also known as “Nesterov’s Loop,” or a “dead loop,” the inside loop was completed by entering from a dive, pulling the nose up and flying in a closed curve in the vertical plane (with the top of the airplane toward the center of the loop at all times), and then returning to a dive.

This maneuver is now performed beginning and ending in straight and level flight, but airplanes of the time had insufficient power.

The airplane flown by Lieutenant Nesterov was a Nieuport IV, designed by the French aircraft company, Société Anonyme des Éstablissements Nieuport, and built in Russia by several manufacturers. The variant flown by the Imperial Russian Air Service was powered by an air-cooled, normally-aspirated, 10.292 liter (628.048 cubic inch displacement Société des Moteurs Gnome Gamma seven-cylinder rotary engine, which produced 70 horsepower at 1,200 r.p.m.

“. . . I sat head down for a few moments and did not feel rush of blood to the head, I was sitting tightly, and legs pressed on the pedal … Tools in the open boxes remained in their places. Gasoline and oil also keeps the centrifugal force at the bottom of the tank, ie, at the top, and normally fed to the engine, which worked perfectly the entire upper half of the loop. In general, all this proves that the airplane made ​​regular rotation, only in the vertical plane, as all the time there was a dynamic equilibrium. With this only turning the air is defeated by man. . . . Man mistakenly forgot that in the air the support is everywhere, and he should cease to determine the direction in relation to the earth. “

One year later, 8 September 1914 (25 August 1914, Old Style), Nesterov became the first pilot to destroy an enemy aircraft in aerial combat. Flying a Morane Saulnier Type G near Zhovkva, Ukraine, Nesterov rammed an Albatros B.II. Both aircraft were so badly damaged that they crashed. The Austrian pilot, Franz Malina, and observer, Baron Friederich von Rosenthal, were both killed. Nesterov died of his injuries the following day.

Boeing B-52H-170-BW Stratofortress 61-0026, CZAR FIVE TWO, 2:16 p.m. PDT, 24 June 1994. (U.S. Air Force)

24 June 1994: At Fairchild Air Force Base, southwest of Spokane, Washington, a Boeing B-52H-170-BW Stratofortress, serial number 61-0026, call sign Czar Five Two, was being flown by Lieutenant Colonel Arthur Alan (“Bud”) Holland, the aircraft commander, with Lieutenant Colonel Mark C. McGeehan, commanding officer of the 325th Bomb Squadron, as the co-pilot. The vice commanding officer of the 92nd Bomb Wing, Colonel Robert E. Wolff, was aboard as the designated safety observer. The fourth crew member, Lieutenant Colonel Kenneth S. Horton, the 325th squadron operations officer, was the radar navigator.

The mission was a practice flight for an upcoming air show demonstration. During the 18 minute flight, virtually every maneuver performed by Lieutenant Colonel Holland exceeded the operating limitations of the B-52, and violated Air Force and Federal Aviation Administration regulations.¹

Bud Holland was notorious for his reckless flying. Many crew members had asked not to be assigned to fly with him. Many prior instances of dangerous flying had occurred, and officers in Holland’s chain of command was aware of these, but seemed to tolerate it.

Apparently, Holland thought that he was such a great pilot that he could make the B-52 do anything.

While approaching the runway for a touch-and-go, the control tower instructed Czar 52 to go around because of another aircraft that had just landed and was still on the runway. Holland requested to make a left 360° turn around the tower, which was approved.

At an altitude of just 250 feet (76 meters)—the B-52’s wingspan is 185 feet—Holland put the bomber into a nearly 90° left bank. As he approached the 270° point of the turn, Czar 52‘s wings went beyond the 90° point. Holland added power, but no amount of power could keep the B-52 in the air by now. The bomber simply fell out of the sky, impacting the ground with a 95° angle of bank and 150 knots (278 kilometers per hour) indicated air speed. Lieutenant Colonel McGeehan fired his ejection seat, but did not escape before impact. All four officers were killed.

The following You Tube video shows the actual crash of Czar 52. Other videos available on the internet show the entire air show practice, as well as previous examples of Holland’s dangerous flying.

The crash of Czar Five Two is an example of Command Failure. Everyone in the chain of command knew that Bud Holland was a dangerous pilot, but no one, with the exception of Lieutenant Colonel McGeehan, tried to stop him.

61-0026 was one of the last B-52 bombers built by Boeing before production ended in 1962. It was accepted by the U.S. Air Force on 2 June 1962.

The B-52H is a sub-sonic, swept wing, long-range strategic bomber. It was originally operated by a crew of six: two pilots, a navigator and a radar navigator, an electronic warfare officer, and a gunner. (The gunner was eliminated after 1991). The airplane is 159 feet, 4 inches (48.565 meters) long, with a wing span of 185 feet (56.388 meters). It is 40 feet, 8 inches (12.395 meters) high to the top of the vertical fin. The B-52H uses the vertical fin developed for the B-52G, which is 22 feet, 11 inches (6.985 meters) tall. This is 7 feet, 8 inches (2.337 meters) shorter than the fin on the XB-52–B-52F aircraft, but the fin’s chord is longer. The bomber has an empty weight of 172,740 pounds (78,354 kilograms) and its Maximum Takeoff Weight (MTOW) is 488,000 pounds (221,353 kilograms).

The most significant difference between the B-52H and the earlier Stratofortresses is the replacement of the eight Pratt & Whitney J57-series turbojet engines with eight Pratt & Whitney Turbo Wasp JT3D-2 (TF33-P-3) turbofans, which are significantly more efficient. They are quieter and don’t emit the dark smoke trails of the turbojets. The TF-33 is a two-spool axial-flow turbofan engine with 2 fan stages, a 14-stage compressor section (7-stage intermediate pressure, 7-stage high-pressure) and and a 4-stage turbine (1-stage high-pressure, 3-stage low-pressure). Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons). The TF33-P-3 is 11 feet, 10 inches (3.607 meters) long, 4 feet, 5.0 inches (1.346 meters) in diameter and weighs 3,900 pounds (1,769 kilograms).

The B-52H has a cruise speed of 525 miles per hour (845 kilometers per hour). It has a maximum speed of 632 miles per hour (1,017 kilometers per hour) at 23,800 feet (7,254 meters)—0.908 Mach. The service ceiling is 47,700 feet (14,539 meters). The unrefueled range is 8,000 miles (12,875 kilometers). With inflight refueling, its range is limited only by the endurance of its crew.

The B-52H was armed with a 20mm M61A1 Vulcan six-barreled rotary cannon in a remotely-operated tail turret. The gun had a rate of fire of 4,000 rounds per minute, and had a magazine capacity of 1,242 rounds. After 1991, the gun and its radar system were removed from the bomber fleet. The flight crew was reduced to five.

The B-52H can carry a wide variety of conventional free-fall or guided bombs, land-attack or anti-ship cruise missiles, and thermonuclear bombs or cruise missiles. These can be carried both in the internal bomb bay or on underwing pylons. The bomb load is approximately 70,000 pounds (31,751 kilograms).

At the time of the crash, 61-0026 had a total of 12,721.5 hours on its airframe. It was the only B-52 remaining at Fairchild AFB and had been meticulously maintained and inspected. There were no discrepancies related to the accident. It was valued at $73,700,000.

Arthur Alan (“Bud”) Holland was born 7 September 1947, in Suffolk, Virginia. He was the son of Arthur Leroy and Virginia Holland.

Holland attended Campbell University, Bules Creek, North Carolina, where he was a cadet in Reserve Officers Training Corps. He received a commission as a second lieutenant, United States Air Force Reserve in January 1971.

Holland and his wife, Sarah Anne, had two daughters, Heather Lee and Mary Margaret.

At the time of his death, Holland had served in the U.S. Air Force for over 23 years. He was a rated Command Pilot with a total of 5,275.3 flying hours, with 5,038.3 hours in the B-52 series (61.1 hours combat, B-52G).

Holland’s remains were interred at Fairmont Memorial Park, Spokane, Washington.

¹ In the official U.S. Air Force Aircraft Accident Investigation Board report (AFR 110-14), the list of regulations and technical orders violated by Lieutenant Colonel Holland on this 18 minute flight takes up three full pages (Page 23, 24, and 25).

25 May 1927: At Wright Field, now Wright-Patterson Air Force Base, Dayton, Ohio, First Lieutenant James H. “Jimmy” Doolittle, United States Army Air Corps, was the first pilot to successfully perform an outside loop.

Flying a Curtiss P-1B Hawk pursuit, he began the maneuver in level flight at 10,000 feet (3,048 meters), then pushed the nose down into a dive. When he reached 280 miles per hour (450 kilometers per hour), Doolittle continued to pitch the nose “down” and the airplane flew through a complete vertical circle, with the pilot’s head to the outside of the loop.

Jimmy Doolittle attempted to repeat the outside loop at the 1929 Cleveland National Air Races, with a Curtiss P-1C Hawk, serial number 29-227. The airplane’s wings came off but Doolittle parachuted to safety. (The Curtiss P-1C used wing radiators instead of the large radiator under the nose of the P-1B. This substantially reduced the aerodynamic drag which allowed the airplane to accelerate to too high an airspeed during Doolittle’s maneuver.)

Jimmy Doolittle was one of America’s foremost pioneering aviators. He set many records, won air races, tested and developed new flying equipment and techniques. He was a highly-educated military officer, having earned his Bachelor of Arts from the University of California Berkeley School of Mines, and M.S and D.Sc. degrees in Aeronautical Engineering from the Massachusetts Institute of Technology. As a pioneer aviator, he won every international air race, and had been awarded every international aviation trophy. He was also the first pilot to fly completely by reference to instruments.

During the early days of America’s involvement in World War II, Lieutenant Colonel Doolittle planned and led the Halsey-Doolittle B-25 raid on Japan. He was awarded the Medal of Honor and promoted to brigadier general. He was placed in command of the 12th Air Force in North Africa, then as a major general, the 15th Air Force in the Mediterranean Theater of Operations. Lieutenant General Doolittle commanded the 8th Air Force in England from January 1944 to September 1945. He then supervised the transition of the 8th to the Boeing B-29 Superfortress and its its eventual transfer to bases on Okinawa to continue the war against Japan. World War II came to an end, however, before any of the 8th’s B-29s actually moved west.

After the war, Lieutenant General Doolittle was placed on the inactive list. On 4 April 1985, by Act of Congress, James H. Doolittle was promoted to General.

General James Harold Doolittle is the only person to be awarded both the Medal of Honor and the Medal of Freedom. He died 27 September 1993 at the age of 96 years.

The Curtiss P-1B Hawk was a single-place, single engine biplane pursuit, an aircraft type now known as a fighter. The airplane and its D-12 Conqueror engine were both built by the Curtiss Aeroplane and Motor Co., Garden City, New York. It was 22 feet, 11 inches (6.985 meters) long with a wingspan of 31 feet, 6 inches (9.601 meters) and overall height of 8 feet, 10¾ inches (2.712 meters). It had a maximum weight of 2,841 pounds (1,288.7 kilograms).

The P-1B was powered by a water-cooled, normally-aspirated, 1,145.1-cubic-inch-displacement (18.8 liter) Curtiss V-1150-3 (D-12D) dual overhead cam (DOHC) 4-valve 60° V-12 engine with a compression ratio of 5.7:1. It was a direct-drive engine, rated at 415 horsepower at 2,000 r.p.m. at Sea Level, and 460 horsepower at 2,300 r.p.m. The D-12 was 58¾ inches (1.492 meters) long, 34¾ inches (0.883 meters) high and 28¼ inches (0.718 meters) wide. It weighed 680 pounds (308 kilograms).

The pursuit had a maximum speed of 165 miles per hour (265.5 kilometers per hour), service ceiling of 21,000 feet (6,400.8 meters) and range of 342 miles (550 kilometers).

The P-1B was armed with two machine guns, one .50-caliber and one .30-caliber.

The Air Corps ordered 93 Curtiss P-1 Hawks between 1925 and 1929.
