1 July 1912: While flying her new two-place Blériot XI monoplane, at the Third Annual Boston Aviation Meet at Squantum, Massachusetts, Harriet Quimby and her passenger, William A. P. Willard, Jr., organizer of the Meet, flew out over the water:

As the pair returned from circling the Boston Light far out in the bay, the sky had turned a dazzling orange. Five thousand spectators watched as the monoplane approached over the tidal flats, strikingly silhouetted against the blazing sky. Without any warning, the plane’s tail suddenly rose sharply, and Willard was pitched from the plane. The two-passenger Blériot was known for having balance problems, and without Willard in the rear seat, the plane became gravely destabilized.

For a moment it seemed that Quimby was regaining control of the plane. But then it canted forward sharply again, and this time Quimby herself was thrown out. The crowd watched in horror as the two plunged a thousand feet to their deaths in the harbor. Ironically, the plane righted itself and landed in the shallow water with minimal damage.

Quimby was 37 years old.

The cause of the accident is unknown and there was much speculation at the time. What is known is that neither Quimby nor Willard were wearing restraints. Also, the Blériot XI was known to be longitudinally unstable. With the nose pitched down the tail plane created more lift, which caused the nose to pitch down even further.

Massachusetts Standard Certificate of Death, Harriett Quimby.

Harriet Quimby was born 11 May 1875 at Arcadia, Michigan. She was the fourth child of William F. Quimby, a farmer, and Ursula M. Cook Quimby. The family moved to California in 1887, initially settling in Arroyo Grande, and then San Francisco. There, she worked as an actress, and then a writer for the San Francisco Call newspaper, and Leslie’s Illustrated Weekly. Quimby also wrote a number of screenplays for early Hollywood movies which were directed by D.W. Griffiths.

Harriet Quimby portrayed a fishermaiden in D.W. Griffith’s “Lines of White on a Sullen Sea,” 1911. (IMDb)

Harriet Quimby was the first American woman to become a licensed pilot. After 33 flight lessons over a four-month period at the Moisant Aviation School at Hempstead, Long Island, New York, on 1 August 1911, Harriet Quimby took her flight test and became the first woman to receive a pilot’s license, Number 37, from the Aero Club of America. She was called as “America’s First Lady of the Air.”

Miss Quimby was well-known throughout the United States and Europe, and she wore a “plum colored” satin flying suit. But she was a serious aviator. Just twelve weeks earlier, on 6 April 1912, Harriet Quimby became only the second pilot to fly across the English Channel when she flew a Blériot XI from Dover to Hardelot-Plage, Pas-de-Calais, in 1 hour, 9 minutes. Her only instruments were a hand-held compass and a watch.

Harriet Quimby was buried at the Kensico Cemetery, Valhalla, New York.

Miss Quimby’s airplane was a tandem seat variant of the Blériot XI single-seat, single-engine monoplane, designed by Raymond Saulnier and built by Louis Charles Joseph Blériot. The basic airplane was 24 feet, 11 inches (7.595 meters) long with a wingspan of 27 feet, 11 inches (8.509 meters) and overall height of 8 feet, 10 inches (2.692 meters). The wings had a chord of 6 feet (1.829 meters). The airplane had an empty weight of 507 pounds (229.9 kilograms).

In its original configuration, the airplane was powered by an air-cooled, 3.774 liter (230.273 cubic inches) R.E.P.  two-row, seven-cylinder fan engine (or “semi-radial”) which produced 30 horsepower at 1,500 r.p.m., driving a four-bladed paddle-type propeller. The R.E.P. engine weighed 54 kilograms (119 pounds). This engine was unreliable and was soon replaced by an air-cooled 3.534 liter (215.676 cubic inch) Alessandro Anzani & Co., 60° (some sources state 55°) three-cylinder “fan”-type radial engine (or W-3) and a highly-efficient Hélice Intégrale Chauvière two-bladed fixed-pitch propeller, which had a diameter of 6 feet, 8 inches (2.032 meters). The Anzani W-3 was a direct-drive, right-hand tractor engine which produced 25 horsepower at 1,400 r.p.m. It was 1.130 meters (3 feet 8.49 inches) long, 1.500 meters (4 feet, 11.01 inches) high, and 0.720 meters (2 feet, 4.35 inches) wide. The engine weighed 66 kilograms (145.5 pounds).

The Blériot XI had a maximum speed of 47 miles per hour (76 kilometers per hour) and the service ceiling was (3,280 feet) 1,000 meters.

30 June 1956: At approximately 10:32 a.m., two airliners, United Airlines’ Douglas DC-7 serial number 44288, Mainliner Vancouver, Civil Aeronautics Administration registration N6324C, and Trans World Airlines’ Lockheed L-1049-54-80 Super Constellation serial number 4016, Star of the Seine, N6902C, were over the Grand Canyon at 21,000 feet (6,400 meters).

Both airliners had departed Los Angeles International Airport shortly after 9:00 a.m. TWA Flight 2 was headed for Kansas City Municipal Airport with 64 passengers and 6 crew members. United Flight 718 was enroute to Chicago Midway Airport with 53 passengers and 5 crew members.

The airplanes were over the United States desert southwest, which, at that time, was outside of radar-controlled airspace. They were flying around towering cumulus clouds to comply with regulations that they “remain clear of clouds.”

The airplanes collided at about a 25° angle. The accident report describes the impact:

First contact involved the center fin leading edge of the Constellation and the left aileron tip of the DC-7. The lower surface of the DC-7 left wing struck the upper aft fuselage of the L-1049 with disintegrating force. The collision ripped open the fuselage of the Constellation from just forward of its tail to near the main cabin door. The empennage of the L-1049 separated almost immediately. The plane pitched down and fell to the ground. Most of the left outer wing of the DC-7 had separated and aileron control was restricted. . . .

This illustration depicts the collision. (Milford Joseph Hunter/LIFE Magazine)

The Constellation struck the ground near Temple Butte at an estimated 475 miles per hour (765 kilometers per hour). The DC-7’s left wing was so badly damaged that it went into an uncontrolled left spin and crashed at Chuar Butte. All 128 persons on the two airliners were killed.

This, as well as other accidents, resulted in significant changes in the United States air traffic control system.

Boeing B-52H-170-BW Stratofortress 61-0026, CZAR FIVE TWO, 2:16 p.m. PDT, 24 June 1994. (U.S. Air Force 120101-F-RL411-019)

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. Huston, 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. Officers in Holland’s chain of command were aware of these violations, but seemed to tolerate them. Only Lieutenant Colonel McGeehan had tried to have Holland grounded, but he was overruled.

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, 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 wings of the B-52H have a total area of 4,000 square feet (371.6 square meters). The leading edges are swept aft to 36° 58′. The angle of incidence is 6°, and there is 2° 30′ dihedral. (The wings are very flexible and exhibit pronounced anhedral when on the ground.) To limit twisting in flight, the B-52H has spoilers on top of the wings rather than ailerons at the trailing edges.

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). The TF33-P-3 has a maximum continuous power rating of 14,500 pounds of thrust (64.499 kilonewtons) at 9,750 r.p.m., N1. Military Power, limited to 30 minutes, is 16,500 pounds (73.396 kilonewtons) at 10,000 r.p.m., N1. Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons) at 10,050 r.p.m., N1, with a 5-minute limit. The TF33-P-3 is 11 feet, 4.32 inches (3.4625 meters) long, 4 feet, 4.93 inches (1.3442 meters) in diameter and weighs 3,900 pounds (1,769 kilograms).

The B-52H has a cruise speed of 456 knots (525 miles per hour/845 kilometers per hour). It has a maximum speed, with Military Power, of 555 knots (639 miles per hour/1,028 kilometers per hour) at 20,700 feet (6,309 meters)—0.906 Mach. The service ceiling is 46,900 feet (14,295 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.

Grumman F9F-5 Panther Bu. No. 125228 explodes after striking the flight deck of USS Midway (CVB-41), 23 June 1951. (U.S. Navy)

23 June 1951: Operating in the Atlantic Ocean off the Virginia Capes, the United States Navy aircraft carrier USS Midway (CVB-41) was conducting suitability trials of the Grumman F9F-5 Panther. Commander George Chamberlain Duncan, commanding Fighter Squadron 51 (VF-51), was in the cockpit of Bu. No. 125228. Having made a successful landing aboard Midway, Duncan took off to make another approach and landing.

Just short of the flight deck, the Panther dropped below the correct approach. Duncan tried to pull up, but the fighter struck the ramp and broke in half. The aircraft exploded in flames. The forward section slid down the deck. Duncan, though burned, was quickly rescued.

The Grumman F9F-5 Panther was a single-seat, single-engine turbojet powered fighter designed for operation from the U.S. Navy’s aircraft carriers. It was 38 feet, 10½ inches (11.849 meters) long, with a wingspan of 38 feet, 0 inches (11.528 meters)— not including wing tanks. Its overall height was 12 feet, 4 inches (3.759 meters). The wings could be hydraulically folded to reduce the span for storage aboard ship. The F9F-5 weighed 10,147 pounds (4,603 kilograms) empty, and had a gross weight of 17,766 pounds (8,059 kilograms). The maximum takeoff weight (MTOW) was 18,721 pounds (8,492 kilograms).

The F9F-5 was powered by a Pratt & Whitney JT7 (J48-P-6 or -6A) engine, a license-built version of the Rolls-Royce Tay. It was a single-shaft turbojet with a single-stage centrifugal-flow compressor, 9 combustion chambers and a single-stage axial-flow turbine. The J48-P-6 was rated at 6,250 pounds of thrust (27.80 kilonewtons), and 7,000 pounds (31.14 kilonewtons) with water injection.

The  F9F-5 Panther had a cruise speed 481 miles per hour (774 kilometers per hour). Its maximum speed was 604 miles per hour (972 kilometers per hour) at Sea Level. Its service ceiling was 42,800 feet (13,045 meters), and the range was 1,300 miles (2,092 kilometers).

The Panther was armed with four M3 20 mm autocannon placed in the nose. It could carry up to 3,465 pounds (1,361 kilograms) of bombs or eight 5-inch (12.7 centimeters) rockets on four hardpoints under each wing.

The XF9F-2 prototype first flew 21 November 1947. 1,382 F9F Panthers were produced and they remained in service with the U.S. Navy and Marine Corps until 1958. 619 of these were the F9F-5 variant. A swept wing version, the F9F-6 through F9F-9J Cougar, was also produced.

Captain George Chamberlain Duncan, United States Navy

George Chamberlain Duncan was born at Tacoma, Washington, 11 Feb 1917. He was the first of three children of of George W. Duncan, a mining camp supplier, and Frances Delarsh Chamberlain Duncan. Duncan attended Stadium High School in Tacoma. He played on the football and swim teams. He was also a member of the glee club, and during his senior year, portrayed “Oliver le Dain” in the comic opera, “The Vagabond King.” He was a member of the school’s glider and architecture clubs. Duncan graduated in 1934.

Midshipman George C. Duncan, U.S. Navy

George Duncan entered the United States Naval Academy, Annapolis, Maryland, as a midshipman, 18 July 1935. He graduated 1 June 1939 and was commissioned an Ensign, United States Navy. Ensign Duncan served aboard the Colorado-class battleship USS West Virginia (BB-48) from June 1939 to August 1941.

Ensign Duncan married Miss Agnes Wirt Tawresey at Washington, D.C., 30 August 1941. They would have four children, three sons, George, Jr., Richmond, Alfred, and a daughter, Agnes.

Ensign Duncan was next assigned to the Northampton-class heavy cruiser USS Louisville (CA-28), serving aboard in 1942 and 1943.

Duncan was promoted to the rank of lieutenant (junior grade), 1 June 1942. Two weeks later, 15 June 1942, he was promoted to lieutenant (temporary).

Lieutenant Duncan underwent flight training at NAS Pensacola. Following graduation he was assigned to Fighting Squadron Fifteen (VF-15) aboard USS Essex (CV-9). Duncan was promoted to lieutenant commander (temporary) 15 March 1944.

On 13 September 1944, Lieutenant Commander Duncan was engaged in aerial combat over the central Philippine Islands. He was credited with destroying an enemy medium bomber and two fighters, shared credit for a second bomber shot down, and damaged a third fighter. He followed this by strafing an airfield and destroying three aircraft on the ground. For these actions, Duncan was awarded the Silver Star.

During the Battle off Cape Engaño on the morning of 25 October 1944, Lieutenant Commander Duncan led VF-15 in an attack against Imperial Japanese Navy warships in the Sibuyan Sea. He scored a direct hit with a bomb on the light carrier IJN Chitose, which, along with a number of other hits, resulted in its sinking at 0937 hours. Duncan was awarded the Navy Cross.

Duncan is officially credited with 13½ enemy aircraft destroyed.

In March 1945, Lieutenant Commander Duncan was assigned to the Naval Postgraduate School at Annapolis, Maryland. In 1949, he graduated from the 48-week Test Pilot Division course at NATC Patuxent River. On 1 June 1949, his rank of lieutenant commander became permanent. On the same day, Duncan was promoted to commander. This was also a permanent rank.

Commander Duncan served as the commander of VF-51 aboard the Essex-class aircraft carrier USS Valley Forge (CVA-45) during the Korean War. He later commanded  VF-101, and was Commander Air Group (“CAG”), Carrier Air Group 5 (CVG-5). He was next assigned as the Head, Fighter Design Branch, Bureau of Aeronautics (BuAir), then, Assistant Director, Aircraft Division, Bureau of Weapons (BuWeps). Returning to sea, Commander Duncan was executive officer of the “supercarrier” USS Forrestal (CV-59). Duncan was promoted to the rank of captain, 1 April 1958.

For a Naval Aviator to be given command of a U.S. Navy aircraft carrier, they generally have to have had command of a “deep-draft” ship. Captain Duncan was given command of the 13,900-ton aircraft stores ship USS Jupiter (AVS-8) from July 1961 to 24 March 1962. Jupiter had a draft of 25 feet, 10 inches (7.874 meters). During this time, Jupiter operated with the 7th Fleet, and was homeported at Yokosuka, Japan.

Captain Duncan assumed command of the Forrestal-class aircraft carrier USS Ranger (CV-61), 7 May 1962, and remained in that assignment until 20 May 1963.

Captain Duncan retired from the United States Navy in December 1967. During his naval career, he had been awarded the Navy Cross, the Silver Star, the Legion of Merit, the Distinguished Flying Cross with one silver star and one gold star (seven awards), and the Bronze Star with Combat “V.”

Following his retirement, Duncan attended George Washington University, Washington, D.C., where he earned a degree in law. He was a practicing attorney in Alexandria, Virginia.

Agnes Duncan died in 1972. In 1974, Captain Duncan married Margaret Handy. She died in 1980.

Captain Duncan suffered a fatal heart attack while in a restaurant in Alexandria, Virginia, 15 December 1995, at the age of 77 years. He is buried at the Arlington National Cemetery, Arlington, Virginia, alongside his first wife.

23 June 1913: While parked at St. Petersberg, Igor Ivanovich Sikorsky’s S-21, Русский Витязь (Russky Vityaz or “Russian Knight”), the world’s first four-engine airplane, and, at the time, the world’s largest airplane, was crushed by an engine that had fallen off of a single-engine Morane-Saulnier airplane that was flying overhead.

Russky Vityaz, the Sikorsky S-21. (Bain News Service/Library of Congress LC-B2-3222-11)

Igor Sikorsky began work on the S-21 in 1911, while chief engineer for Russko-Baltiisky Vagonny Zavod at St. Petersburg, and it first flew 10 May 1913. It was a four-engine biplane operated by a crew of three and could carry up to seven passengers in two enclosed cabins. These cabins were large enough that the passengers could stand and move  around.

The S-21 was 20 meters (65.6 feet) long. The upper wing had a span of 27 meters (88.6 feet) and the lower wing, 20 meters (65.6 feet). Overall height of the airplane was 4 meters (13.1 feet). Its empty weight was 3,400 kilograms (7,496 pounds) and the gross weight was 4,000 kilograms (8,818 pounds).

Russky Vityaz was powered by four water-cooled Argus Motoren G.m.b.H. As 1 inline four-cylinder engines in a tractor configuration. These produced 100 horsepower, each, and turned two-bladed fixed-pitch propellers. The biplane had a maximum speed of 90 kilometers per hour (56 miles per hour), service ceiling of just 600 meters (1,969 feet) and range of 170 kilometers (106 miles).

Rather than try to repair the wrecked S-21, Sikorsky decided to build something even bigger: the Sikorsky S-22 Ilya Muromets.

Igor Sikorsky emigrated to the United States of America in 1919, where he designed and built large seaplanes for airline use before focusing on the development of the helicopter, beginning with the Vought-Sikorsky VS-300. His company remains in operation today and produces some of the most widely used military and commercial helicopters.
