Lieutenant Post Plunges To Death In San Diego Bay
Beachley Blames The Government

SAN DIEGO, California – February 9, 1914 – Lieutenant Henry B. Post of the First Aero Corps, considered one of the most skillful United States Army aviators, plunged to his death in San Diego Bay today, when the right wing of his hydro-aeroplane crumpled. Lieutenant Post died after establishing an American altitude record of 12,120 feet. He fell 600 feet into shallow water and was dead when Francis Wildman, another aviator, reached the spot in a flying boat.

Lieutenant Post left the North Island hangars at 8:50 o’clock this morning after having declared his intention of breaking the American altitude record for hydro-aeroplanes. Within an hour he had attained a height of 12,120 feet, the barograph showing this figure when recovered from the wreckage.

A series of wide spirals was a feature of the descent, the machine appearing to be under perfect control. When within 600 feet of the water the plane was seen to collapse, then careen. The next instant the pilot was hurled from his seat and the machine dropped like a bullet. Post fell into five feet of water, the wrecked craft disappearing from sight a few feet away.

Captain Arthur S. Cowen, head of the First Corps, said the machine which Lieutenant Post was piloting was responsible for the accident.

“The man has the natural ability of a born flyer, and it had to take the breakage of his machine to cause his death.,” said Captain Cowen.

“The death of Lieutenant Post only substantiates the charge that I made against the policy of the United State Government last November,” said Lincoln Beachley, aviator, in a telegram received here tonight.

“At that time I blamed Congress for the deaths of the Army and Navy aviators. I do not believe Government aviation would be much better off if the $2,000,000 or $3,000,000 appropriation for the supposed betterment of the flying branch of the services were made. They simply would have a little more machines with which to kill off more officers.

“Within a week that old machine will probably be patched up with a few new wires and some cloth and another aviator will be sent out in it.”

Some time ago Beachley told Secretary Garrison that Army aviators were losing their lives because the equipment supplied to them was old.

Lieutenant Post was 28 years of age. He came here June 28, 1913 from Honolulu where he was attached to the Twenty-fifth Infantry, and became a military aviator November 11. He is survived by his widow and his sister, who came here recently to visit him from their home in Babylon, New York, where his mother also resides. His brother, V. Z. Post, is a novelist. His father died two weeks ago.

The body will be sent to Washington for interment in the Arlington National Cemetery.

The death of Lieutenant Post was the fourteenth aviation fatality to occur in the United States Army and Navy service. Beside the fourteen officers killed, two civilian instructors, Al Welch and Paul Beck, lost their lives while experimenting with Army machines. The first officer killed was Lieutenant Thomas Selfridge on September 17, 1908. He was flying as a passenger with Orville Wright at Fort Myer. Lieutenant Selfridge was the first man to lose his life in an aeroplane accident.

The other officers who lost their lives were: Lieutenant G. E. M. Kelly, on May 10, 1911, at San Antonio; Lieutenant L. W. Hazelhurst, jr., on June 11, 1912, at College Point, Maryland; Lieutenant L. C. Rockwell and Corporal Frank Scott at College Point on September 28, 1912; Lieutenants Rex Chandler and Lewis H. Brereton at North Island on April 8, 1913 [Note: Brereton survived the accident and rose to the rank of lieutenant general.—TDiA]; Lieutenant Joseph D. Park on May 9, 1913 at Los Angeles; Ensign William B. Billingsley on June 30, 1913 while flying over Chesapeake Bay; Lieutenant Loren H. Call on July 8, 1913 at Texas City; Lieutenant Moss L. Love on September 4, 1913 at San Diego; Lieutenant C. Perry Rich on November 14, 1913 when he fell into Manila Bay; and Lieutenant Kelly at San Diego on November 24, 1913.

Henry Burnet Post was born at Brooklyn, New York, 15 June 1885. He was the last of seven children of Colonel Henry Albertson Van Zo Post, a Civil War veteran, engineer and railroad equipment financier, and Caroline Burnet McLean Post.

Henry Post entered the School of Applied Science at Columbia University as a member of the Class of 1906. He studied mechanical engineering. While at the University, he was a member of the Alpha Chapter of the Delta Psi (ΔΨ) fraternity, and in 1905, was president of the sophomore class. Post was also a member of the Deutscher Verien (the German club). He participated in varsity athletics, playing the position of Left End on the University football team and the Stroke of the Varsity Eight  Crew.

Henry Burnet Post married Miss Grace Woodman Phillips at St. Paul’s Methodist Episcopal Church, Manhattan, New York City, New York, 25 January 1907. (Mrs. Post later married Captain Francis Cogswell, U.S. Navy. She was a Foreign Service Officer for the United States government during World War I. During World War II, she served with the Office of Strategic Service (O.S.S.) and later, the Central Intelligence Agency (C.I.A.). She died 21 December 1971.)

On 28 January 1910, Henry Post enlisted as a private in Troop 4, Squadron A, of the New York National Guard. He served with the Guard’s 1st Aero Squadron. On 11 February 1911, Post was commissioned as a second lieutenant in the 25th Infantry Regiment, United States Army. Lieutenant Post then attended the School of Musketry at the Presidio of San Francisco in San Francisco, California. He completed the course 6 January 1912.

Lieutenant Post joined Company E, 2nd Battalion, 25th Infantry, at Schofield Barracks on the island of Oahu, Territory of Hawaii, 22 March 1912.

During 1913, Schofield Barracks suffered an epidemic of typhoid fever as a result of a “gross pollution of the water supply.” Lieutenant Post was “sick in quarters (line of duty)”and quarantined from 27 January to 12 February 1913. He then returned to duty with Company E.

On 5 July 1913, Lieutenant Post was detached from Company E to attend the Signal Corps Aviation School, San Diego, on North Island, for training as an airplane pilot.

On 18 December 1913, he flew an airplane to 10,500 feet (3,200 meters). 10 days later, 28 December 1913, Georges Lagagenaux of France set a Fédération Aéronautique Internationale (FAI) World Record for Altitude at 6,120 meters (20,079 feet).¹

Second Lieutenant Henry Burnet Post, 25th Infantry Regiment, United States Army, died in the line of duty at San Diego, California, 9 February 1914. He was buried at the Arlington National Cemetery, Arlington, Virginia. Post Field, Fort Sill, Oklahoma, (now, Henry Post Army Airfield) was named in his honor.

The airplane flown by Lieutenant Post during his record-setting flight, and subsequent fatal accident, was a Wright Model CH hydro-aeroplane, Signal Corps serial number S.C. 10. (This was the second S.C. 10. The first, also a Wright Model C, had been destroyed in a crash during acceptance trials at College Park, Maryland, 11 June 1912. Arthur L. Welsh, a Wright Flying School instructor, and 2nd Lieutenant Leighton Wilson Hazelhurst, Jr., were killed.) The U.S.  Army Signal Corps had purchased six of these airplanes. The Model C was similar to the earlier Model B, though it had dual flight controls. The wings were shorter and the rudder taller.

The Wright Model CH was 28 feet, 6 inches (8.687 meters) long, with a wingspan of 38 feet, 0 inches (11.582 meters). The upper and lower wings had 5 feet, 0 inches (1.524 meters) vertical separation. The airplane weighed 1,160 pounds (526 kilograms), including the 240 pound (109 kilogram) float.

Three-view illustration of the Wright Model C.H. Hydro-Aeroplane. (FLIGHT, No. 245 (Vol. V., No. 36), 6 September 1913, Page 979)The airplane was powered by a water-cooled, normally-aspirated, 405.891-cubic-inch-displacement (6.651 liters) Wright inline 6-cylinder overhead-valve engine which produced 50–75 horsepower between 1,400–1,560 r.p.m. The Wright “6-60” weighed 305 pounds (138 kilograms).

Two 8 foot, 6 inch (2.591 meter) diameter, two-bladed, fixed-pitch, counter-rotating propellers, driven by a chain drive and turning 525–575 r.p.m., are mounted behind the wings in pusher configuration.

The Model C had a maximum speed of 55 miles per hour (89 kilometers per hour).

All six of Signal Corps’ Wright Model C airplanes had crashed and been rebuilt at least once. The airplanes were prone to aerodynamic stall because of the pusher propeller configuration. As the pilot raised the nose, the propellers’ thrust vector accelerated the rate of pitch change. The wings stalled and the nose pitched down. There was insufficient elevator authority to bring the airplane out of the dive.

By the end of 1913, eleven Army pilots had been killed while flying Wright Brothers’ airplanes, five of them were flying the Wright Model C. Lieutenant Henry Burnet Post was the sixth pilot to die while flying the type.

Within a week of Lieutenant Post’s death, the Army grounded all pusher-type airplanes and prohibited their future use. This ended the Wright Brothers’ business with the United States Army.

15 January 1915: At San Diego, California, Lieutenant Byron Quinby Jones, Aviation Section, Signal Corps, United States Army, set a flight endurance record of 8 hours, 53 minutes, flying a Glenn L. Martin Company Martin T Army Tractor. The flight consumed 30 gallons (114 liters) of gasoline. Lieutenant Jones estimated that he had sufficient fuel remaining for another two hours in the air, but approaching darkness forced him to land.

For this and other flights at San Diego, Lieutenant Jones was awarded the Mackay Trophy.

The Mackay Army Aviation Cup was established in 1911 by Clarence Hungerford Mackay, Chairman of the Board of Directors of the Postal Telegraph and Cable Corporation. Now known as the Mackay Trophy, it is awarded yearly for “the most meritorious flight of the year” by U.S. Air Force personnel.

Lieutenant Jones was the sixth aviator to be awarded the trophy. The trophy is kept at the Smithsonian Institution National Air and Space Museum. It was appraised in the 1960s at a value of $65,000, though it was also estimated that it would cost $650,000 to duplicate it.

Byron Quinby Jones was born at Henrietta, New York, 9 April 1988. He was one of four children of Samuel Titus Jones and Sarah Minerva Quinby Jones. He attended School 24 and East High School, Rochester, New York.

Jones entered the United States Military Academy, West Point, New York, 15 June 1907, and graduated 12 June 1912 with a bachelor of science degree. He was commissioned as a second lieutenant in the 14th Cavalry Regiment, United States Army.

Lieutenant Jones volunteered for pilot training and was sent to the Signal Corps Aviation School at North Field, San Diego, California. After earning a rating as one of the earliest U.S. military pilots and serving for a year with an active squadron, Jones was promoted to the rank of first lieutenant, Aviation Section, Signal Corps, 23 November 1914. He was then sent to the Massachusetts Institute of Technology (MIT) for the very first post-graduate course in aeronautical engineering.

In addition to he endurance records, “B.Q.” Jones was also the first Army pilot to perform a loop, an intentional stall and recovery, and a “tail spin.”

During World War I, Jones rose to the temporary rank of lieutenant colonel.

Jones married Mrs. Evelyn Clark Chadwick (née Evelyn Kennerly Clark, grand daughter of William Clark, co-leader with Meriwether Lewis of the 1804–1806 Lewis and Clark Expedition), 4 June 1917.

For the next twenty-four years, Jones steadily rose in rank and was an important figure in Army aviation. Assigned to the newly established Air Service, Jones was promoted to the rank of major, 1 July 1920, and lieutenant colonel, 1 August 1935.

In 1939, because of a disagreement with senior Air Corps officers over military aviation doctrine, Lieutenant Colonel Jones requested a return to the Cavalry. He was promoted to the rank of colonel, Army of the United States, 16 November 1940, and colonel, United States Army, 1 February 1942.

Byron Jones graduated from the Army Industrial College in 1926, Command and General Staff School, 1927, and the Army War College, 1929.

Colonel Jones was a leader in forming a mechanized cavalry and combined arms service. During World War II, he served in the Guadalcanal Campaign, and the staff of General Douglas MacArthur in Australia. He then held several assignments within the continental United States. He was hospitalized for lengthy periods several  times, and finally was discharged from the Army, 31 January 1944.

Colonel Byron Quinby Jones, United States Army (Retired), died at Walter Reed Army Hospital, 30 March 1959, at the age of 70 years. His remains were interred at the Arlington National Cemetery.

The Martin T was a two-place, single-engine biplane ordered as a trainer for the Signal Corps. Three were built and given serial numbers S.C.31–33. The airplane was a tractor configuration, with an engine and propeller at the front of the fuselage, rather than behind in a pusher configuration. The Martin T also had a wheeled tricycle undercarriage. Both of these features were relatively new and would become standard.

17 September 1908

Lt. Thomas E. Selfridge (Robert B. Williams)

17 September 1908: Orville Wright brought his Wright Flyer to Fort Myer, Virginia to demonstrate it to the U.S. Army Signal Corps.  A crowd of approximately 2,500 spectators had gathered to watch the flight.

Lieutenant Thomas Etholen Selfridge, Signal Corps, United States Army, wanted to ride along with Wright and asked to go first. Lieutenant George Sweet, U.S. Navy was scheduled for the first flight, but he and Wright agreed to let Lieutenant Selfridge go. The two men aboard the Wright Flyer made four circuits of the field approximately 150 feet above the ground. The starboard propeller broke and struck the wires supporting the rudder. As the rudder rotated sideways, it caused the airplane to pitch nose down.

Orville Wright later described the accident:

“On the fourth round, everything seemingly working much better and smoother than any former flight, I started on a larger circuit with less abrupt turns. It was on the very first slow turn that the trouble began. . . A hurried glance behind revealed nothing wrong, but I decided to shut off the power and descend as soon as the machine could be faced in a direction where a landing could be made. This decision was hardly reached, in fact I suppose it was not over two or three seconds from the time the first taps were heard, until two big thumps, which gave the machine a terrible shaking, showed that something had broken. . . The machine suddenly turned to the right and I immediately shut off the power. Quick as a flash, the machine turned down in front and started straight for the ground. Our course for 50 feet was within a very few degrees of the perpendicular. Lt. Selfridge up to this time had not uttered a word, though he took a hasty glance behind when the propeller broke and turned once or twice to look into my face, evidently to see what I thought of the situation. But when the machine turned head first for the ground, he exclaimed ‘Oh! Oh!’ in an almost inaudible voice.”

The Wright Flyer struck the ground and both men were seriously injured. Thomas Selfridge suffered a fractured skull. He underwent neurosurgery but died without regaining consciousness. Orville Wright had a broken leg, several broken ribs and an injured hip. He spent seven weeks in the Army hospital.

This was the first fatal accident involving an airplane. Lieutenant Thomas Etholen Selfridge was the first person to die in an airplane accident.

Doctors attend to the unconscious Lieutenant Selfridge following the crash of the Wright Flyer at Fort Myer, Virginia, 17 September 1908. He died later that day. (Library of Congress)
