9 January 1793: At approximately 10:00 a.m., Jean-Pierre François Blanchard ascended from the courtyard of the Walnut Street jail in Philadelphia, Pennsylvania, aboard a hydrogen-filled silk balloon. Aboard were various scientific instruments and a small dog.

Blanchard has sold tickets for viewing the balloon launch, and many people were present, including George Washington, who provided Messr. Blanchard with a letter of introduction.

A contemporary newspaper article described the event: [Note, at the time, the English letter ſ (“long s”) was similar to the symbol for “f”.]

M. Blanchard,

     The celebrated aeronaut made his 45th voyage in a magnificent balloon, from the Priſon court of the city of Philadelphia, the 9th inſt.  amidſt the acclamations of an immenſe concourſe of ſpectators. His aſcencion was majeſtick; he ſaluted his terreſtial gazers with his flag, and appeared to be as much elated, as he was elevated. At the moment in time when THE PRESIDENT arrived, to be preſent at the inflation of the the baloon, 15 rounds were fired by Capt. Fiſher‘s artillery; two cannon were fired every quarter hour until Mr. B. aſcended, when he was ſaluted with a federal diſcharge. At the date of our accounts, he had not deſcended; and it was impoſſible for anyone to ſay in what direction his car would move; or where he would land. If the wind in the upper atmosphere was fair, he was expected to arrive at New-York at night — The citizens of which place were on the look-out for this unusual viſitant.Columbian Centinel, Boston, Saturday, 19 January 1793, Page 2, Column 4.

The “aerostat” and its passengers rose to an altitude of approximately “200 fathoms” (600 feet, 183 meters) and drifted to the southeast with the air currents. After 46 minutes of flight, Blanchard and his balloon alighted near the village of Deptford, Gloucester County, New Jersey. Though he spoke no English, Blanchard was able to have some local farmers help him return to Philadelphia. Shortly thereafter, he returned to France.

21 November 1783

21 November 1783: At approximately 2:00 p.m., Jean-François Pilâtre de Rozier and François Laurent le Vieux d’Arlandes (Monsieur le Marquis d’Arlandes) departed Château de la Muette , the home of Louis XVI and Marie-Antoinette near the Bois de Boulogne in the western outskirts of Paris, aboard a hot air balloon which had been designed and built by the brothers Joseph-Michel Montgolfier and Jacques-Étienne Montgolfier.

De Rozier had made several tethered ascents previously, learning to control the balloon. On this, the first manned, untethered ascent, de Rozier and Marquis d’Arlandes rose to an altitude of approximately 3,000 feet (910 meters) and drifted to the southwest. After about 25 minutes, they descend to land between two windmills outside the city, at Butte-aux-Cailles. They had traveled about five miles (nine kilometers). They could have flown farther, but the embers from the fire were beginning to scorch the balloon.

The Montgolfier brothers were the sons of a paper maker. They combined with Jean-Baptiste Réveillon, a wallpaper manufacturer, to construct their balloon envelopes of taffeta (a woven silk fabric) coated by an alum/varnish mixture.

The balloon flown by de Rozier and the Marquis d’Arlandes had an approximate volume of 60,000 cubic feet (1,699 cubic meters). It was approximately 75 feet (22.86 meters) tall with a diameter of 50 feet (15.24 meters). The air within the balloon was heated by burning coals. This resulted in a pressure differential: the heated air was less dense that the ambient air. This caused the balloon to rise.

Jean-François Pilâtre de Rozier was killed 15 June 1785, while attempting to cross the English Channel in a hydrogen balloon along with Pierre Romain. Adverse winds blew him back onshore, but for unknown reasons, the balloon collapsed and fell approximately 1,500 feet (457 meters) to the ground near Wimereux, Pas-de-Calais.

François Laurent le Vieux d’Arlandes died in 1806, possibly committing suicide.

4 November 1927: Captain Hawthorne C. Gray, United States Army Air Corps, a balloon pilot since 1921, has carried out a series of ascents to study the effects of very high altitude on air crews.

Gray lifted off from Scott Field, Belleville, Illinois, at 2:13 p.m., in a helium-filled balloon with an open wicker gondola suspended below. The balloon, Air Corps serial number S 30-241, was constructed of rubberized silk and coated with aluminum paint. It had a volume of 70,000 cubic feet (1,982.2 cubic meters). In the gondola were instruments for measuring altitude and temperature, as well as two sealed recording barographs provided by the National Aeronautic Association (NAA). Captain Gray was dressed in heavy leather clothing for protection against the cold. Three gas cylinders of oxygen were provided for breathing at altitude.

Early in the ascent, high winds carried him to the south, and though accompanied by four airplanes, their pilots quickly lost sight of Gray’s balloon. It disappeared into a heavy overcast 20 minutes after takeoff and rose to a peak altitude of 42,470 feet (12,944.9 meters) at 4:05 p.m.

Based on Captain Gray’s notes and data from the barographs, it was concluded that his ascent was at a much slower rate than his previous altitude flights. At 3:17 p.m., he wrote “Clock frozen.” Without the clock, Gray was unable to calculate his time aloft and the amount of breathing oxygen remaining. Estimates prior to lift off were that the supply would run out at 4:38 p.m. The balloon had only descended to 39,000 feet (11,887 meters) by 4:28 p.m. The barographs showed an increase in rate of descent at this time, indicating that Captain Gray was venting helium from the balloon to try to descend faster. The descent slowed, however, suggesting that Gray had lost consciousness.

The balloon and gondola were found near Sparta, Tennessee at 5:20 p.m., with Hawthorne Gray’s body curled in the bottom of the gondola. Captain Gray suffered a loss of oxygen which resulted in his death.

Captain Gray was awarded the Distinguished Flying Cross, posthumously, and is buried at the Arlington National Cemetery.

9–10 October 1900

9–10 October 1900: The Aéro-Club de France held a long-distance balloon race, coinciding with the World’s Fair and Olympic Games. Six balloon teams competed for the Grand Prix, including that of Henri François Joseph, Comte de la Vaulx, and Joseph Félix Georges, Comte de Castillon de Saint-Victor, co-founders, along with several others, including Jules Verne, of the Aero Club.

From the American Monthly Review of Reviews, Vol. 23, January–June 2001, beginning at Page 609 :

M. le Comte, Henri de la Vaulx, 1908. (Agence ROL)

Of the six balloons entered for this record-breaking race, the Centaur was one of the smaller, its dimensions being 1,630 cubic meters, while its chief competitor, the St. Louis, measured 3,000 cubic meters. The Centaur rose from the grounds at Vincennes at 20 minutes past 5 in the afternoon of October 9. From Count de la Vaulx’s account of the journey, which appears in Pearson’s for April, we glean the following facts:

“Our direction at the start was north-north-east, and very soon, the sun having gone down, Paris was nothing for us but a vast, vaguely defined patch of luminosity far to the west. The Centaur was in equilibrium at about 5,000 feet [1,524 meters] above the sea-level, when the moon rose with such a radiant brilliance that we could read all our instruments without the aid of the electric lamp. Every now and then a shooting star traversed the vault of heaven, inciting us to wish for the success of our enterprise. . . .”

Count de la Vaulx described the route of the flight, the cities and landmarks that they passed over, the weather and temperatures at various altitudes. At several times during the race, they were in sight of another balloon, the larger St. Louis.

Centaur ascended as high as 22,000 feet (6,706 meters) and experienced temperatures as low as -12 °C. (10 °F.) The changes in air temperature caused the gas in the balloon to expand and contract, and it rose and fell as the density of the gas varied.

Having expended their supply of breathing oxygen, the two aeronauts opened the balloon’s vents to descend closer to the ground. Their anchor rope caught in some trees and Centaur came to earth shortly thereafter.

La Vaulx and Saint-Victor had landed near Korostyshiv, Ukraine. The two counts had traveled 1,153 miles (1,856 kilometers) in 35¾ hours.

Having crossed the Russian frontier without passports, the two gentlemen were held in custody for four days before being allowed to return to France by train.

8 October 1958

8 October 1958: At Holloman Air Force Base, southeast of Alamogordo, New Mexico, the Project MANHIGH III balloon was launched at 6:51 a.m., Mountain Standard Time (13:51  UTC). The helium balloon lifted a 1,648 pound (748 kilogram) pressurized gondola. Inside was Lieutenant Clifton Moody McClure III, U.S. Air Force.

Over the next three hours, the balloon ascended to an altitude of 99,700 feet (30,389 meters)¹ over the Tularosa Basin.

From this altitude, “Demi” McClure radioed to Dr. David G. Simon, who had flown a previous MANHIGH mission, “I see the most fantastic thing, the sky that you described. It’s blacker than black, but it’s saturated with blue like you said. . . I’m looking at it, but it seems more like I’m feeling it. . . I have the feeling that I should be able to see stars in this darkness, but I can’t find them, either—I have the feeling that this black is so black it has put the stars out.”

The purpose of the MANHIGH flights was to conduct scientific research through the direct observations of the pilot while in contact with ground-based scientists and engineers, and to gather physiological data about the stresses imposed on a human body during extreme high altitude flight.

Lieutenant McClure was born at Anderson, South Carolina, 8 November 1932, the son of Clfton M. McClure, Jr., a bookkeeper (who would serve as a U.S. Marine Corps officer during World War II) and Frances Melaney Allen McClure. He attended the Anderson High School, graduating in 1950. He earned a bachelor’s degree in materials engineering and a master’s degree in ceramic engineering from Clemson University. He had been an instructor pilot, flying the Lockheed T-33A Shooting Star jet trainer, at air bases in Texas, but was then assigned to the Solar Furnace Project at Holloman AFB.

Prior high-altitude balloon flights had shown the need for extreme physiological fitness, and McClure was selected through a series of medical and physical evaluations similar to those that would later be used to select astronaut candidates for Project Mercury. He was considered to be physiologically and psychologically the best candidate for MANHIGH flights.

The MANHIGH III balloon was manufactured by Winzen Research, Inc., Minneapolis, Minnesota. It had a capacity of approximately 3,000,000 cubic feet (84,950 cubic meters) and was filled with helium.

The gondola was built of three cast aluminum cylindrical sections with hemispherical caps at each end. It was 9 feet (2.743 meters) high with a diameter of 3 feet (0.914 meters). Inside were cooling and pressurization equipment ,and equipment for various scientific experiments.

Lieutenant McClure wore a modified David Clark Company MC-3A capstan-type partial-pressure suit with an International Latex Corporation MA-2 helmet for protection. He breathed a mixture of 60% oxygen, 20% nitrogen and 20% helium.

During the flight, Lieutenant McClure became dehydrated. Later, temperatures inside the gondola rose to 118 °F. (47.8 °C.). The cooling system was unable to dissipate heat from McClure’s body, and his body core temperature rose to 108.6 °F. (42.6 °C.). After twelve hours, it was decidede to end the flight. MANHIGH III touched down a few miles from its departure point at 2342 UTC, 9 October 1958.

After his participation in Project MANHIGH, Clifton McClure applied to become an astronaut in Project Mercury. He was turned down because his height—6 feet, 1 inch (1.854 meters)— exceeded the limits imposed by the small Mercury space capsule. He was awarded the Distinguished Flying Cross for the MANHIGH III flight. He later flew Lockheed F-104 Starfighters with the South Carolina Air National Guard.

Clifton Moody McClure III died at Huntsville, Alabama, 14 January 2000, at the age of 67 years.

¹Sources vary. A NASA publication, Dressing For Altitude, cites McClure’s maximum altitude as 98,097 feet (29,900 meters) (Chapter 4, Page 162). The Albuquerque Tribune reported McClure’s altitude as 99,600 feet (30,358 meters), (Vol. 36, No. 163, Saturday, 11 October 1958, Page 7 at Column 6. The National Museum of the United States Air Force states 99,700 feet (30,389 meters). 99,700 feet is also cited in Office of Naval Research Report ACR-64, “Animals and Man in Space,” 1962.
