2 June 1957: At 6:23 a.m., Central Daylight Time (11:23 UTC), Captain Joseph W. Kittinger, Jr., United States Air Force, lifted off from Richard E. Fleming Field (SGS), South Saint Paul, Minnesota, in the gondola of a helium balloon designed and built by Winzen Research Inc.

At 8:04 a.m. (13:04 UTC), Captain Kittinger reached a pressure altitude of 95,000 feet (28,956 meters). This was only 400 feet (122 meters) short of the balloon’s theoretical pressure ceiling. Using U.S. Weather Bureau data, the linear altitude of the balloon was calculated to have been 97,000 feet (29,566 meters).¹

The Fédération Aéronautique Internationale (FAI) was not asked to certify this flight, so an official record was not set.

Project MANHIGH I was intended to test various equipment and human physiology in a near-space condition. Cosmic radiation was a particular concern. This was the first of many high-altitude research balloon flights that Kittinger would make.

. . .  A Winzen crew conducted the launching, as provided by the Man-High contract, in collaboration with members of the Aeromedical Field Laboratory and other units at Holloman. The 475th Air Base Squadron, Minneapolis, provided additional helicopter support. The vehicle was a two-million-cubic-foot plastic balloon, 172.6 feet in diameter, which quickly reached the planned ceiling altitude of 95,000 feet, setting a new record for manned balloons. Test specifications called for a twelve-hour flight. However, because of an oxygen leak (due to an improperly connected valve) and also certain communications difficulties, Colonel Stapp and Mr. Winzen decided that Captain Kittinger should come down after not quite two hours at altitude. The balloon pilot was not happy with the decision, replying by radio, “Come and get me.” But he did come down, and landed successfully at 1257 hours none the worse for his experience.

Kittinger landed next to a stream approximately 7 miles (11 kilometers) south-southwest of Alma, Minnesota. The total duration of his flight was 6 hours, 36 minutes. He was awarded the Distinguished Flying Cross, the first of six he would receive during his career in the Air Force.

The Project MANHIGH balloon and gondola were designed and built by Winzen Research, Inc., South St. Paul, Minnesota. The gondola was used in all three MANHIGH flights (Kittinger, June 1957; Simons, August 1957; McClure, October 1958).

The balloon was constructed of polyethelene sheet with a thickness of  2 mils (0.002 inch/0.051 millimeter). The seams were bonded using a heat-sealing technique which had been developed by Otto Winzen. When fully inflated with helium, the envelope had a volume of 2,000,000 cubic feet (56,634 cubic meters) and diameter of 172.6 feet (52.6 meters).

The gondola is 8 feet high and 3 feet in diameter (2.4 × 0.9 meters). It consisted of a cast aluminum section with 6 portholes which served as the primary load-bearing unit of the gondola. The rest of the gondola consisted of an aluminum alloy cylinder and two hemispherical end caps. The capsule was pressurized and filled with a 60-20-20 mixture of oxygen, nitrogen, and helium.

The gondola was suspended from an open 40.4 foot (12.3 meter) diameter parachute, which was, in turn, attached the gas balloon’s suspension rigging. Four explosive devices could sever the attachments and release the gondola and parachute.

The balloon, parachute and associated equipment weighed 1,012 pounds (459 kilograms). The gondola and installed equipment weighed 598 pounds (271 kilograms) and carried another 246 pounds (112 kilograms) of used lead-acid batteries as ballast. Kittinger, with his personal equipment, food and water, added 240 pounds (109 kilograms) to the payload. Finally, there was 70 pounds (32 kilograms) of equipment for experiments, cameras and film. The total weight came to 2,166 pounds (982 kilograms).

The Project MANHIGH gondola is on display at the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.

Joe Kittinger flew three combat tours during the Vietnam War for a total of 483 combat missions. On 1 March 1972, flying a McDonnell Douglas F-4D Phantom II, he shot down an enemy Mikoyan-Gurevich MiG-21. He was himself shot down on 11 May 1972. He and his Weapons System Officer, 1st Lieutenant William J. Reich, were captured and spent 11 months at the Hanoi Hilton.

Joe Kittinger holds six Fédération Aéronautique Internationale (FAI) world records for distance set with balloons. Three are still current.² In 2012, he was technical advisor for Felix Baumgartner as he set a new world record for the highest parachute jump from the Red Bull Stratos balloon and gondola. Kittinger died 9 December 2022.

Winzen Research, Inc. was formed in 1949 by Otto Christian Winzen, an aeronautical engineer, and his wife, Vera M. Habrecht Winzen. Both were immigrants from Germany. Mr. Winzen had previously worked for the gas balloon laboratory of General Mills, Inc. Mrs. Winzen had borrowed money from her parents to start the company and held a 2/3 ownership of the company. She ran the factory and trained its workers. She also had four U.S. patents related to balloon construction.

Otto Christian Winzen was born 24 October 1917, at Cologne, Nordrhein-Westfalen, Germany. He was the son of Christian Winzen and Lilly Lerche Winzen. At the age of 19, Winzen sailed from Bremen, Germany, aboard the Norddeutsche Lloyd passenger liner S.S. Europa, on 29 June 1937. He arrived at New York City, New York, United States of America, on 5 July 1937.

Winzen studied aeronautical engineering at University of Detroit Mercy, a private Roman Catholic university in Detroit, Michigan. It was the first university to offer a complete 5-year degree program in aeronautical engineering. While there, he met the world famous aeronaut, Jean Felix Picard, and his future wife, Vera Habracht.

Reportedly, during World War II, Otto Winzen was interred as an enemy alien.

Otto Winzen later married Marion Grzyll. He committed suicide 23 November 1979 (the first Mrs. Winzen’s 59th birthday).

Wera Maria Habrecht was born 23 November 1920 at Heidenheim, Germany. She was the first of two children of Max Theodore Habrecht, a commercial photographer, and Maya Widenmann Habrecht. The family emigrated to the United States in 1923, with Mr. Habrecht traveling there first. Mrs. Habrecht followed later with her children, Wera and Roland. They first sailed from Hamburg, Germany, 13 November 1923, to the British seaport of Grimsby, Lincolnshire, aboard the passenger/cargo ship S.S. Dewsbury. On 16 Novemberl  the family boarded S.S. Montlaurier at Liverpool, England, and then sailed for New York City. The Habrecht family settled in Detroit, Michigan.

With her first name “americanized,” Vera M. Habrecht attended Cass Technical High School in Detroit, Michigan, graduating in 1939. She then studied art at the Walker Art Center and the Minneapolis School of Art, both in Minneapolis, Minnesota.

Miss Habrecht was introduced to Mr. Winzer by Professor Picard. They were married 1 February 1941, in Detroit.³ They divorced in 1958.

Mrs. Winzer was herself an aeronaut. In 1957 she competed in the 30th Annual International Gas Balloon Races in Holland.

During Project MANHIGH, she met Major David G. Simons, M.D., U.S.A.F. Major Simons flew the MANHIGH II mission, 19–20 August 1957. They were married 12 June 1959. It was the second marriage for both. This marriage also ended in divorce, 5 May 1969. Dr. Simons died 5 April 2010.

On 26 May 1975, she married her third husband, Clifford Charles La Plante, at Arlington, Virginia.

While conducting pollution research Mrs. La Plante, under the name Vera M. Simons, set a Comité International d’Aérostation (the FAI Ballooning Commission, or CIA, world record for the Longest Flight for a Female Pilot, at 133 hours, 45 minutes, 1 October 1979.⁴

Vera Maria Habrecht Winzer Simons La Plante died at Austin, Texas, 31 July 2012, at the age of 91 years.

Hermes II (NASA)

29 May 1947: At 1930 hours, Mountain Daylight Time, a Hermes II two-stage, liquid-fueled rocket was launched from Launch Complex 33 at southern end of the White Sands Proving Grounds, east of Las Cruces, New Mexico.

Earlier in the day, a launch attempt failed when the first stage engine failed to produce thrust. Repairs were made and the second attempt succeeded—sort of. . .

The plan was for the rocket to arc toward the north, heading for the far end of the proving grounds. Instead, the Hermes II arced to the SOUTH.

The Range Safety Officer was prevented from sending a DESTRUCT signal when a program scientist physically restrained him. The rocket peaked at 35 nautical miles (65 kilometers), passed over Fort Bliss and El Paso, and after about five minutes of flight, hit the ground about one-half mile from the Buena Vista Airport in Ciudad Juárez, Mexico.

At impact, the rocket dug a crater 50 feet (15.2 meters) across and 24 feet (7.3 meters) deep. The explosion shook buildings in El Paso and 25 miles (40 kilometers) away in Fabens, Texas. The rocket barely missed a powder magazine where mining companies were storing dynamite and other explosives.

Fortunately, there were no injuries, and property damage was minor.

Hermes II was the world’s first multi-stage rocket. Developed from the German V-2 rocket (Vergeltungswaffen 2), it was intended to serve as a test bed for ramjet development. The upper stage had a broad wing for flight tests of a split-wing two-dimensional ducted-airfoil ramjet. (For this launch the ramjet was not operational.) The span of the fins were increased to improve stability.

The Hermes II was 51.50 feet (15.70 meters) tall. The tail fins had a span of 17.75 feet (5.41 meters), and the second stage wing span was 15.26 feet (4.65 meters). The rocket had a gross weight of 31,750 Pounds (14,400 kilograms). The liquid oxygen/alcohol-fueled engine produced 60,000 pounds of thrust (267 kilonewtons).

In 1948, the Hermes II was redesignated RTV-G-3 by the U.S. Army.

MA-7 liftoff, 12:45:16 UTC, 24 May 1962. (NASA)

24 May 1962: Lieutenant Commander Malcolm Scott Carpenter, United States Navy, NASA Astronaut, was launched aboard Mercury-Atlas 7 at 12:45:16.57 UTC (7:45:16 a.m., Eastern Daylight Time) from Launch Complex 14 at the Cape Canaveral Air Force Station, Cape Canaveral, Florida. This was the fourth manned space flight of the American space program. Carpenter was the sixth human to fly in space.

Scott Carpenter reported,

When the ignition signal was given, everything became quiet. I had expected to feel the launch vehicle shake, some machinery start, the vernier engines light off, or to hear the lox valve make some noise, but I did not. Nothing happened until main engine ignition; then I began to feel vibration. There was a little bit of shaking. Lift off was unmistakable.

According to the NASA post-flight mission report, “The performance of the launch vehicle was exceptionally good. . . .”

During the launch, Carpenter experienced a maximum of 7.8 gs acceleration. 5 minutes, 12.2 seconds after liftoff, Aurora 7 separated from the Atlas booster and entered Earth orbit, having reached a speed of 17,534 miles per hour (28,219 kilometers per hour). The orbit was elliptical, with a minimum altitude of 86.87 nautical miles (160.88 kilometers) and a maximum of 144.96 nautical miles (268.47 kilometers). Carpenter completed an orbit every 88 minutes, 32 seconds.

During the orbital phase of the mission, a pitch horizon scanner—part of the automatic flight control system—malfunctioned, causing the capsule’s attitude jets to fire to correct perceived errors in the ship’s attitude. This caused an excessive consumption of the hydrogen peroxide fuel for the reaction controls.

At T+04:30:00 (four hours, thirty minutes after launch) the Mercury capsule’s retrorockets fired to slow the capsule and begin the reentry phase of the flight. Each of the retro rockets fired at 5 second intervals and burned for 10 seconds. The capsule decelerated 550 feet per second (168 meters per second) and fell out of orbit. The PHS failed again, yawing Aurora 7 25° off track, which prevented the full thrust of the retrorockets from being directed along the correct path. Scott Carpenter had to fire the rockets manually, resulting in a 3 second delay, and this, along with the misalignment of the capsule, caused Aurora 7 to overshoot the planned splashdown point in the Atlantic ocean by approximately 250 nautical miles (288 statute miles/463 kilometers). (N. 19° 27′, W. 63° 59′)

At 10,000 feet (3,048 meters) Aurora 7‘s main parachute opened. The spacecraft “splashed down” at 17:41:21 UTC. The total duration of the flight was 4 hours, 55 minutes, 57 seconds.

Scott Carpenter was hoisted aboard a Sikorsky HSS-2 Sea King helicopter from USS Intrepid (CVS-11). Aurora 7 was recovered by the Allan M. Sumner-class destroyer, USS John R. Pierce (DD-753), 6 hours after its landing.

The flight of Scott Carpenter and Aurora 7 was a success, but Carpenter was subject to criticism for his performance during the mission.

In 1963, Carpenter was injured in a motorcycle accident and lost some mobility in his left arm. Despite two surgical procedures, it was determined that he was ineligible for spaceflight. He resigned from NASA in 1967 and retired from the U.S Navy in 1969 with the rank of Commander.

Mercury 18, named Aurora 7 by Carpenter, was built by McDonnell Aircraft Corporation, St. Louis, Missouri. Designed to carry one pilot, the Mercury space craft could be controlled in pitch, roll and yaw by thrusters. The space capsule was truncated cone with sides angled 20° from the longitudinal axis. It was 6 feet, 10 inches (2.083 meters) long and had a maximum diameter of 6 feet, 2.50 inches (1.892 meters). The total height of the spacecraft, from the tip of the aero spike to the booster adapter, was 26 feet, 1.26 inches (7.957 meters). Aurorra 7 weighed 4,244.09 pounds ( kilograms) at Launch.

The rocket, a “1-½ stage” liquid-fueled Atlas LV-3B, number 107-D, was built by the  Convair Division of General Dynamics at San Diego, California. It was developed from a U.S. Air Force SM-65 Atlas D intercontinental ballistic missile, modified for use as a “man-rated” orbital launch vehicle.

The LV-3B was 65 feet (19.812 meters) long from the base to the Mercury adapter section, and the tank section is 10 feet (3.038 meters) in diameter. The complete Mercury-Atlas orbital launch vehicle is 93 feet (28.436 meters) tall, including the escape tower. When ready for launch it weighed approximately 260,000 pounds (117,934 kilograms).

The Atlas’ three engines were built by the Rocketdyne Division of North American Aviation, Inc., at Canoga Park, California. Two Rocketdyne LR89-NA-5 engines and one LR105-NA-5 produced 341,140 pounds (1,517.466 kilonewtons) of thrust. The rocket was fueled by a highly-refined kerosene, RP-1, with liquid oxygen as the oxidizer.

Malcolm Scott Carpenter died 10 October 2013 at the age of 88. His spacecraft, Aurora 7, is on display at the Chicago Museum of Science and Industry, Lakeshore Drive, Chicago, Illinois.

22 May 1969, 21:30:43 UTC: Just over 100 hours after launch from Kennedy Space Center, Snoopy, the Lunar Module for the Apollo 10 mission came within 47,400 feet (14,447.5 meters) of the Lunar surface during a full dress rehearsal for the upcoming Apollo 11 landing. Mission Commander Thomas P. Stafford and Lunar Module Pilot Eugene A. Cernan rode Snoopy toward the surface and back, while John W. Young remained in orbit around the Moon aboard the Command and Service Module, Charlie Brown.

Thomas P. Stafford had flown two previous missions in the Gemini Program, Gemini 6 and Gemini 9. Apollo 10 was his third space flight.

John Watts Young flew six space missions: Gemini 3 and Gemini 10, Apollo 10 and Apollo 16, and Space Shuttle missions STS-1 and STS-9. He was to command STS-61J when the space shuttle fleet was grounded following the loss of Challenger. Young has flown 34 days, 19 hours, 39 seconds in space. He made 3 EVAs with a total of 20 hours, 14 minutes, 14 seconds outside his spacecraft.

Eugene A. Cernan had flown Gemini 9 with Stafford. He would later fly Apollo 17 back to the Moon. On 13 December 1972, Gene Cernan was the last man to stand on the surface of the Moon.
