12 June 1976: The London Gazette announced that The Queen would confer the Honour of Knighthood on Group Captain Robert Steuart Bader, C.B.E., D.S.O., D.F.C., “For services to disabled people.”
Pilot Officer Douglas Bader had lost both of his legs in an airplane crash, 14 December 1931. He was medically retired from the Royal Air Force as medically unfit for service.
With World War II approaching, Bader applied to the Air Ministry for reinstatement but was initially refused. Later, after revaluation, Bader was accepted, sent to refresher flight training, and then on to a fighter squadron.
Bader quickly rose to Section Leader, Flight Commander, Squadron Leader and Wing Commander. Flying Hawker Hurricanes and Supermarine Spitfires, he shot down at least 20 enemy airplanes. He had twice been awarded the Distinguished Service Order and twice, the Distinguished Flying Cross.
On 9 March 1941, Douglas Bader was himself shot down over France. With difficulty he was able to parachute from his Spitfire, and was quickly captured. Initially held in a hospital, Bader escaped. Recaptured, he was taken to a series of prisoner of war camps, where he continued his escape attempts. Finally the Germans imprisoned him in the notorious Colditz Castle where he remained for the rest of the war. He retired from the Royal Air Force in 1946 with the rank of Group Captain.
After the war, Douglas Bader flew for the Shell Oil Company. But he also worked unceasingly to better the lives of other disabled persons. He would tell them, “Don’t listen to anyone who tells you that you can’t do this or that. That’s nonsense. Make up your mind, you’ll never use crutches or a stick, then have a go at everything. Go to school, join in all the games you can. Go anywhere you want to. But never, never let them persuade you that things are too difficult or impossible.”
For his services to the disabled, Group Captain Bader received the honor, Commander of the Most Excellent Order of the British Empire (C.B.E.). Twenty years later he was invested Knight Bachelor.
Group Captain Sir Douglas Robert Steuart Bader, CBE, DSO and Bar, DFC and Bar, FRAeS, DL, passed away 5 September 1982, at the age of 72 years.

3 June 1946: Lieutenant Henry A. Johnson, U.S. Army Air Force, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 1,000 Kilometers Without Payload flying a Lockheed P-80A-1-LO Shooting Star, serial number 44-85123, at Dayton, Ohio. The average speed was 745.08 kilometers per hour (462.97 miles per hour). The elapsed time was 1 hour, 20 minutes, 31 seconds.¹
This airplane had earlier set a transcontinental speed record when Colonel William H. Councill flew it from Daugherty Field, Long Beach, California to La Guardia Field, New York, in 4 hours, 13 minutes, 26 seconds on 26 January 1946. It would go on to win the Thompson Trophy Race J Division, 2 September 1946, when Major Gustav E. Lundquist flew it to an average speed of 515.853 miles per hour (830.185 kilometers per hour) over the 180-kilometer course.

The Lockheed P-80-1-LO was the United States’ first operational jet fighter. It was a single-seat, single engine airplane, designed by a team of engineers led by Clarence L. (“Kelly”) Johnson. The prototype XP-80A, 44-83020, nicknamed Lulu-Belle, was first flown by test pilot Tony LeVier at Muroc Army Air Field (now known as Edwards AFB) 8 January 1944.
The P-80A was 34 feet, 6 inches (10.516 meters) long with a wingspan of 38 feet, 10.5 inches (37 feet, 7.5 inches with “clipped” wing tips) (11.849 or 11.468 meters) and an overall height of 11 feet, 4 inches (3.454 meters). The wings had 1° incidence with -1° 30° twist, and 3° 50′ dihedral. The leading edges were swept aft 9° 18′ 33″. The total wing area was 237.70 square feet (22.08 square meters). The P-80A weighed 7,920 pounds empty (3,593 kilograms) and had a maximum takeoff weight of 14,000 pounds (6,350 kilograms).

Early production P-80As were powered by either an Allison J33-A-9 or a General Electric J33-GE-11 turbojet engine. The J33 was a licensed version of the Rolls-Royce Derwent. It was a single-shaft turbojet with a 1-stage centrifugal compressor section and a 1-stage axial-flow turbine. The -9 and -11 engines were rated at 3,825 pounds of thrust (17.014 kilonewtons) at 11,500 r.p.m. They were 8 feet, 6.9 inches (2.614 meters) long, 4 feet, 2.5 inches (1.283 meters) in diameter and weighed 1,775 pounds (805 kilograms).
The P-80A-1 had a maximum speed of 510 miles per hour (821 kilometers per hour) at Sea Level, 520 miles per hour (837 kilometers per hour) at 20,000 feet (6,096 meters), and 495 miles per hour (797 kilometers per hour) at 40,000 feet (12,192 meters). The service ceiling was 45,000 feet (13,716 meters).
Several hundred of the early production P-80 Shooting stars had all of their surface seams filled, and the airplanes were primed and painted. Although this process added 60 pounds (27 kilograms) to the empty weight, the decrease in drag allowed a 10 mile per hour (16 kilometers per hour) increase in top speed. The painted surface was difficult to maintain in the field and the process was discontinued.
The P-80A Shooting Star was armed with six Browning AN-M3 .50-caliber aircraft machine guns mounted in the nose, with 300 rounds of ammunition per gun.

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.
— History of Research in Space Biology and Biodynamics, Part II, Chapter 3, NASA History Office, December 1958.
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).
Illustration of Project MANHIGH gondola. (U.S. Air Force)
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.

21 May 1955: At 05:59:45 Pacific Standard Time (13:59:45 UTC) 1st Lieutenant John M. (“Jack”) Conroy, U.S. Air Force, a World War II B-17 pilot and former Prisoner of War, took off from the California Air National Guard Base at the San Fernando Valley Airport (re-named Van Nuys Airport in 1957). His airplane was a specially-prepared North American Aviation F-86A-5-NA Sabre, USAF serial number 49-1046. His Destination? Van Nuys, California—by way of Mitchel Field, Long Island, New York. His plan was to return to the ANG base in “The Valley” before sunset.

Several weeks of planning and preparation were involved in “Operation Boomerang”. Five refueling stops would be required and Air National Guard personnel across the United States would handle that. A deviation from peacetime standards would allow the Sabre to be refueled with the engine running to minimize time spent on the ground. (The F-86 was not capable of inflight refueling.) The six-year-old F-86A was polished to ensure that all rivet heads were smooth, seams in the fuselage and wing skin panels were adjusted for precise fit, then were sealed. The gun ports for the six .50-caliber Browning machine guns in the fighter’s nose were filled then covered with doped fabric and painted. This was to reduce aerodynamic drag as much as possible. The General Electric J47-GE-13 turbojet was overhauled, then tested and adjusted for maximum efficiency.
Arrangements for official timing of the West to East and Back Again speed run were paid for by North American Aviation, Inc., whose personnel also provided technical support to the Air National Guard.
Jack Conroy’s F-86A was nicknamed California Boomerang, and had a map of the United States and a boomerang painted on the fuselage. The Sabre remained in its overall natural aluminum finish but had green stripes on the fuselage, vertical fin and wings.

After takeoff, Lieutenant Conroy climbed to approximately 40,000 feet (12,192 meters) and headed to his first refueling stop at Denver, Colorado. He landed at 7:48 a.m. PST and the Sabre was refueled and off again in just 6 minutes. From Denver he continued eastward to Springfield, Illinois, arriving at 9:32 a.m. PST. Refueling there took 5 minutes. The next stop was Mitchel Field, Long Island, New York. He touched down at 11:19 a.m., PST and remained on the ground for 39 minutes.
Conroy departed Mitchel Field on the westbound leg at 11:58 a.m. PST and arrived at Lockburne Air Force Base, Ohio at 12:58 p.m., PST. This refueling stop required 7 minutes. Next on the flight plan was Tulsa, Oklahoma. The airplane landed there at 2:26 p.m. PST, and was refueled and airborne again in 6 minutes. The last refueling took place at Albuquerque, New Mexico. Lieutenant Conroy landed at 3:58 p.m., PST. After another 7 minute stopover, California Boomerang took off on the final leg of the round-trip journey, finally landing back at Van Nuys, California at 5:26:18 p.m., PST.
John Conroy’s Coast-to-Coast-to-Coast “dawn to dusk” flight covered 5,058 miles (8,140.1 kilometers). The total elapsed time was 11 hours, 26 minutes, 33 seconds. His average speed was 445 miles per hour (716.2 kilometers per hour). Weather across the country caused some delays as Jack Conroy had to make instrument approaches to three of the airports.

20 May 1967: Colonel Robin Olds, USAF, commanding officer of the 8th Tactical Fighter Wing based at Ubon Rachitani Royal Thai Air Force Base, and Weapons System Officer 1st Lieutenant Stephen B. Croker, destroyed two Vietnam People’s Air Force MiG-17 fighters with AIM-7 Sparrow radar-guided and AIM-9 Sidewinder heat-seeking air-to-air missiles while flying McDonnell F-4C-24-MC Phantom II, serial number 64-0829, named SCAT XXVII.
An official U.S. Air Force history publication describes the air battle:
Two other MiG-17s became the victims of Col. Robin Olds and his pilot, 1st. Lt. Stephen B. Croker. [Note: at this point in time, the WSOs of USAF F-4Cs were fully-rated pilots.—TDiA] These were aerial victories three and four for Olds, making him the leading MiG-killer at that time in Southeast Asia. An ace from World War II, the 8th TFW commander was battle-tested and experienced. Olds termed the events of 20 May “quite a remarkable air battle.” According to his account:
F-105s were bombing along the northeast railroad; we were in escort position, coming in from the Gulf of Tonkin. We just cleared the last of the low hills lying north of Haiphong, in an east-west direction, when about 10 or 12 MiG-17s came in low from the left and, I believe, from the right. They tried to attack the F-105s before they got to the target.

We engaged MiG-17s at approximately 15 miles short of the target. The ensuing battle was an exact replica of the dogfights in World War II.
Our flights of F-4s piled into the MiGs like a sledge hammer, and for about a minute and a half or two minutes that was the most confused, vicious dogfight I have ever been in. There were eight F-4Cs, twelve MiG-17s, and one odd flight of F-105s on their way out from the target, who flashed through the battle area.
Quite frankly, there was not only danger from the guns of the MiGs, but the ever-present danger of a collision to contend with. We went round and round that day with the battles lasting 12 to 14 minutes, which is a long time. This particular day we found that the MiGs went into a defensive battle down low, about 500 to 1,000 feet. In the middle of this circle, there were two or three MiGs circling about a hundred feet—sort of in figure-eight patterns. The MiGs were in small groups of two, three, and sometimes four in a very wide circle. Each time we went in to engage one of these groups, a group from the opposite side would go full power, pull across the circle, and be in firing position on our tails almost before we could get into firing position with our missiles. This was very distressing, to say the least.
The first MiG I lined up was in a gentle left turn, range about 7,000 feet. My pilot achieved a boresight lock-on, went full system, narrow gate, interlocks in. One of the two Sparrows fired in ripple guided true and exploded near the MiG. My pilot saw the MiG erupt in flame and go down to the left.

We attacked again, trying to break up that defensive wheel. Finally, once again, fuel considerations necessitated departure. As I left the area by myself, I saw that lone MiG still circling and so I ran out about ten miles and said that even if I ran out of fuel, he is going to know he was in a fight. I got down on the deck, about 50 feet, and headed right for him. I don’t think he saw me for quite a while. But when he did, he went mad, twisting, turning, dodging and trying to get away. I kept my speed down so I wouldn’t overrun him and I stayed behind him. I knew he was either going to hit that ridge up ahead or pop over the ridge to save himself. The minute he popped over I was going to get him with a Sidewinder.
I fired one AIM-9 which did not track and the MiG pulled up over the ridge, turned left and gave me a dead astern shot. I obtained a good growl. I fired from about 25 to 50 feet off the grass and he was clear of the ridge by only another 50 to 100 feet when the Sidewinder caught him.
The missile tracked and exploded 5 to 10 feet to the right side of the aft fuselage. The MiG spewed pieces and broke hard left and down from about 200 feet. I overshot and lost sight of him.
I was quite out of fuel and all out of missiles and pretty deep in enemy territory all by myself, so it was high time to leave. We learned quite a bit from this fight. We learned you don’t pile into these fellows with eight airplanes all at once. You are only a detriment to yourself.
