Jerrie Cobb was considered America’s first female astronaut candidate.

By all metrics, there was no doubt that Jerrie Cobb had the right stuff, that luminous combination of talent, experience, bravery and composure that distinguishes an astronaut from an earthbound pilot.

But she never got the chance to step inside a space capsule and hurtle into orbit. She died March 18 at 88 in Florida.

A decorated pilot, Ms. Cobb set world records for speed, distance and altitude and was the first woman to fly in the vaunted Paris Air Show. In 1959, the National Pilots Association named her Pilot of the Year, and she drew the attention of William Randolph Lovelace II, an aerospace medicine scientist who had helped select the Mercury Seven.

“Before any human being had gone into space, he was already thinking about huge orbiting space stations — Disney television-show-style things, with dozens of people aboard doing scientific research and reconnaissance,” Weitekamp said in a phone interview.

Sights on space

In Lovelace’s view, women were to function as an essential part of such space stations, working as secretaries or nurses. To determine whether they would be able to survive in space, he invited Ms. Cobb, then 28, to perform the same tests he had used on the Mercury astronaut candidates.

Undergoing the same battery of tests as NASA’s original Mercury Seven astronauts, she sat in an Albuquerque lab in early 1960 as cold water was shot into her ears to induce vertigo. Then she swallowed three feet of rubber hose for a stomach exam and downed a pint of radioactive fluid so scientists could study her metabolism.

Ms. Cobb spent a record-setting nine hours inside an isolation chamber, a dark and silent tank of water heated to match her body temperature. And for 45 minutes, she piloted a machine known as the gimbal rig, a gyroscopic, vomit-inducing spaceflight simulator that spun her on three axes at once.

The tests were conducted privately and not officially approved by NASA. But when it was announced in August that she had passed all the tests used to qualify the Mercury Seven for space flight, she was widely considered the leading contender to become America’s first female astronaut.

After Lovelace announced in a Stockholm news conference that Ms. Cobb had aced the testing program, scoring in the top 2 percent of pilots and bettering many of her male colleagues, public interest in a female astronaut program began to grow.

Ms. Cobb helped Lovelace and his collaborator, Air Force Brig. Gen. Don Flickinger, select additional pilots for their Woman in Space Program, poring over flight records to identify promising female aviators. With support and funding from Jacqueline Cochran, the first woman to break the sound barrier, 19 female pilots took the tests.

In addition to Ms. Cobb, twelve more passed with “no medical reservations,” forming a cohort that Ms. Cobb described as the First Lady Astronaut Trainees, or FLATs. But the program was disbanded in late summer 1961, after a Navy aviation school in Pensacola, Fla., barred Lovelace from using its spaceflight testing facilities without official permission from NASA.

Dubbed an “astronautrix” and “astronette” by publications such as Life magazine, which noted the size of her bust alongside the breadth of her aviation résumé, she lobbied for NASA to launch women into space, testifying at a 1962 congressional hearing and meeting with Vice President Lyndon B. Johnson.

But Ms. Cobb’s efforts, and those of a dozen other women who were later nicknamed the Mercury 13, were spurned by NASA and dismissed by male peers including John Glenn.

So Ms. Cobb, a trailblazing female pilot who had spent much of her life battling those who said no woman was fit to fly, decamped to the Amazon, where for more than five decades she flew humanitarian missions to remote tribes.

Delivering seeds, foods, medicine and clothing, she was deep in the jungle on July 20, 1969, when she learned by radio that Neil Armstrong and Buzz Aldrin had landed on the moon. Ms. Cobb celebrated by dancing in the moonlight on her grounded plane, prancing from one wing tip to the other.

“Yes, I wish I were on the moon with my fellow pilots, exploring another celestial body,” she wrote in a 1997 autobiography, “Jerrie Cobb, Solo Pilot.” “How I would love to see our beautiful blue planet Earth floating in the blackness of space. And see the stars and galaxies in their true brilliance, without the filter of our atmosphere. But I’m happy flying here in Amazonas, serving my brethren. Contenta, Señor, contenta. (I am happy, Lord, happy).”

Advocacy for more female astronauts

Ms. Cobb became the country’s most prominent supporter of female astronauts, seeking to overturn a NASA provision that required all astronaut candidates to have experience flying military jets — an opportunity that was closed to women.

Working with Jane B. Hart, a fellow FLAT and the wife of Sen. Philip Hart (D-Mich.), she attended a House subcommittee hearing, where she testified that female pilots were “not trying to join a battle of the sexes.”

"We seek, only, a place in our nation’s space future without discrimination,” she said, two years before the Civil Rights Act of 1964 outlawed sex discrimination.

Ms. Cobb’s testimony was followed by that of astronauts such as Glenn, who had recently become the first American to orbit the Earth. “The men go off and fight the wars and design the airplanes and come back and help design and build and test them,” he said. “The fact that women are not in this field is a matter of our social order. It may be undesirable.”

By that time, NASA’s focus had shifted entirely to putting a man on the moon, and agency officials said that redesigning flights suits for female astronauts would be costly and time-consuming in the midst of the Space Race. The milestone of sending the first woman to space was left to the Soviet Union, which launched Valentina Tereshkova in 1963. The first American woman in space, Sally Ride, followed suit in 1983.

Ms. Cobb had by then established herself as a missionary and humanitarian force in South America, where she had once delivered military planes to Peru and spent days in an Ecuadoran prison, accused of being a spy for Peru. Flying solo with the aid of hand-drawn maps, she was honored by the governments of Brazil, Colombia, Ecuador and Peru.

The only thing that would take her away from her work, she said, was another chance to go into space — an opportunity that presented itself in 1998, when Glenn, then 77 and a U.S. senator, became the oldest person to fly in space.

A grass-roots campaign to “Send Jerrie Into Space” was launched on behalf of Ms. Cobb, who was then 67 and received support from groups including the National Organization for Women. Traveling to Washington, she met with Glenn and later with NASA Administrator Daniel Goldin, calling for more female astronauts regardless of whether she made it into space.

The mission never came to pass. But Ms. Cobb was there at the launchpad in July 1999, watching alongside other surviving FLATs as Eileen Collins became NASA’s first female shuttle commander. Four years earlier, when Collins became the first female pilot of a shuttle, she launched into space carrying a token from Ms. Cobb: a gold pin in the shape of a Colombian bird, a symbol of the plane she flew in South America.

Indigenous tribes, Ms. Cobb said, had always referred to it as “the bird.”

Early life and background

Geraldyn Menor Cobb was born in Norman, Okla., on March 5, 1931, and the family moved frequently among military bases, settling in Oklahoma City.

Jerrie, as she was always known, was shy and mocked by teachers for her lisp. She found refuge first in the countryside, riding horses bareback across the fenceless prairie, and then in the air. “The sky was the only place I felt really at home,” she wrote in her autobiography.

The daughter of an Army lieutenant colonel, Ms. Cobb started flying at 12, sitting on a stack of pillows and using blocks to reach the rudder pedals of her father’s open-cockpit Waco biplane. She went on to dust crops, deliver surplus military planes around the world, and work at the Oklahoma-based Aero Design and Engineering Co. in the 1950s, as one of the few female executives in aviation.

Ms. Cobb received her private pilot’s license at 16, her commercial license two years later, and by 19 was certified as a flight and ground instructor. She used money she earned playing professional softball to buy a Fairchild PT-23.

“She found a way to work as a pilot, as a woman, at a time when all those jobs would have been listed in the newspaper under the title ‘Jobs for Men,’ ” said Margaret A. Weitekamp, a curator at the Smithsonian National Air and Space Museum and the author of “Right Stuff, Wrong Sex: America’s First Women in Space Program.”

Her aviation career took off in Miami, where she had sought to work as a DC-3 pilot but was told instead to apply as a stewardess. When she overheard Jack Ford, a government contractor, saying he needed help delivering training aircraft to Peru, she signed on and was soon hired on the basis of her log book, which showed more than 3,000 hours of flying time.

Ms. Cobb worked for several years with Ford’s company, Fleetways, and according to news accounts they were engaged to marry when his plane caught fire and exploded in 1955. Her own death was announced Thursday in a family statement, which did not say precisely where or how she died. A representative for the family, science journalist Miles O’Brien, said Ms. Cobb was quite private, and the family declined to provide additional information.

Although Ms. Cobb was always highly regarded by her peers, her public renown has only grown in recent years. She was the subject of an off-Broadway play, “They Promised Her the Moon” by Laurel Ollstein; was featured in a 2018 Netflix documentary, “Mercury 13”; and in 2012 was inducted into the National Aviation Hall of Fame.

Still, she often played down her accomplishments. “I had no gift for greatness,” the hall quoted her as saying.

"I was no pioneer. I was just a girl who never got enough of flying.”
