How a decorated fighter pilot became the first American to orbit our planet
In short: John Glenn was a trailblazing aviator who transitioned from combat missions in three major conflicts to the frontier of space. As the first American to circle the Earth, he transformed from a military test pilot into a national icon, eventually returning to orbit at the age of 77.
Born in 1921 in Cambridge, Ohio, John Glenn developed an early fascination with flight, building model airplanes and earning his pilot license through the Civilian Pilot Training Program in 1941. His military career saw him serve as a fighter pilot during the second global conflict, the Chinese Civil War, and the Korean War. During his service, he flew 57 combat missions in the Pacific and 63 in Korea, earning a reputation for fearlessness and tenacity, famously returning to base with hundreds of flak holes in his aircraft.
In 1957, Glenn achieved the first supersonic transcontinental flight, a feat he dubbed Project Bullet, which cemented his status as a premier test pilot. This expertise made him a natural candidate for NASA's Project Mercury. Selected in 1959 as one of the original Mercury Seven, Glenn helped design the cockpit and control systems for the spacecraft. His historic orbital mission on February 20, 1962, aboard Friendship 7, was fraught with technical challenges, including a faulty sensor that falsely indicated a loose heat shield, forcing him to navigate manually during re-entry.
Following his NASA career, Glenn transitioned into politics, serving as a U.S. senator from Ohio for 24 years. Despite his fame, he remained deeply connected to aviation, culminating in his 1998 flight on the Space Shuttle Discovery. At 77, he became the oldest person to enter Earth orbit, marking a unique legacy as the only individual to serve in both the Mercury and Space Shuttle programs. Glenn passed away in 2016, leaving behind a record of service that spanned from the early days of propeller-driven combat to the modern era of space exploration.
