Big hat tip, odins folly:

Mon Oct 14, 2024: I think it's cool

That this was also the day Chuck Yeager broke the sound barrier for the first time, then this guy does it 65 years later without a vehicle…..

Brigadier General Charles Elwood Yeager (/ˈjeɪɡər/ YAY-gər, February 13, 1923 – December 7, 2020) was a United States Air Force officer, flying ace, and record-setting test pilot who in October 1947 became the first pilot in history confirmed to have exceeded the speed of sound in level flight.

Yeager was raised in Hamlin, West Virginia. His career began in World War II as a private in the United States Army, assigned to the Army Air Forces in 1941. After serving as an aircraft mechanic, in September 1942, he entered enlisted pilot training and upon graduation was promoted to the rank of flight officer (the World War II Army Air Force version of the Army's warrant officer), later achieving most of his aerial victories as a P-51 Mustang fighter pilot on the Western Front, where he was credited with shooting down 11.5 enemy aircraft (the half credit is from a second pilot assisting him in a single shootdown). On October 12, 1944, he attained "ace in a day" status, shooting down five enemy aircraft in one mission.

After the war, Yeager became a test pilot and flew many types of aircraft, including experimental rocket-powered aircraft for the National Advisory Committee for Aeronautics (NACA). Through the NACA program, he became the first human to officially break the sound barrier on October 14, 1947, when he flew the experimental Bell X-1 at Mach 1 at an altitude of 45,000 ft (13,700 m), for which he won both the Collier and Mackay trophies in 1948. He then went on to break several other speed and altitude records in the following years. In 1962, he became the first commandant of the USAF Aerospace Research Pilot School, which trained and produced astronauts for NASA and the Air Force.

Yeager later commanded fighter squadrons and wings in Germany, as well as in Southeast Asia during the Vietnam War. In recognition of his achievements and the outstanding performance ratings of those units, he was promoted to brigadier general in 1969 and inducted into the National Aviation Hall of Fame in 1973, retiring on March 1, 1975. His three-war active-duty flying career spanned more than 30 years and took him to many parts of the world, including the Korean War zone and the Soviet Union during the height of the Cold War.

Yeager is referred to by many as one of the greatest pilots of all time, and was ranked fifth on Flying's list of the 51 Heroes of Aviation in 2013. Throughout his life, he flew more than 360 different types of aircraft over a 70-year period, and continued to fly for two decades after retirement as a consultant pilot for the United States Air Force.

Test pilot – breaking the sound barrier

Yeager broke the sound barrier on October 14, 1947, in the X-1.

Yeager remained in the U.S. Army Air Forces after the war, becoming a test pilot at Muroc Army Air Field (now Edwards Air Force Base), following graduation from Air Materiel Command Flight Performance School (Class 46C). After Bell Aircraft test pilot Chalmers "Slick" Goodlin demanded US$150,000 (equivalent to $2,050,000 in 2023) to break the sound "barrier", the USAAF selected the 24-year-old Yeager to fly the rocket-powered Bell XS-1 in a NACA program to research high-speed flight. Under the National Security Act of 1947, the USAAF became the United States Air Force (USAF) on September 18.

Such was the difficulty, that the answers to many of the inherent challenges were like "Yeager better have paid-up insurance". Two nights before the scheduled flight date, Yeager broke two ribs when he fell from a horse. He was worried that the injury would remove him from the mission and reported that he went to a civilian doctor in nearby Rosamond, who taped his ribs. Besides his wife who was riding with him, Yeager told only his friend and fellow project pilot Jack Ridley about the accident. On the day of the flight, Yeager was in such pain that he could not seal the X-1's hatch by himself. Ridley rigged up a device, using the end of a broom handle as an extra lever, to allow Yeager to seal the hatch.

Yeager broke the sound barrier on October 14, 1947, in level flight while piloting the X-1 Glamorous Glennis at Mach 1.05 at an altitude of 45,000 ft (13,700 m) over the Rogers Dry Lake of the Mojave Desert in California. The success of the mission was not announced to the public for nearly eight months, until June 10, 1948. Yeager was awarded the Mackay Trophy and the Collier Trophy in 1948 for his mach-transcending flight, and the Harmon International Trophy in 1954. The X-1 he flew that day was later put on permanent display at the Smithsonian Institution's National Air and Space Museum. During 1952, he attended the Air Command and Staff College.
