On Oct. 14, 1947, Lt. Col. William “Chuck” Yeager became the first person to break the sound barrier in a piloted aircraft. Yeager’s X-1 aircraft reached a speed of Mach 1.06 (about 755 mph).
The sound barrier is the point at which the speed of an aircraft breaks the sound barrier. The speed of sound is about 767 mph. When an aircraft travels faster than the speed of sound, the air pressure in front of the aircraft is greater than the air pressure behind the aircraft. This causes the air to compress and the aircraft to heat up.
The X-1 was a small, rocket-powered aircraft. It was designed to break the sound barrier. On Oct. 14, 1947, Yeager took the X-1 on its first flight. The X-1 was carried to an altitude of about 25,000 feet by a B-29 bomber. Yeager then fired the X-1’s rocket engine and climbed to a speed of Mach 1.06.
Yeager’s achievement was a major milestone in aviation. It demonstrated that aircraft could travel faster than the speed of sound. This opened the door to supersonic flight.

Which aircraft first broke the sound barrier?
On October 14, 1947, the United States Air Force (USAF) announced that an aircraft had broken the sound barrier. The aircraft was the Bell X-1, and the achievement was the culmination of the Bell Aircraft Company’s research and development program.
The Bell X-1 was a small, rocket-powered aircraft that was designed to test the limits of high-speed flight. On October 14, 1947, pilot Chuck Yeager successfully flew the aircraft faster than the speed of sound, becoming the first person to break the sound barrier.
Since its first flight, the Bell X-1 has been widely recognized as one of the most important aircraft in aviation history. In 1953, the aircraft was awarded the prestigious Collier Trophy, and in 1976 it was inducted into the National Aviation Hall of Fame. The Bell X-1 is also featured on the United States postage stamp, and a replica of the aircraft is on display at the National Air and Space Museum in Washington, D.C.
Has a 747 ever broken the sound barrier?
The speed of sound is a famously difficult barrier to break. Planes and other objects tend to experience a lot of drag as they approach the speed of sound, and it can be difficult to get enough lift to break through.
That said, there are a few occasions where planes have broken the sound barrier. The first was in 1947, when a modified British Gloster Meteor jet fighter achieved Mach 1.03. In 1969, an American XB-70 Valkyrie bomber reached Mach 1.6. And in 1996, a British Avro Vulcan bomber reached Mach 2.
But what about passenger planes? Have any ever broken the sound barrier?
The answer is yes – but only once. In February of 2003, a British Airways 747-400 jet reached Mach 1.4. It was the first and only time a passenger jet has broken the sound barrier.
So why don’t passenger planes break the sound barrier more often? The answer is mostly because of the amount of drag that planes experience as they approach the speed of sound. In order to break through the sound barrier, a plane needs to produce enough lift to overcome the drag. That’s a lot harder to do with a passenger jet, which is why most planes stick to speeds of Mach 0.85 or below.
Did a Spitfire break the sound barrier?
On October 7th, 1947, pilot John Derry flew his Spitfire Mk.XIV at 763 mph (Mach 0.92), becoming the first person to break the sound barrier in a propeller-driven aircraft.
Born in 1920, John Derry joined the RAF in 1938. He flew Spitfires during the Battle of Britain, and was awarded the Distinguished Flying Cross for his actions.
In October 1947, Derry took off from RAF Tangmere in a Mk.XIV Spitfire. He reached 763 mph (Mach 0.92) in a shallow dive, becoming the first person to break the sound barrier in a propeller-driven aircraft.
Derry’s achievement was not widely publicized at the time, as the UK was in the grip of the Cold War and the news was not seen as being in the best interests of national security. It was not until the early 1990s that his accomplishment was recognized and celebrated.
John Derry passed away in 2008, at the age of 87. He was the last surviving pilot to have flown in the Battle of Britain.
What was the first airplane to break the speed of sound?
The first airplane to break the speed of sound was the Bell X-1. On October 14th, 1947, Chuck Yeager piloted the X-1 and achieved a speed of Mach 1.06. This was a major accomplishment for the aviation community, and it ushered in a new era of high-speed flight.
Who broke Mach 4?
On October 14th, 2014, a manned aircraft achieved a speed of Mach 4. This milestone was reached after years of research and development by the United States Air Force and Lockheed Martin. However, the question of who broke Mach 4 still remains a mystery.
While the exact identity of the pilot has not been released to the public, some have speculated that it may have been Chuck Yeager, the first man to break the sound barrier. Others have suggested that it may have been one of the pilots from the Lockheed Martin team.
Whatever the case may be, the achievement of Mach 4 is a significant milestone for the United States Air Force and Lockheed Martin. It is a testament to the hard work and dedication of the team of engineers and pilots who have been working on this project for many years.
Who broke the speed of sound first?
The speed of sound is a measure of how fast a sound wave travels through the air. It is about 340 meters per second, or 767 miles per hour. In the early 1900s, people tried to break the speed of sound. Some people claimed to have broken the speed of sound, but their claims were never proven. In 1947, Chuck Yeager proved that he could break the speed of sound. He did this in a plane called the X-1.
Do bullets break the sound barrier?
Do bullets break the sound barrier?
The short answer to this question is yes – bullets can and do break the sound barrier. However, there is more to it than that. In order to understand how and why bullets break the sound barrier, it is important to first understand what the sound barrier actually is.
The sound barrier is the point at which sound travels faster than the speed of sound. This occurs when the air pressure in front of the object travelling faster than the speed of sound is greater than the air pressure behind it. This difference in pressure creates a shockwave that travels with the object, and is what we hear as the sound of a sonic boom.
So, why do bullets break the sound barrier?
When a bullet is fired from a gun, it is travelling much faster than the speed of sound. This difference in pressure creates a shockwave that travels with the bullet, and is what we hear as the sound of a sonic boom.
While the sound barrier is usually associated with aircraft, it can also be broken by other objects, such as bullets. In fact, bullets can break the sound barrier at speeds as low as Mach 1, which is much slower than the speed of sound in air (Mach 1 is about 767 mph).
So, what are the consequences of a bullet breaking the sound barrier?
The main consequence of a bullet breaking the sound barrier is the sonic boom. This is a loud and powerful noise that can cause damage to objects in its path. It can also cause hearing damage to people who are close to the sound.
In addition to the sonic boom, there can be other consequences of a bullet breaking the sound barrier. These include shockwaves, which can cause damage to objects in the bullet’s path, and turbulent air flow, which can affect the accuracy of the bullet.
