Jet Breaking Sound Barrier Video – Then the plane flies faster than the speed of sound. Observers hear nothing but the sound of the plane’s engines until the jet passes and the shockwave follows it across their location. That’s when we hear the sonic boom.
Check it out in the video below. Flight records show the flight path from Pittsfield, Illinois, across state lines into Missouri, and then straight back toward Decatur, reaching a top speed of 1,148 mph. The plane landed safely at St. John’s International Airport.

Louis Lambert at 12:30 p.m., less than an hour and a half after take off. In October 1945, the creator of the Mosquito, aviation giant de Havilland, was asked to study a swept back aircraft design, resulting in the DH108.
The Deadly Swallow
It resembled the tailless, rocket-powered Messerschmitt Me 163 used by the Luftwaffe as an interceptor in the latter stages of the war. According to Rod Kirkby, this aircraft was famous because the term “graveyard jump” appeared in the daily life of the pilots of the time, considering their despair of recovery when the aircraft was in a steep dive.
The first DH108 tail prototype, named The Swallow, took to the air in May 1946, piloted by Jeffrey de Havilland, Jr., a test pilot, son of the company’s owner. Modifications were made during the following months, and in July of that year a second prototype was launched for rapid testing.
Although the change was a general success, parts of the blade reached supersonic speeds before others. This was problematic for two reasons: firstly, sound waves are created when the speed of an object approaches the speed of sound.
Because the blades reached Mach 1.0 unevenly, they created pockets of sound waves powerful enough to destroy a propeller. Secondly, noise was another problem. Propeller-driven aircraft are loud enough, but when these spinning blades reach supersonic speeds, the level of noise created poses a threat to the structural integrity of the aircraft and its pilot.

This picture was taken somewhere over the beautiful Pacific where there is a lot of moisture in the air to give visual evidence of a very auditory phenomenon. This jet reached supersonic speeds, creating a condensation cloud around it.
The shutter speed of the camera that filmed this flight was undoubtedly set to a truly amazing speed, probably opening and closing at about 1/4000th of a second, if not faster. As in the case of this aircraft, this level was penetrated by the cockpit area, but not the rest of the body, but only the tail section with the usual vapor cone.
What a fascinating phenomenon to study. This type of jet clearly tends to create such a vapor cone that segments into stages, going from subsonic to transonic and eventually supersonic. Various areas of low pressure and vapor moisture refer to areas that have entered the elite supersonic club known only to humans.
When flying so close to the ground, the air becomes denser and creates more friction and drag – and, anyway, pilots are forbidden from breaking the sound barrier above ground. “You can do it over sea,” he said, “but you can’t do it over land.
High-Speed Propellers
This is one of the problems that the Concorde project suffered, because as Concorde was being developed, the rules changed, and this meant that it could only break the sound barrier over water.” When Chuck Yeager first broke the sound barrier in 1947, it was one of the coolest moments in aviation history, even if it took a while for it to become known to the public.
The impressive feat was accomplished in the Bell X-1 experimental rocket plane, which was nicknamed “Glennis Glam” after Yeager’s wife. Designed with a smooth fuselage and slender, non-swept wings, the X-1 was dropped from a Boeing B-29 Supergaer bomb bay at 25,000 feet.
From there it took off to 40,000 feet and broke the sound barrier at 662 miles per hour. In the years that followed, significant advances were made in supersonic aircraft technology. However, propeller-driven aircraft remain slow, subsonic, laggards today.

The steam cones are created by the shock wave generated by the aircraft as it accelerates. Shock waves are physical effects that occur when an aircraft moves quickly through the air. As the plane picks up speed and approaches the speed of sound – about 767 miles per hour (1,234 km/h) at sea level – shock waves form around the plane.
Rockets Wings And Tails
Across these shock waves, there is a “heterogeneity” of local pressure and air temperature. This causes the air to lose its ability to hold water and vapor begins to form, creating a vapor cone. Clark assured that “there were no reports of damage associated with the incident.”
But the uproar that has left local and state governments scrambling to reassure the public of its safety has raised questions about the lack of attention that has surprised so many. Minutes after the riot, the Illinois Office of Emergency Management stepped in to calm the fears of a panicked public.
IEMA officials said in a statement that the noise disturbance prompted “immediate cooperation between federal, state and local authorities to determine the impact and source of the incident.” Peter Amos, an aviation historian who wrote an authoritative multi-volume history of Miles Aircraft and shared Don Brown’s paper with National Geographic, adds: he didn’t cancel a day when it was partially built, and then spent a lot more money on long.

breaking the barrier was Chuck Yeager in 1947. Since then, the aircraft’s capabilities and speeds have only increased. In honor of the incredible novelty of supersonic speed, let’s take a look at 25 amazing photos of jet aircraft breaking the
sound barrier. Any discussion of what happens when an object breaks the sound barrier must begin with a physical description of sound as a wave with a finite propagation speed. Anyone who has heard reverberation (sound waves bouncing off
distant surface) or has been far enough away from the event to be first seen and then heard familiar with the relatively slow propagation of sound waves. At sea level and under standard atmospheric conditions of 22 degrees Celsius
, sound waves travel at a speed of 345 meters y r second (770 miles per hour). As the local temperature drops, so does the speed of sound, so for an airplane flying at 35,000 feet with an ambient temperature of 54°C, the local speed of sound is 295 meters per second (660 mph).
Shot Down
Most of the theories about how much the Bell X-1 drew on M.52 ideas revolve around this tail. According to Rod Kirkby, Bell Aircraft decided to increase the power of the tail trim after discussions with the Miles design team in case it might be needed.
In test flights around Mach 1 in the X-1, Yeager found the plane’s pitch to be nearly impossible to control. Installing an electrical switch that controlled the slope of the tail – Kirkby calls this addition a “field fix” – solved the problem.
An airplane can create a “sonic boom” any time it is flying at speeds over 750 miles per hour. According to publicly available flight records, the Boeing plane broke the sound barrier at over 40,000 feet for about two minutes.
The propeller-driven XF-88B Voodoo, powered by T-38 turbojet and turboprop engines, was selected as the NACA experimental aircraft. Unfortunately, as it was on the verge of success, the agency abandoned the project. By this time, Yeager had already made history, and advances in jet engine technology had pretty much quelled any interest in high-speed thrusters.

Rod Irwin, chairman of the Aerodynamics Group at the Royal Aeronautical Society, says all the conditions a vapor cone creates break the sound barrier, but the cones are usually drawn at speeds slightly below sound. In aviation, the speed of sound refers to how fast sound waves travel through the air under current atmospheric conditions.
On a dry day at 68°F, that speed is 761 miles per hour. The lower the temperature, the lower the speed of sound, and vice versa. In order to exceed this speed, the aircraft must be able to overcome a large number of adverse aerodynamic effects created by transonic air movement.
These effects include shock waves, turbulence, heat generated by friction, and a significant increase in drag. Together they form a barrier that significantly reduces aircraft performance and makes it difficult, and often impossible, to gain additional speed.
If the aircraft can overcome this aerodynamic barrier, more commonly known as the sound barrier, then a sonic boom is created. Social media sleuths were quick to offer possible explanations. Some wondered if it was an earthquake.
Others suggested an explosion at a chemical plant. WCIA3 Chief Meteorologist Kevin Lighty, a licensed Federal Aviation Administration drone pilot, was one of the first to suggest it was a “sonic boom” created by a jet breaking the sound barrier.
1947: Miles A.2, a 0.3 scale prototype of the full size M.52, is loaded onto a de Havilland Mosquito chassis used as a lift plane. Shortly after launch, the model misfired and fell into a “bomb trajectory”.
With the rocket’s problematic ignition system resolved, a final attempt in 1948 with the A.3 succeeded, reaching 1,074 mph with no sign of instability – not only living up to the M.52’s design, but surpassing expectations.
Ultimately, he says, you need the right climate — the kind of warm, humid air that aircraft operating off carriers can find more easily than most. Then find a cameraman nearby who really knows what they’re doing, and voila, you’ve caught on camera a dramatic cloud of vapor that many of us think of as a sonic boom show split-

The result of this huge low pressure zone is the well known sonic boom, a sound that probably everyone should be able to hear in their lifetime. This may be your explanation. Below is the flight path this morning.
An airplane flies over 1,000 miles an hour. The sea level sonic boom occurs at 750 miles per hour. This plane flew over many parts of central Illinois at over 750 miles per hour. pic.twitter.com/j3ZZdWvIF4 Other achievements of the enclosures include tracking ships, vertical take off aircraft and, as the subject of this article, incredible speed.
The highest official speed recorded for the Lockheed SR-71 Blackbird jet reached a truly surreal 2,193 mph. Although this is the only plane that can fly at this speed, there are many planes that can break the sound barrier, also known as Mach 1. There is love in the sky over the Mediterranean, love on

The training trips themselves are pretty routine. The speed of this particular flight was amazing. The jets produce a wider but softer “sonic boom” the higher they fly. The US Air Force estimated that people could have felt the supersonic impact on Tuesday afternoon up to 46.5 miles from the plane’s flight path.
The challenges included rethinking not only the technology of the wing, but also how to position the pilot and reduce nose drag. Biconvex wings were eventually used and tested on the Miles Falcon trainer aircraft. They had “a very sharp lead and a thinner-to-chord ratio than ever before,” Brown wrote in a project memorandum.
“Because of the finished wing, the aircraft became known as the ‘Gillette Falcon’ after the famous razor blade of the day.” Bancroft noted that the engineers working on the wings were constantly cutting themselves on the leading edges.
One important aspect of the design they both had in common – those straight wings – points to another possible reason for the cancellation of the Miles project, apart from the dire public funding situation facing the post-war Labor government
. After the defeat of Nazi Germany in May 1945, the Allies gained access to data from the Luftfahrtforschungsanstalt in Volkenrode, Hitler’s top secret center for aeronautical research and development. This showed that the Germans had done serious research on the importance of swept wings for shock wave delay and aerodynamic drag at high subsonic speeds.
“The order was given to immediately cancel all high-speed projects that did not use reverse booms,” Brown wrote. “In vain Miles and his team pointed out that the plane was designed for supersonic speed. Also, [Chuck Yeager’s successful plane] Bell X-1 didn’t have swept wings.” Boeing, one of the nation’s largest defense contractors, told the government that Defense Department pilots were taking one of its F-15EX Strike fighter jets
New Eagle II for “final acceptance,” according to sources in the conversation. which is a kind of test drive before closing the deal. At supersonic speed (above the local speed of sound), no sound is heard when an object approaches
to the observer because the object is moving faster than the sound it makes. The sound waves emitted by the object will only be heard by the observer after the object has passed. Referred to these time periods are often referred to as the quiet zone and the action zone. When an object passes over an observer, pressure disturbance waves (Mach waves) are radiated towards the ground, causing a sonic boom. The area where

Further design work would have led to the first British manned aircraft to break the sound barrier, and a high-speed crash would have killed the founder’s son Geoffrey de Havilland Jr. and test pilot John Derry.
The logical explanation for the “boom” was that a military aircraft was testing, causing a sonic boom when breaking the sound barrier, or it could be a meteorite entering the atmosphere. Check your circle cameras. 11:24.
M.52 fuselage plan. Designed to take off and land from the ground due to the lack of a large lake bed that did not have the problem of landing correctly, the rocket plane would never fly, although all the components were available when the project was cancelled.
The aircraft that did this, the American Bell X-1, is on display at the Smithsonian’s National Air and Space Museum in Washington, DC (below).
