60,000ft.
In 1972 demonstrators greeted the Concorde as it arrived at Sydney airport. The aircraft’s sonic boom when it broke the sound barrier was hugely loud on the ground even from 60,000ft, causing both environmental and cultural disturbance.
At what altitude can you break the sound barrier?
This slotted-throat approach allowed accurate data collection as air was efficiently channeled around the models and speeds crept up to and slightly past the speed of sound: roughly 760 miles per hour (1,223 kph) at sea level and 660 mph (1,062 kph) at altitudes of 35,000 feet (10,668 meters) and above.
Can the Concorde break the sound barrier?
Concorde is, of course, a well-remembered aircraft. It could fly at speeds over twice the speed of sound, cutting London to New York flights down to under three hours. Flying supersonic creates a sonic boom, though.
At what altitude does Concorde go supersonic?
60,000 feet
Concorde had an average cruise speed of Mach 2.02 (an airspeed of around 2140 km/h or 1,330 mph) with a maximum cruise altitude of 60,000 feet (18 300 metres). It was an ogival delta-winged aircraft with four Olympus engines originally developed for the Avro Vulcan strategic bomber.
Did Concorde passengers hear the sonic boom?
Flying in a supersonic aircraft
The short answer is – no, they don’t hear the sonic boom. Pilots and passengers cannot hear the sonic boom created by their own plane because they are at the head of the Mach cone. In simple words, they are moving so fast that the sonic boom doesn’t get a chance to catch up to them.
Has a 747 ever broken the sound barrier?
Key. While aircraft are put through extreme testing during their certification, these are never intended to be actually faced. The 747-100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.
At what altitude does sonic boom stop?
For an aircraft flying at a supersonic speed of about Mach 1.2 or less at an altitude above 35,000 feet, the shockwaves being produced typically do not reach the ground, so no sonic boom is heard.
At what Mach is the sound barrier broken?
It’s approximately 770 mph or 1,239 kmh at sea level.
Can the Red Arrows go supersonic?
This enables the Hawk to travel at an impressive maximum speed of 645 mph. Whilst diving, the Hawk can reach a top speed of Mach 1.2.
Do bullets break the sound barrier?
In fact, bullets can move fast enough to break the sound barrier. Contrary to what the name might suggest, the sound barrier is not an actual wall or barrier. Rather, it is the hypothetical limit to the speed an object can travel before it exceeds the speed of sound.
Can a plane fly at 60000 feet?
Question: What is the highest altitude an airplane can fly? Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet.
What aircraft flies the highest?
Concorde (of course, no longer operational) was rated to fly up to 60,000 feet. And many private jets operate up to around 45,000 to 51,000 feet. And if you introduce military jets, the SR71 holds the record (for normal flight) at 85,000 feet.
Do planes fly at 50000 feet?
The highest that a commercial airplane can fly is 45,000 feet. Most military planes fly at around 50,000 feet and sometimes higher. Some rocket-powered planes can fly as high as 100,000 feet but they are specially designed for this purpose.
Is breaking the sound barrier illegal?
It’s against the law. Within the United States, it is illegal to break the sound barrier. The Federal Aviation Administration regulations are quite clear: “No person may operate a civil aircraft in the United States at a true flight Mach number greater than 1” except in certain, very limited conditions.
Why do we never hear sonic booms anymore?
In the 1950s and ’60s, Americans filed some 40,000 claims against the Air Force, whose supersonic jets were making a ruckus over land. Then in 1973, the FAA banned overland supersonic commercial flights because of sonic booms—a prohibition that remains in effect today.
Can you hear a sonic boom from 60000 feet?
Yes, a sonic boom produced at 60,000′ can be heard on the ground. These measurements are from aircraft with different altitude.
Who broke Mach 4?

Does a whip break the sound barrier?
The tip of a bullwhip is thought to be the first human-made object to break the sound barrier, resulting in the telltale “crack” of the whip. This “crack” sound is actually a small sonic boom. To break the sound barrier, you (or your bullwhip) must exceed about 770 mph at sea level.
Has any propeller plane broke the sound barrier?
To date, the closest a prop-driven aircraft has come to breaking the sound barrier was in 1944, when a Spitfire in a dive reached Mach 0.92—much controversy surrounds this and other claims, so take it with a grain of salt.
Can you hear a sonic boom from 50000 feet?
An aircraft flying 50,000 feet would produce a sonic boom cone about 50 miles wide. Pilots cannot hear the sonic boom created by their own planes because they are at the head of the Mach cone.
Does a bullet make a sonic boom?
Most bullets make small sonic booms when flying through the air, which to our ears sound like a loud, distinct “crack!” For the Pentagon’s special forces, that makes it hard to be sneaky about what they’re shooting.
