No. The Boeing 747 was not designed for supersonic flight , though during testing, it was pushed quite close to the sonic speed: Tom Cole, a spokesman at Boeing Commercial Airplane Co., said original flight tests of 747s conducted in 1969 and 1970 took 747-100 models to speeds of Mach 0.99.
Can passenger jets break the sound barrier?
Supersonic flights are so called because they travel faster than the speed of sound. To do this, the aircraft must break through the sound barrier, which requires an efficient aerodynamic design to reduce drag, and considerable thrust from powerful engines to overcome the turbulence caused by shock waves.
Can a 747 exceed the speed of sound?
As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier , because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.
Do any commercial planes break the sound barrier?
In 2029, United Airlines flights will break the sound barrier —and a 26-year hiatus of commercial supersonic flight. ... Chuck Yeager broke the sound barrier more than 70 years ago, but it was no simple task. As an aircraft approaches Mach 1, lift and control both decrease, while drag increases.
Can a 737 break the sound barrier?
Commercial aircraft ordinarily can't break the sound barrier , because they're not designed to handle the sudden increase in drag and other aerodynamic effects associated with those speeds.
What is the fastest jet in the world?
The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that's more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner.
Why is it illegal to break the sound barrier?
It's against the law. Within the United States, it is illegal to break the sound barrier. ... When you pass Mach 1 , the plane travels faster than the waves itself and that move across the so-called sound barrier produces a large sound, which is the sonic boom.
Has a propeller plane broke the sound barrier?
Propeller planes can probably not break the sound barrier since the propeller, for the airplane to go faster than the speed of sound, must go even faster. This will inevitably cause shock waves powerful enough to even break the propeller.
Has a car broken the sound barrier?
Thrust SSC holds the world land speed record, set on 15 October 1997, and driven by Andy Green, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier.
How fast do you need to go to break the sound barrier?
The moment an aircraft's speed exceeds the speed of sound, it is said to have broken the sound barrier. At what speed do you break the sound barrier? The speed at which you break the sound barrier depends on many conditions, including weather and altitude. It's approximately 770 mph or 1,239 kmh at sea level .
Do whips actually break the sound barrier?
That's a sonic boom, the shockwave created when the tip of the whip breaks the sound barrier. ... It turns out that the cracking noise is actually created by a loop traveling along the whip , picking up speed. And when it reaches the speed of sound, it creates a sonic boom.
Who broke Mach 4?

Can an A380 break the sound barrier?
A modern aircraft such as the Airbus A380 flies at a cruising speed of about 900 km/h. In the air, the answer is no and yes . When an aircraft exceeds 1236 kmh, it “breaks” the sound barrier and creates a sonic boom that sets dogs howling and annoys folks below.
Which country has best fighter jets?
Most Powerful Fighter Jets: A List – US Made F-22, China Made Chengdu J20 and More. USAF F-22 Raptor fighter jet is widely considered the most powerful fighter jet and is not being sold to other countries.
Which is faster f22 or f35?
It has a top speed of 1.60 Mach , and less maneuverability than the F-22 in dogfight scenarios. The F-22 can ramp it up all the way to 2.25 Mach. It climbs at a rate of 62,000 feet per minute whereas the F-35 climbs at 45,000 feet per minute.”
Which country has the fastest fighter jet?
The fastest fighter still in service today is the Soviet -built MiG-25. Mikoyan designed this fighter to be a pure interceptor aircraft. As a result, the Foxbat can sustain a cruising speed of Mach 2.8 and kick it into overdrive with a top speed of 3.2 – not a bad technology for an aircraft that first took off in 1964.
