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 airliners break sound barrier?
Modern aircraft can transit the
“barrier” without control problems. … Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier.
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 happens if a passenger jet breaks the sound barrier?
When the object has passed over the observer, the pressure disturbance waves (Mach waves) radiate toward the ground, causing a sonic boom. … Then, just as the aircraft bursts through the sound barrier, the air is locally disturbed by the resulting shock wave and
the condensation/vapor cloud disappears
.
What plane broke the sound barrier?
On 14 October 1947, travelling 45,000 feet above the Mojave desert in California, Major Chuck Yeager
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 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.
Who broke Mach 4?

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 do we not hear sonic booms anymore?
Why don't we ever hear sonic booms any more?
Noise abatement regulations halted supersonic flight (by civil aircraft) over U.S. land
. The Concorde could still take off and land here because it broke the sound barrier over the ocean, but it's no longer in service.
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
.
Who broke Mach 3?
USAF Captain Milburn G. Apt
became the first man to exceed Mach 3 while flying the Bell X-2 on September 27, 1956. Unfortunately the aircraft went out of control after making history and he was killed.
Who died trying to break the sound barrier?
Chuck Yeager
Do pilots hear the sonic boom?
If you're WONDERing about how pilots handle sonic booms,
they actually don't hear them
. They can see the pressure waves around the plane, but people on board the airplane can't hear the sonic boom. Like the wake of a ship, the boom carpet unrolls behind the airplane.
Can a sonic boom hurt you?
Sonic booms produced by aircraft flying supersonic at altitudes of less than 100 feet, creating between 20 and 144 pounds overpressure, have been experienced by
humans without injury
. Damage to eardrums can be expected when overpres- sures reach 720 pounds.
Why are sonic booms so loud?
Numerous pressure waves combine together to form a single shock wave.
They have the ability to move faster than the speed of sound
. The constant expansion and contraction of air can cause a shock wave that sounds like a loud clap to human ears. This is why a sonic boom can be so loud.
