Can a 747 break the sound barrier?
4 Answers. 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.
How fast is the sound barrier in kph?
767 mph
At 68° F the speed of sound is about 343 m/s or 767 mph at sea level. Exactly why is this speed called the sound barrier? A plane produces sound that radiates out from the plane in all directions. The waves propagating in front of the plane get crowded together by the motion of the plane.
What is the fastest combat jet?
Mikoyan MiG-25 fighter
The fastest combat jet is the Russian Mikoyan MiG-25 fighter (NATO code name `Foxbat’). The reconnaissance `Foxbat-B’ has been tracked by radar at about Mach 3.2 (3,395 km/h 2,110 mph).
Do bullets create 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.
What is the mph that breaks the sound barrier?
On 21 August 1961, a Douglas DC-8 broke the sound barrier at Mach 1.012, or 1,240 km/h (776.2 mph), while in a controlled dive through 41,088 feet (12,510 m). The purpose of the flight was to collect data on a new design of leading edge for the wing. [35]
How fast to break the sound barrier?
by · 24/01/2015. Breaking the sound barrier means exceeding the speed of sound at 12,192 metres (40,000 feet), that’s about 1,062 kilometres per hour (660 miles per hour).

What is the KSP sound barrier speed?
As was discussed above, it varies with temperature (and temperature varies with altitude and latitude and day/night). 343m/s is the speed of sound at 15 C (288 K or 59 F), which is the reference temperature at sea level for the standard atmosphere, but is most certainly not the temperature at KSC during either day or night.
