Mach 1 is the speed at which you break the sound barrier. The speed of sound, or Mach 1, at sea level and under "standard condition" is:
At speeds of 950 to 1,000 km/h (590 to 620 mph) the air flow around the aircraft reaches the speed of sound, and it is reported that the control surfaces no longer affect the direction of flight.
The sound barrier is a term associated with the speed of sound in air. In that light, breaking the sound barrier is done with speed and not with a loud (many decibel) sound. We don't see anyone breaking the sound barrier by exceeding "x" number of decibels, but by exceeding the speed of sound in air.
The speed of sound in air is about 343 meters per second, which is about 1,126 feet per second. That's about 1,236 kilometres per hour, or about 768 miles per hour. To break the sound barrier, a speedster would have to be moving faster than that figure. And because of the shock waves that the vehicle would have to pass through when breaking the sound barrier, that speedster would probably "feel" vibrations in the vehicle when passing through the sound barrier.

Technically speaking yes it can, because the definition of air force one is any air force plane that the president is in so for an example if a president decides to fly in an Air Force fighter jet like the F-15 his call sign would be air force one and it could break the sound barrier, but traditionally speaking the plane he flies daily can not break the sound barrier. The VC-25 (Boeing 747) the President typically flies is not supersonic within its normal flight envelope. That being said, a DC-8 once did break the sound barrier in a shallow dive as part of a controlled test, so it is theoretically possible for commercial airliners to break Mach 1, but strictly speaking a 747 is not a supersonic aircraft.
791 mph.
762 mph at sea level breaks the sound barrier
at the speed of sound, 768 mph, it would take 891,837 years.
35,000 mph or mach 45 (45 times the speed of sound)
No helicopters can break the sound barrier. The fastest speed achieved be a helicopter is 249 mph.
At 700mph( its' ability to go 600 plus 100 more pushing him) it already broke your speed of sound barrier of 660mph.
He broke the sound barrier October 14, 1947.
You break the sound barrier by moving at a speed that is faster than the speed that sound travels. In dry air, sound moves 768 mph which about 1 mile in 5 sec.
762mph at sea level.
About 700 mph on land
Yes it reached a speed of 763 MPH in Nevada in 1997. It had an F4 Phantom Jet engine.
Because breaking the sound barrier requires exceeding the speed of sound. The speed of sound is approximately 761 miles per hour at seal level at an the air temperature of 59 degrees Fahrenheit.
He has to travel at more than 760mph.
Yes, the Blue Bird car broke the world land speed record in 1964 by surpassing the speed of sound, reaching a speed of 763 miles per hour. The achievement was made by driver Donald Campbell at Lake Eyre in Australia.
It is a car that will do over 1000 mph and break the sound barrier it was also made by ssc the company that made the 1997 thrush ssc car that is currently the fastest car in the world but is yet to be beaten by the bloodhound.
About 750 mph. The speed of sound.
