  2. Sonic boom - Wikipedia

    en.wikipedia.org/wiki/Sonic_boom

    The sound source is travelling at 1.4 times the speed of sound (Mach 1.4). Since the source is moving faster than the sound waves it creates, it leads the advancing wavefront. A sonic boom produced by an aircraft moving at M=2.92, calculated from the cone angle of 20 degrees.

  3. Sound barrier - Wikipedia

    en.wikipedia.org/wiki/Sound_barrier

    [3] [4] The term sound barrier is still sometimes used today to refer to aircraft approaching supersonic flight in this high drag regime. Flying faster than sound produces a sonic boom. In dry air at 20 °C (68 °F), the speed of sound is 343 metres per second (about 767 mph, 1234 km/h or 1,125 ft/s).

    For example, the sonic boom from the Concorde traveling at a speed of Mach 2 (2450 km/h) was about 2.2 psf (0.11 kPa) (pound per square foot). [2] Because of sonic boom intensity, many countries now prohibit supersonic overflight over land or population centres.

  9. The Air Force gave the F-16s permission to fly faster than the speed of sound — something civilian aircraft rarely get to do — as the jets scrambled to catch up with the Cessna Citation.
