SONIC BOOM

Hi,you can to continu.
SONIC BOOM:The loud noise associated with a shock wave. Sonic booms are commonly caused by supersonic aircraft.From a distance,the sonic boom sounds similar to thunder. At close range it can be physically damaging or deafening. Because of the inherent possibilities of damage or injury from a sonic boom, aircraft generally do not travel at speeds of Mach 1 or greater at low altitudes over populated areas. Bye to next time.
