When a supersonic plane goes faster than the speed of sound, it creates a shockwave causing a sonic boom. The sound you hear after the plane has passed is the shockwave catching up to the aircraft. This can create the illusion that the plane has disappeared along with the sound.
commonly it is a jet plane
Take the bird onto a supersonic plane and, while the plane is in flight, have the bird fly around inside the plane.
Without a proper oxygen mask, a pilot's respiratory system can collapse in a supersonic plane.
You would hear the sound after the plane has passed.
Concorde
A supersonic plane is one that is flying faster than the speed of sound, or Mach 1. A hypersonic plane flies at a speed of Mach 5, so is much faster than a supersonic plane. Mach numbers are used for speeds greater than the speed of sound.
Concorde
Due to lack of O2, the lungs will start breathing anaerobically i.e.; without oxygen. This may lead to cramps.
Supersonic plane
An airplane that travels faster than sound is called a supersonic aircraft.
