I LOVE THIS POST, Leslie that is because it’s about planes. I used to go to airports just to watch the big commercial jets land and have gone to a few air shows too. This is by far to me at least and I hope to you all one of the most interesting photos EVER!

Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects travelling in dry air of a temperature of 20 °C (68 °F) this speed is approximately 343 m/s, 1,125 ft/s, 768 mph or 1,235 km/h.
A sonic boom is the sound associated with the shock waves created by an object traveling through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding much like an explosion. So that means that the sound source (in this case an airplane), will pass by a stationary observer (like yourself) before they actually hear the sound it creates. To help visualize this, check out the animated gif below:
