So that's because – I didn't realize this.
voice-verified
That's because parts of the plane, like the wings, can experience supersonic airflow even though the plane itself is subsonic, right?
voice-verified
So it's kind of like a mixed airflow.
voice-verified
Makes sense.
voice-verified
These isolated shockwaves, supersonic air flows can cause these mini kind of proto shockwaves.
voice-verified
So we're already starting to see this transition to supersonic flight before you even hit supersonic flight.
voice-verified
And then finally we have – we enter the regime of supersonic flight, Mach 1, right?
voice-verified
At sea level, that's 1,234 kilometers per hour or 767 miles per hour.
voice-verified
At altitude, it gets a little bit lower because of temperature changes.
voice-verified
Okay.
voice-verified
Now, this transition is characterized by the smooth pressure waves of subsonic flight changing abruptly into shock waves.
voice-verified
That's what the key thing that happens when you become supersonic.
voice-verified
the formation of shockwaves.
voice-verified
So basically, the air pressure waves can no longer get out of the way of each other, right?
voice-verified
Because the plane is traveling as fast or faster than sound itself.
voice-verified
So these pressure waves pile up, merging together into essentially this thin, sharp wall of compressed air.
voice-verified
That's a shockwave.
voice-verified
That's the cause of these sonic booms.
voice-verified
Now, Steve, I was going to say here what you had mentioned.
voice-verified
The misconception is that the plane creates a sonic boom...
