@smallahmeat: A supersonic jet can appear to be silent from the ground until after it has passed because the aircraft is traveling faster than the pressure disturbances it creates can propagate through the air. Once the aircraft exceeds Mach 1. its individual pressure waves cannot spread ahead of it Instead, they pile together into a three- dimensional shock-wave pattern called a Mach cone, trailing behind the aircraft The angle of this cone depends on the aircraft's Mach number When that shock wave reaches ar observer on the ground, the sudden change in air pressure is heard as a sonic boom. The important detail is that the boom is not produced by the aircraft "breaking the sound barrier" at one particular instant; a supersonic aircraft continuously generates shock waves along its flight path. Because sound travels through the atmosphere at a much lower speed than the aircraft itself, the et can alreadv be far ahead-or even out of sight--when the shock wave reaches you. At 55,000 feet, NASA notes that a sonic boom can take almost a minute to reach the ground. Have you ever heard a sonic boom and realized the aircraft was already gone? #SupersonicFlight #SonicBoom #Physics #Aerodynamics #Science

SappyTO_COOL :

Yeah cus that’s what happens when you travel faster than sound

koa :

isn’t that the doppler effect or smth

PaperCup🇧🇷 :

Imagine smth faster than light and you dont see it coming till its past you (i know its impossible im js sayibg)

Ditty Winkles :

Makes even more sense when you remember that sound is just pressure changes in the air, we all exist in a world full of invisible soup ✌

🤷 :

I heard it before it passed me

Enormous Deer :

The jet sound reminds me of Top Gun on the NES

Brendan Brandybuck :

This is actually not true for supersonic jets that “throw” sound in the front direction instead of the back (as shown in video). A supersonic jet that “throws” sound ahead can actually be heard before it passes.

/home/rageinducedtumor :

nice name bro

ydhdkdjdidjr :

no it's not

praefervidus :

The acoustics aren't exact, they don't account for the sound waves bouncing off the ground, which creates a distinct rising pitch effect after the plane has passed you

J :

evil doppler

Tyler :

Last one sounds like supreme king haki

sploof :

that username😭

Quarky Neutrino :

I swear I heard the start of I’m Blue by Eiffel 65

✝️Andy✝️🇻🇦 :

You could say it’s faster than sound

WEEZUS :

Dat explains y when u finally do hear one and u lookin for em it’s damn near gone already

Silas :

Can you simulate how Boom supersonic plans to reduce noise by “bouncing” the waves off the atmosphere?

snazzyteasle :

i remember i was camping and suddenly all I hear was an instant loud roar and i look up and it was 3 jets

Taeko :

This is always a grievance of mine in tv shows/movies, fast characters appear out of thin air with no sonic boom or shockwave

Suzy (Rebirth) & Eric-Shun :

Turkeysandwhich :

Them blokes flying them propeller planes right above your house

Earlgzuz :

Just saw mr.onomatopoeia_tiktok warthog

ThatNggaDawg :

It goes on and on and on

Asher :

What’s this video called on yt?
