How cool is it to break the sound barrier? THAT cool!

Seeing the video above makes you remember that life beats movies, no matter what. The sound barrier is the speed at which a vehicle need to fly/run in order to beat the speed of sound (1,236 kilometres per hour or 768 mph at sea level, via wiki). And it looks pretty darn awesome, let me add.

UPDATE: What you see in the video above is the compression wave that occurs at transonic speeds, from Mach 0.8 to Mach 1.0. The aircraft doesn’t break the sound barrier so close to the viewers. In airshows and so close to people it is not allowed. Thanks to the commenters of this post for this info.

The cloud you see forming there is called a Prandtl-Glaubert singularity. More on this here.

During 1950s the sound barrier has been definitely defeated by human. Kinda feeling proud of those aircrafts, like FA-18 “Super Hornet”, from the images above. Currently, war aircrafts reach easily Mach 2. Cool. Via [One Cool Thing A Day].

Also, let’s learn about the physics behind a sonic boom:

I am a pilot and he did break the sound barrier and to all you morons on here for your ear drums to bleed you need to be right up next to it and for that to happen your ears are the least of your problem your body would be torn to shreds when the sonic wave hit, and if you don’t believe me look at a 50 cal sniper when it misses the target by a foot his arm or head or something will get ripped off and remember the bullet missed the shock wave hit so yeah take it from some one who does this shit for a living. I’m a u.s Air force pilot and my brother is a 9th infantry sniper.

killaj, you are a mental midget. a super hornet cant even break the sound barrier on the deck, straight and level. your sniping comment is equally as obtuse. if you are a pilot (of any kind) then we are all in trouble.

…and you’re full of shit son. I’ve spent a lifetime in Naval aviation and can tell by what and how you write that you are: A. Not telling the truth. B. Not an officer in any branch of the service. C. Know very little about flight physics or physics in general. D. Totally clueless about ballistics. E. Might have a brother in the service.

Transonic pressure occurs at supersonic speed where airflow is moving both at supersonic and subsonic speeds

Yep, compression wave, not sound barrier. Had he broken the sound barrier at that altitude just about everyone on that beach would have had their eardrums burst.

There is a reason it’s never done under 10,000 feet unless FAA clearance is given.

This is true except that he definitely did break the sound barrier, it was part of the air show. you can observe the results by the reaction of the camera and all the people.

Your comment about breaking people’s eardrums is ridiculous. go watch the sonic boom Mythbusters on youtube. It is loud, but not THAT loud.

yup, that crowd of obvious aeronautical engineers totally knows exactly what happens when a plane breaks the sound barrier. he didnt break the sound barrier, if he did, there wouldnt be oohs and ahhs, there would be screams of pain as blood ran out of everyones ears

When we were at sea, our fighters would break the sound barrier next to the boat on occasion and it isn’t what you think. It’s cool to see and loud as hell but it’s not “ear bleeding” loud, it won’t even make your ears ring. Shooting a magnum or high-powered rifle without ear protection would do you more harm.

From the wiki page: In aeronautics, transonic speed refers to the condition of flight in which a range of velocities of airflow exist surrounding and flowing past an air vehicle or an airfoil that are concurrently below, at, and above the speed of sound in the range of Mach 0.8 to 1.2, i.e. 600–900 mph.

Nice…but quotidian. I’m waiting for the Skunk Works to come out with the first inter-galactic craft to break the LIGHT barrier.

it does break the sound barrier, it was a humid day so compression showed up alot more, and as for bursting ear drums? absolutely not, ive stood on the ground with an f15 flying at 1,500ft out in the range near nellis and breaking the sound barrier cant really affect a human being. maybe some ringing ears, but not bursting ear drums

Check this out:
At transonic speeds intense low-pressure areas form at various points around an aircraft. If conditions are right (i.e. high humidity) visible clouds will form in these low-pressure areas as shown in the illustration; these are called Prandtl-Glauert singularities. These clouds remain with the aircraft as it travels. It is not necessary for the aircraft as a whole to reach supersonic speeds for these clouds to form. It is also a build up of shock waves.

Which means that the aircraft not necessarily broke the sound barrier.

I was not there when this guy broke the sound barrier but many many times I have heard the sonic boom and my eardrums were not affected at all. Your ears are more likely to bleed at one on the pop concerts than from a sonic boom.

No, the sound barrier was not broken in this video, it was a good view of transonic flight. The pressure wave is visible because of the moisture in the air. In dry, desert-like conditions you would probably see little or no condensation in the transonic wave.
