Sonic what! Everyone thinks the vapor cone is the sonic boom. WOuld you guys actually do this low over everyones heads. They makes us got 35-40k to do it over Randolph.
So many smooth-brained physics experts in this comment section. Y'all have been watching too many movies - your ears will not suddenly rupture and bleed if you experience a sonic boom. They demo supersonic passes on ships all the time. Great video, sorry about the office chair pilots in your comments.
Thank you, couldn't have said it better. If sonic booms blew out eardrums then what about our boys in WWII around 20mm & 40mm anti aircraft and 5" guns? Anyone that has survived combat for that matter. Many, many things louder than sonic booms and yet no bleeding ears? What an oddity!
True. I heard a F-14 break the sound barrier twice maybe 50 yards to the side of the flight deck when I was in 3rd grade during a Tiger Cruise. Loud, yes. Damaged, no.
You can tell they've never experienced a sonic boom before. I live in the "Thumb" of Michigan and would hear them all the time as I was growing up before they changed the laws because it was affecting the live stock production. The Air Force would do combat training out over Lake Huron and the planes would venture over land at times and break the sound barrier. No one I know had their ear drums blown out, though a few windows got cracked, lol.
That was not a sonic boom just the engines facing their direction after passing. You can''t do that to people that close. We have to fly 35-40k ft over land to go supersonic due to how much damage it can do. Cool thing is, inside the jet you don't hear anything and it fly's smoother, the opposite of what Hollywood portrays. I have in cockpit footage on my IG of going supersonic. But it's not exciting. From within thew cockpit it's just a number you pass.
Remember back before the days of the internet when people thought stupidity was caused by lack of information? Reading a lot of the comments on this video confirms that wasn't it.
@@mikeborgmann at some point, people started giving the same weight to feelings as facts. That, and while feeling completely free to behave rudely and insulting to anyone they please due to internet anonymity, they're also unable or unwilling to admit or accept that they could be wrong to strangers. It's very odd and not something you would think would be how things would change.
I'm ex merchant marine, worked all over the World. On numerous occasions our vessels would get supersonic buzzed by foreign Aircraft when working in their waters. It is utterly insance and shakes the whole ship. The first time I heard a sonic boom close up I thought the ship had blown up lol.
@@marcussterling4954 I would call some cruise ships more like floating cities seeing as the largest aircraft carrier is like 30 meters shorter than the largest cruise ships. And cruise ships have malls, food courts, drinking establishments, cinemas, pools and water slides. So I would say they are more like floating cities in my opinion.
I once heard the sonic boom of a low flying panavia tornado when I was around 5 years old and the whole thing gave me a phobia for loud noises that lasted for like 10 years... but it also started a lifelong fascination for military aircrafts
I had the same issue with gunshots, My ears are literally insanely sensitive, when I was 13 I took a gun class with earplugs AND earmuffs and I still cried like a baby when they shot a glock.
@@grey279 I'm quite surprised I usually have glocks in my memories being rather mildy or moderate in how they sound. do you still feel the same about them or has it changed?
People saying that the plane was a sonic boom, and that the commenters were wrong. But i'm over here trying to find the comments that said it wasn't a boomy
Our F-18's did this a few times during our med-cruise 87/88 on board the USS Coral sea , The air demo's were a great moral booster for the whole crew , Some would drop live MK-82"s about a mile from the ship as well was cool to witness these things in person !
I saw this on tiger cruise on the kitty hawk 2001ish. I'll never forget the complete silence as it approached. I think some don't understand that at close distances, the sonic boom and the actual sound of the jet are very close together and mesh together. At longer distances you'll hear the two cracks distinctly.
I just love to see things where they're either so far away sound reaches you a lot later than light or things moving faster than sound so you see them pass before you hear the sound. So satisfying.
On this particular day, several air demonstratons were held. This manuver was speficically a super sonic fly by. It's indisputable. I shot the video myself.
Thats not a sonic boom at all lol, thats a subsonic flyby, if there was an actual sonic boom, you wouldnt be filming with ears bleeding or severely damaged.
@Bereck Your ears are not going to be bleeding dude. I've been boom'd twice by a B1's, yes its loud. Yes, it can damage things, but its not like a bomb went off or anything like that.
The perks of being in the Navy. I remember ours on the Kitty Hawk returning from Southern Watch. All airshows are tame after seeing the one we had at sea. Makes me nostalgic
My brain steuggles to fathom going so fast youre silent until youve left, like i get the physics but it just blows my mind, id love to see it in person one day
Hi, former professional attack helicopter here, and i can confirm that this aircraft is so damn fast! It's an amazing experience to see it in person, the sound, the speed, everything is perfect!
It completely destroys my mind that these planes move so inconceivably fast that they literally out run the sound they produce and are completely silent to an observer on the ground until they have passed over their heads.
It truly is crazy. The air moving over the plane is literally so fast that it essentially forgets how it's supposed to act in relation to the plane because information can not be communicated down stream. Causing completely different aerodynamic behavior above and below Mach 1.0. So fast that it confuses molecules. Sonic booms are caused by the molecules that where misbehaving because they couldn't react to the movement of their upstream and downstream buddies, suddenly snapping back into conformity with the ambient movements.
@@ericparker163the thing you’re seeing is just air and condensation that couldn’t make it out the way of the plane in time and not sound itself, but still cool
Ah yes. This is definitely a "civilian airspace" It's perfectly normal to see people standing on the top of Super Hornet wings... Boy, oh boy do we have some amazing thinkers in this comment section. Gold star for them 🌟
I love the standing on wing comments. A Super Hornet wingtip mount is rated for 250 pounds due to the wing fold motor, couple of people standing up there is nothing. The only issue is standing on a control surface.
Perhaps the most fascinating thing about this is the blur around the aircraft at around 0:15 - I watched a sonic boom explanation video after this and that blur is a very real phenomenon and not camera quality
Another great catch! Would you be okay with me featuring this in an episode of Weekly Dose of Aviation as well? Of course you will be credited both in the video and in the description as before. Thanks!
I heard a sonic boom when I was at my caravan in Heacham, it's what us older people do...last summer, no windows were broken but the mallards that frequent the site appeared to be slightly shocked for a few minutes. Heacham is on the east coast of England but actually faces west across an area of water called The Wash, and there are quite a few military practice flights over that particular area.
You are the person who acts like you are completely right, first of all sonic boom has the power to shatter windows and make the people's eardrums explode, in that case why the people here are so casual? Sonic booms are banned and they are not allowed around civilian spaces.
@@Handlesbar if it wasn't a sonic boom, then how come we didn't hear the jet coming? This is because the aircraft was going mach. If it weren't we would have heard a rumble as the jet approached the camera. Secondly, the middle of the ocean does not count as a civilian airspace. They are on an aircraft carrier somewhere in the ocean, meaning that they are allowed to go mach. And if sonic booms shatter eardrums, how come there are people there without ear protection? They might have earplugs, but this doesn't mean that they shatter eardrums. And if it did, how come the Concorde (a mach 2 civilian aircraft) was allowed to fly over civilian airspaces at one point? And finally, a .22 caliber rifle generates a sound around 140 decibels, while the average sonic boom generates a sound of around 110 decibels. This means that the average rifle is LOUDER than an aircraft breaking the sound barrier. And you don't hear people talking about rifles shattering eardrums, do you? If you shot a rifle without ear protection, it would cause severe hearing damage, but it wouldn't break your eardrums. Plus, 9mm police service pistols generate a sound at around 130 decibels, and cops fire them without ear protection all the time. In conclusion, they are allowed to do a mach pass because they are not over civilian airspace and sonic booms will not blow up your eardrums as they are quieter than the average service pistol being fired. Research stuff before you make such bold claims. (I did)
Back in Melbourne (Formula One's) in the mid 2000's, they had F18's doing sneaky assed fly by's dropping sonic booms when nobody was expecting! Shit was scary and awesome as hell!
That’s what I’m talking about!!! actual sonic boom of an FA 18 truly breaking the sound barrier!! there’s nothing cooler and the camera work was insane
And I don’t wanna hear anyone telling me that was subsonic that was the most obvious supersonic pass, I’ve ever seen filmed So Far on RU-vid. you could not hear the jet before it passed then you heard the boom and the screaming of its 🍼 massive engines
This is absolutely 100% a sonic boom. The fact that you hear no sound before the jet passes overhead, and then there is a sharp bang as the sound cuts in is a dead giveaway. Anyone who tries to claim that this is not a sonic boom is wrong and misguided. Or trolling. I'm not sure which.
Could be the mic clipping. I am a photographer and film with my camera as well. I have a external mic that clips with loud sounds and when it does there is no sound but not all cameras do that.
77th weapon squadron here I’ve been working on these for 13 years not only that my dad is a retired master chief I’ve been around these planes my entire life one thing I know it takes 666 miles an hour to break the sound barrier, this plane is literally going 661 and the reason I know this is because I’m also a pilot. Lol it’s not super sonic. If you go supersonic on the ground, it would’ve thrown everybody back. Lol Also, you would’ve heard more than 2 to 3 booms lol and you don’t have to take my experience in the department of defense for this you can literally go to something called myth busters, and they already busted this man lol
Living at an active AB is annoying AF. We had jets taking off every 90 seconds, 24 hours a day (was overseas). Usually a pair of F-16s. Trying to talk while outside was a joke.
To anyone thinking that this wasn't a sonic boom. You're Wrong. 1. The cameraman is below. 2. Living on (one of) the "Space Coast", I've heard MANY of them. While they are certainly, "Attention Getters",😳 unless they are at very low altitudes, AND you are in close proximity, 🧐 You'll be just fine (other than your heart skipping a beat). 🤷 3. Most camera microphones simply won't pick-up the sound/ overload (muffled). Just like pointing your camera at the sun (unshielded), the sensors will overload (black spot in the middle).
it is not a sonic boom. 1. performing a sonic boom at an american air show is illegal. 2. the “shock wave” you see is just a vapor cone, which is common when an aircraft moves at transonic speeds in moist air. 3. just because a jet makes a loud noise doesn’t mean it’s going supersonic.
@@1i8m Did you read the part about me living on the Space Coast? Maybe you should come down here and watch a few booster landings and "incorrect me" some more (although the shuttle landings were awesome too).
@@tracewallace23 those aren’t sonic booms, the shockwave generated by a sonic boom is invisible. the phenomenon you’re referring to is a vapor fan. look it up and you will see. there is a common misconception that vapor fan=sonic boom, mostly because of movies and videos like this.
my first sonic boom was at an airshow, we werent at it yet bc we were going the day after but once it jumpscares the croud at the airshow (it always does and im not joking) it accidentl y made a sonic boom when flying over us, it was loud but it goes silent pretty quikley.
Awesome video! I’m overjoyed at it being a legit sonic boom as opposed to vids merely depicting a vapour cone and alleging it’s breaking the sound barrier. In your vid, we got both. He’s banking too! Edit : Thank you 🙏🏻
Fun fact: You can tell it's not sub-sonic because you can't hear the plane until it passes the crowd, because it's going FASTER than the speed of sound. That's how that works :)
i feel so sorry for enemy’s on the other end of that that sound has to be freaking terrifying if you don’t know an attack is comming and this is all you can hear lol
There are a lot of videos claiming to be aircraft breaking the speed of sound - clue is in the "breaking the speed of sound" meaning that you will hear nothing until the aircraft has passed which is exactly what you see here - this aircraft is breaking the sound barrier.
Hearing sonic booms was pretty standard when I was a little kid in the 1950s. We always heard them, and our house windows did vibrate sometimes. Sometimes I heard them when I was outside playing. It just wasn’t a big deal. We were more worried about the Soviets attacking us with thermonuclear weapons back then.
Video: shows the work of pure aerospace engineering and the feats of going past mach 1 and breaking the sound barrier, causing a sonic boom Also video: Shows a clear indicator of a sonic boom, having no sound until the jet passes, and that sound being amazingly loud Comments: no sonic büm 🤓
To the no-boomers who think this aircraft is subsonic, slow down the video. The jet seems to travel roughly 3/4 of its length in one frame. That means the 18m long aircraft is going maybe 13 or 14 metres per frame which puts it at somewhere between 390 and 420 metres per second, which is something like mach 1.15 to mach 1.25 ish, assuming the speed of sound is 340m/s. Didn't have to know anything about aeroplanes to tell that, just had to do some maths. Also there's clearly a sonic boom.
@@HE-162 Fair point, having poked around, right clicking on the video and checking out the stats for nerds reveals it is 30fps, and if frames were dropped to get there that shouldn't matter as long as the video is played in full speed. It's possible I might have checked this 3 months ago and neglected to mention it, I honestly can't remember. But 30fps video, 18m jet, 3/4 of a jet per frame, the only assumptions left are that the video playback is in full speed, and that the vantage point is relatively slow moving. Which seem reasonable, the movements of the camera and the people waving don't seem obviously sped up.
@@tombackhouse9121 absolutely, but the issue is that 30fps is really not enough to measure anything like this with precision, nor does it really matter since this is at most a transonic pass. Transonic speeds are not absolute, and depend on the specific aircraft, air density, etc. Transonic speed is roughly 0.8-1.2 mach. At transonic speed(and even below it), the jet is going to be perceived to arrive and be heard at essentially the exact same time as the sound waves, but do not create a sonic boom. A sonic boom only occurs once all the airflow over the jet is supersonic and the sound waves unite to form a cone, and is incredibly loud…loud enough to disrupt people standing nearby due to the pressure wave(this is why it can crack/break windows) as well as be heard tens of miles away. Additionally, breaking the sound barrier at low level is incredibly difficult, and requires most jets to use every ounce of power they have, and still they may not be able to. The air density is simply too high which is why supersonic flight, and high speed flight in general, occurs at altitude. The f-16 is only theoretically capable of Mach 1.2, at sea level, in perfect conditions at full afterburner. At full afterburner it has roughly 9 minutes of flight time. For many supersonic jets it’s flat out impossible. The f-111 was capable of Mach 1.3ish at sea level, requiring both engines in afterburner, and when it was put into service it was the only airframe in the world capable of sea level supersonic flight. At transonic speed the drag is the highest it will be, and explains why the power necessary for achieving sea level supersonic flight requires so much power. The drag actually decreases once the sound barrier is broken because the air is no longer flowing over the jet in both subsonic and supersonic speeds, and this also explains why supersonic flight can be somewhat more fuel efficient than transonic. These high speed passes that we see, the alleged “supersonic” ones, are transonic or below transonic. When the jet passes us close at 600+mph, our brains simply can’t register the order of the sound vs when we see the jet pass, which makes sense, as both the jet and the sound are practically arriving together. This is why I say that measuring by the low frame rate isn’t really of any use(except a rough ballpark), because besides there being no other stable reference points, the jet is moving so fast that 30fps is not enough to accurately measure the speed and so offers no proof of the pass being supersonic. It gets you close enough to confirm what is already clear from the video, that the pass was transonic or high subsonic, but unequivocally not supersonic. It just appears that way because a jet at full power, possibly in afterburner, traveling near the speed of sound, is gonna be incredibly loud and abrupt when they arrive. Unfortunately loud and abrupt is not the same as a sonic boom
For further confirmation, assuming the video audio is in sync, you can calculate the speed of the aircraft from the sound delay. Which according to my calculations is roughly Mach 1.1. Depending on the air temperature and humidity. For anyone interested, the relevant equations are, you'll have to do some simple algebra to find the answer from these equations: a=sqrt(1.4*287*T); a = local speed of sound (meters per second), T = ambient temperature (kelvin) theta=arcsin(1/Ma); Ma = Mach number Ma = w/a; w = speed of the aircraft (meters per second) Adj = Op/tan(theta); Op = shortest distance of aircraft from camera (meters). Adj = 'x' axis distance between the point where the shockwave hits the camera, and the aircraft t=Adj/w; t = Time of the sound delay.
@@HE-162 At mach 1.2 at this distance you'd expect a roughly 0.5-1.5 second delay (Large window because distance is uncertain from the video). It would not be perceived as coming at the same instant. A sonic boom is generated whenever an object exceeds mach 1 by any amount,. The sonic boom is the sound of the edge of the shock cone generated by supersonic movement and is present at all times, though it is perceived as an instantaneous effect by observers because the edge of the shock cone passes them at the the speed of sound. At speeds very close to mach 1 there won't be very much delay, but even at something like mach 1.01 the delay physically is there and at a large enough distance between aircraft and observer it can be perceived without special equipment. Also, transonic isn't really a hard and fast rule, and the brackets you've placed on that range are largely arbitrary. The term transonic is used to describe a scenario where some parts of relative fluid flow are locally supersonic and some parts are locally subsonic. However, physically, being transonic isn't really a thing. Only subsonic or supersonic flows exist in a physical sense. I would recommend F. White - Fluid mechanics. It's a fairly good entry level textbook on fluid mechanics with a good introductory chapter to supersonic flows that will help you understand this. Can be easily found as PDF.
I remember as a young boy living in the Salt Lake Valley, I would hear sonic booms all of the time until the FAA restricted the air speed of fighter flying out to the range in the west desert.
Every single spectator other than the military guys are watching this take place thru their phone. Nobody just appreciats things in real time, they'd rather watch it thru a 4 inch electronic screen. SMDH...
The listener will hear no sound until the sonic boom reaches them because as the source passes by, the frequency will be infinite. This is caues of the doppler effect. The sound waves are litterly on top of each other, which is a lot of energy.
I haven’t read it yet but who is arguing a sonic boom here? This is clearly a sonic boom. The legacy F18C will super cruise at Mack 1.04 at angles 30. Fun fact! A lot of people don’t even know that. My father worked on these incredible platforms in the navy, my favorite jet by far.
Yep, thats a real one. Even the auto-equalizing function of the mic could barely cope. Thanks for posting an actual one. There's a reason they dont do that at airshows! BLAM!
Crazy how many people are trying to claim that this is not a sonic boom. It is clearly and distinguishably a sonic boom. I can’t help but wonder if there’s a bunch of smooth-brains from some other anti-science channel that for some reason took up arms against this video in particular?
It was NOT a sonic boom. 1. Jets are prohibited from breaking the barrier below 30,000 feet, 2. If the barrier were broken that close to land, everyone's ear drum would be ruptured and windows all around would be shattered. Do some research and educate yourself.
@MikeNunya...Type in Mythbusters Sonic Boom... They teamed up with the US Military to prove/disprove your theory. Guessing if their proof isn't proof enough for you, nothing will be...
I don't know what everyone is going on about in the comments, I've played a LOT of Microsoft Flight Simulator and this is clearly Mach 5.5. The speed of sound at lake level is 1235 KM/H, or 60 frames per second. There were only 11 frames between the plane flying by and the sound reaching the camera. 60/11 is 5.5. Easy.
Anyone claiming this isn't a sonic boom, i recommend reading the Wikipedia article on sonic booms. The pictures in that article demonstrate clearly why this was a sonic boom. Ie, the sound wave suddenly hit the camera after the plane had already passed because the sound could not keep up with the aircraft and thus formed a sound cone behind it. If you do the math (Pretty basic, back of a napkin stuff), assuming fairly typical weather for the region, you can calculate from the videos sound delay that the aircraft must having been traveling around mach 1.1.
I was working at Edwards Air Force Base once and outside there must have. been two jets playing with each other up where you could barely see them. The caused multiple sonic booms. And of course here in Orlando we were frequently treated to that double sonic boom from the Space Shuttle.
I can appreciate your skepticism, but one, this maneuver was preformed at sea, not over ground, and two, it was specifically a tactical demonstration of breaking the sound barrier. Everyone onboard is issued ear plugs. @@NYG2012
Ok. My mistake. I thought it was airshow over land. Didn't see the water. I was very tired last night after getting home from Stadium Series NHL game. Two F18 Super Hornets flew over at the end of the national anthem. @@ridefreeordie
