Bullet Crack: Why is literally no one talking about this?

The weapons paddock used were supersonic weapons. The bullets fly faster than the speed of sound releasing a crack from the bullet itself as it flies overhead. It can be heard in many of the videos taken by victims. This, combined with the massive echo off of all the huge flat and smooth hotel surfaces and concrete surrounding the venue, is why many people are confused as to the direction of the shooter.

I haven't discounted the possibility of a second shooter, but from the videos I have seen, bullet crack and echos seem to be confusing people. I wanted to make a thread on this because I have not seen a single person bring this up. Yes bullets are still supersonic at the distance they were traveling in this case.

Paddock didn't use any weapons you JIDF piece of shit.

...

This has already been discussed, the people you're arguing with are the retards

I havent seen it discussed in the multiple threads i read today, but im glad it has somewhere. The amount of retards or disinfo people in these threads makes them almost unreadable honestly.

kill yourself.

No shit, stupid. It was 20,000 retards that haven't been shot at from an elevated position over 400 yards away. Of course they had no fucking idea what was going on.

There's only one sonic boom, the crack you're talking about, from a supersonic bullet. It happens at the muzzle. The crack doesn't follow the bullet wherever it goes; the bullet would need to be going the exact speed of sound and not slowing down for that to happen. An airplane can do this, a ballistic projectile cannot.

are you retarded?

The bullet itself makes a crack while traveling at super sonic speeds. Same thing happens with a whip crack.

Im mostly talking about retards posting here and creaming their pants listening to bullet crack and echos thinking its multiple shooters.

5.56 isn't super sonic. that's why supressors work on them.

About 2x the local speed of sound, actually.

5.56 is 100% supersonic.

muzzle velocity of .223/5.56
speed of sound

That's your homework you retarded fuck.

5.56 velocity is over 900m/s

Here, this should help.
Suppressors are still useful with supersonic ammunition. They reduce total noise and, in a tactical situation, they make it much more difficult to identify the location of the shooter.

Holy shit you mental nigger.

youtube.com/watch?v=VYfF06CPHMo

I am well aware of this. And yes this video is a good example of sonic booms. I even went and matched up the sonic booms to bullet sounds
But I had not considered that the low frequency sounds weren't echoes but were the actual gunfire sounds.

There were also a lot of surfaces to echo off of depending on video location, but perhaps echoes are irrelevant.

IF multiple shooters, I would imagine that they would be using suppressed firearms. Sure, they can't beat the crack of the speed, but they may hide their presence.

There is enough talk of multiple people, nothing is off the table.

Its pretty self evident in the taxi cab video who was pretty much right under the windows when shooting began that there was a clear and audible difference between muffled distance shots and the shots coming out the window above her cab.

Like theres no arguing at certain points in that video, the muffled distance shots which dummies claim are echos, actually precede the louder gunfire overhead, and thats not how echos work. Theres even a 30 second pause in action where the first sound of gunfire after the 30 seconds is muffled distance shots preceeding the louder overhead shooting, and without the louder shots before those distant shots makes it clear there was a second shooter at a distance.

Fuckin moron can't into physics. I'm really disappointed in the human race this week

Anyone else get that feeling that some gun information just shouldnt be talked about cause its best that normies dont know any better to save them from wicked thoughts?

like sure it wont stop a disaster like vegas but at least their lack of knowledge would insure they are stopped sooner than later.

Probably 90% of the people you meet IRL can't into physics. All this means is that our autism treehouse has been infiltrated by normies.

because thats common sense? the only retards still shilling about a second shooter are Sup Forums trolls looking for a second pizzagate troll so they can get their little rumor on MSM and radio for 5 minutes, or total retards who dont understand highschool level physics

Suppressors work best with subsonic rounds, like AR-15 chambered in 300 blackout.

>That doesn't explain how the echo lasts at least twice as long as the original sound. That isn't how sound waves react on reflection, they don't stretch out. Even if they did, the gunshots would sound as though they were being fired in slow motion. If you take into account the duration, you'd expect the sound to be far slower as well.
Copied from another bread.

It's not just the physics thing. But yeah I getchoo. I'm disappointed by people ready to erase the bill of rights out of fear... Ironically creating a more sinister world for them selfs of their wishes were to be actualized.
All I have to say is SHALL NOT be infringed

I hope someone there had the presence of mind to photograph bullet holes through tent walls etc. If we had access to the sight we could see where the holes point. (look up WWI tactics, they used paper mache fake heads to catch enemy sniper bullets and see where they were coming from)

American education. I thought you cunts knew about firearms? Holy shit nigger. What the fuck.

...

> mfw (((they))) start using this argument to bolster their "what-if silencer" bullshit

To nail down some specifics:
When I say, "lasts at least twice as long", I'm referring to the video of the woman in the taxi. You can clearly hear someone shooting inside the hotel room, then firing upon the crowd. However, it's a short burst lasting no more than two or three seconds. But then you hear the more faint gunshots, and they last six to eight seconds, but they are still firing upon the crowd.

One thing to think about, is even if it's echoes, the sound not only lasts twice as long, but is consistent in pitch and "fire" sound, implying that it isn't distorted in any way, further implying that it's two guns firing at different times.
At one point, you can even hear two guns firing at once, though THAT might actually be an echo.

The bullet cracks at an ear piercing 135 decibels or some such the entire time it remains supersonic, which depending on the ballistic coefficient of the projectile and the length of barrel, let's assume 556. 77gr otm is supersonic and cracking away the entire time it travels out to 900 yards. That is a continuous sonic boom, bouncing off of everything. I

There is a video of a woman being interviewed that was at the concert that said there were also shooters on the ground. Only link I have for it is facebook. I can't seem to find the same videos anywhere else.

book . com /day.blake/ posts/10214392847517819

I forgot to include this in the post, check it out

I don't really trust eyewitnesses all that much, because if you were in a live fire situation in the middle of a super crowded concert, chances are you wouldn't know what the fuck was up either.
Just going to wait for the scene analysis and ballistics analysis to make any judgements in that regard.

Yeah. It's a mess. I haven't seen the vids tho. So I can't relate to the specific scenario. All I know is that a 556 hbullet will take maybe 1/2 a second to travel 400 yards (it's only 2700ft/sec at the muzzle.. Constantly being slowed by drag so it's not a linear equation as it relates to time) anyway. About a half a second. All the while the acoustic shock of its sonic boom is taking time to travel around and bounce off of shit before it gets to your ear. If you were on the ground at 400 meters you would hear the bullet crack long before the gunshot that sent it towards you. Acoustically I'm afraid it's a fucking shit show and it's almost impossible to tell how many shooters without observing muzzle flash.

If a bullet is flying faster than the speed of sound you’re not going to hear it as it passes. Why? THE BULLET IS FLYING FASTER THAN THE SPEED OF SOUND.

Bullet ————————->
Soundwave ~~~~~~]

Sound follows after it passes. And because the mass of the bullet is small the crack is small. In fact, because the supersonic bullets each maximum velocity alonst immediately after discharge (cartridge energy is spent an bullet immediately hits friction) the sound of any “crack”is also subsumed by the sound of the firing.

Learn basic physics.

to anyone who wants to know its called the "thump crack method" if you know it well you can tell how far a gunshot is

>it happens at the muzzle
Are you always such a homo? You'll hear the crack any time the bullet passes you as long as it is still supersonic.
Fuck some people are stupid.
A .223 is supersonic up until 1000 yards.

youtube.com/watch?v=Rb4BP7lZnk0

this video goes over CRACK THUMP in high detail

>t. Never heard a bullet pass by at range.

You hear the bullet BEFORE you hear the shot. Think big picture here leaf. If the bullet is faster than sound and it passes by you at say 10meters. The sound the bullet makes as it passes only has to travel 10 meters where as the muzzle blast hast to travel 400 meters. The bullet will pass over your head.. Almost instantaneously you will hear the crack of the sonic boom of the actual projectile... Followed about a second and a half late by the report of the muzzle blast that had taken that amount of time to reach yu from 400 meters...

Yeah, that's what's so shitty about this whole thing, aside from the whole "dead people" think, is we barely even have enough to dig into it. Anons are doing great work, but there is still so much we don't know.
Here's a video of all the trending clips, purportedly synchronized, so you can see what I'm working off of.
liveleak.com/view?i=8e5_1507160150
The taxi clip starts around 4:00 (a little earlier), and at 4:38 you can hear the gunman fire inside the hotel room. At 4:59 you can hear the first shots being fired, and the echo too.
However, at 5:05 to 5:15 you can hear the part I'm talking about. First few seconds sound like the gun, and then it sounds like another gun farther away is firing for a lot longer.

Or thump crack.. Depending on your azimuth in relation to the bullets vecto r. Say you are well beyond the impact. The target is between you and the shooter.. You will hear the "thump" of the bullet impacting before you hear the report of the rifle. If you are behind the shooter, it is the opposite. Off to the side at varying degrees.. That's where the boom thump shit fails miserably

>If a bullet is flying faster than the speed of sound you’re not going to hear it as it passes.
Good grief. Where did you go to school?
I've hunkered in behind burms and let my friends shoot overhead just to hear what it sounds like. 3Believe me, an object passing you at supersonic speeds makes a crack from the sonic boom. Subsonic just sounds like a whizz but you can still hear it.

Crack happens as long as the bullet remains super sonic, the sonic boom follows the bullet.

So anyone anywhere along the path of a super sonic bullet will hear a sonic boom "whip"

And here's a leaked photo of the door that I think is being shot at around 4:38 when you hear very muffled gunfire. I think it's the shooter blasting at the door.

This.

Blanks fired from the hotel. Cracks, hits, and ricochet sound fx in the PA system. No real bullets.

There he is.

youtu.be/NeL0U4Dgsew

There was no second shooter, this video proves it.

>46 seconds into the video and your statement is disproven
Hurts, doesn't it?

Every time I correct some dickhead over sonic cracks, echoes or the strobe light on the 10th floor another 5 take his place.

It makes me think we're being shilled by disinfo to throw us of the trail of the real juicy info like what the killers motives were?

Exactly. You’ll hear a “thwhip” as the bullet passes, then followed by the crack of the Sound wave.

(Unless, the bullet has travelled sufficent distance that air friction has slowed the bullet speed to where the constant speed of sound overtakes the bullet velocity)

But the other point remains. The sonic boom is indistinguishable from the firearms report because both happen at the same time, and sound travels at the same time. unlike a supersonic jet which is powered and can slip ahead orbehind a sound wave, a bullet immediately losses velocity due to air friction after discharge.

10% shill
20% troll
40% uneducated
20% asking the right questions
9.99% educated
0.01% actually took part and is trying to spread disinformation
These are my rough estimates.

Yeah that's pretty fucky. My here are parts that sound like different audio from different sources happening at once so it's near impossible to pick shutout. If each of those sources were shown independently it would be easier, at least for me, to discern a single shooter from multiple. Shit show

I think it'd be easier too, but I'm having a hard time tracking down the original clips.
Shit just seems too off to me with this, I can't really explain it. There's just too many moving pieces and coincidences for me to shrug it off as a generic attack. Pic related is the best I've got to explain how I feel.

This site is a training ground for bots and AI lol. has been for 3-4 years

Are you fucking stupid? Those were echos in the taxi driver video.

Finally! Some common fucking sense based on hard science. Did I jus say hard science? Sexy...

Once the bullet passes the speed of sound it will make the crack sound. That happens as soon as the round goes off. Ask yourself if jets make a continuous sonic boom when they travel faster than the speed of sound

are you fucking retarded?

yeah, they do. you dumb fucking faggot

Why do you think supersonic airplanes are banned over the US? If it was only one sonic boom then they would just fly over water and get up to speed and fly over the country. It is a continuous sonic boom. Your ears only hear the part of the wave that is hitting them. Fucking piece of human shit.

not disinfo shills, /x/-tier conspiracy idiots who want to turn it into an even bigger happening than it already is

they do, you mongoloid.

holy shit, thanks mate, thats pretty interesting, too bad this board is full of idiots who actively deny science cause its 'jewish' or not fitting their agenda.

I pointed this out last night on a couple of threads and got laughed at. And I still think a m240 was used, the rpm from the audio is too slow for a full auto AR or even a bumpfire.

>this shit again

Yesterday someone linked a video of some old dude, with a fancy gun timer gismo, trying out a bumpfire stock - and he fired at 600RPM.

I see this and instantly wonder why theres a scoped ar in the bathroom thats in perfect view for the picture.

>it creates a sonic blast as it flies overhead, not when first breaking the sound barrier exiting the weapon
I'm sure this bait is 50% of the replies to the OP, so i'll just give you a 1/10 and be on my way

Fucking noobs. A rifle doesn't retain it's initial velocity 400 yards into flight. It has a terminal velocity of 204 miles per hour.

the different sounds are him changing windows, and her driving around

Didnt you know once a plane or bullet breaks the soundbarrier it is constantly cracking everywhere it travels, not just when it breaks it?

Yeah, that is a portion of people on the left. Higher up, people with actual voice in the media and politics pushing this are much more sinister, they know. They know this is a coordinated push, a manufactured opportunity, that's why their narratives and talking points are all the same. You've seen it all year, with Russia-stuff, DACA "cruel" talking points, all of it. The network for this is clearly in place.
I am 100% convinced of this.

I came into this thread just to tell OP to fuck off because he isn't a genius, everyone fucking knows what he posted - the shit about sonic booms and supersonic bullets and shit - but I just have to reply to this top tier bait. Top fucking wow. There are actual people out there that believe this shit and not just shitpost it for (You)'s which is astounding.

Why would that be bait, it true?

First reply owns your dumbass....No muzzle flashes from 32nd floor dummy, Full auto AR VARIANT I THINK NOT

youtube.com/watch?v=GvkzHkJ0RaQ

Also supersonic ammunition if close you can hear if FAR AWAY you can't but you can here the thump of a 550 RPM Heavy MG, 240 series probably, or at tleas the souds of one

youtube.com/watch?v=5UDAT1xQTkw

Paddock was not the shooter, no shooter was on firing from the 32nd floor case closed.

Don't you have a short bus to catch?

That video proves a second shooter and even a very feight burst ain between9 seconds to 11 seconds from very far away Sorry dumbass atomatic fire does not "echo" LOL you clearly have never fired anything, and you are talking to an 0311 I know firearms ive fired so much its ridiculous all kinds of situations, the echo lie is abhorrently detached from reality....

you can hear the crack of the plane if you end up inside a hollow cone that follows it

...

There was no shooter on the 32nd floor so thats a staged scene, maybe the drill psyop crew during the event fired some bullets into it, all the holes appear to be entry not an exit. I love how they parked a rifle on the bipod in the shot, nice staging liars. Also the other door has no bullet holes whatsoever, 64 year old man full auto lol

There were talks of a second shooter from minute 1.
Why not talks of three shooters? four, five?
No, specifically TWO!!
Using these arguments I've been reading of echoes and tricks of the ear it would result in many contradicting claims of number of shooters but there was no such confusion.
People reported specifically TWO!!!

That would render your pic worthlesss

Not enough spent casings on the floor for the amount of carnage, also a lot of head wounds and how does someone also get hit in the chest 3 times? Use your heads.

You clearly drive it, sad shill/retard....Your ignorance of firearms and gunfire is appaling....

Psyop hoax, blanks and fake gunmen...setup fake patsy shitty redherring false stories...and still no muzzle flashes from fully AR Variants from the unbroken clearly STILL REFLECTING GLASS of the Mandalay bay in ALL FOOTAGE...pathetic lies discredited once again

youtube.com/watch?v=5UDAT1xQTkw

youtube.com/watch?v=JpsqirFRdTo&t=361s

9:40 birds eye view no ,muzzle flashes faggots no at the Mandalay bay NONE....get rekt shillnigs

There were actually talks of multiple shooters 3-4 specifically and as verified by FB accounts shooters at other hotels etc. the whole event was all over to confuse, it was a psyop hoax

Fuck all that no gunfire from any ANY FOOTAGE OF THE 32ND FLOOR OF THE MANDALAY..none and the windows are clearly unbusted still reflecting

>automatic fire does not "echo"
Literally what?

>9:40 birds eye view no ,muzzle flashes faggots no at the Mandalay bay NONE.

At that TERRIBLE angle you'd probably only see a muzzle flash if Stevie boy was literally hanging out the window.....

...

The muzzle flash thing got me too. I assume the real shooter/s were the feds or specialists, so for them hiding their position and muzzle flash is part of their expertise. The 32 floor thing and the patsy are just part of the show, the production so the real shooting didn't have to come from there exactly.

Well DC has bullet sound recognition setup around the city, does vegas?

>0311
>smart

someone retarded enough to get tricked into 0311 by a GED sporting recruiter doesn't understand physics.

Mercy, me.

This, were are the casings? Also the forensics of the gun powder spent in that room and paddock.... where is the report?

>The weapons paddock used were supersonic weapons

How old and new are you? Keep up nigga. This shit was discussed forever ago. Literally on the night of. Every gun is supersonic.

Not 45acp
