I have an application that calculates the ballistic path of a bullet under various conditions that produces something like this (for various zero distances, wind speeds, bullet weights and shapes, drag coefficients and initial muzzle velocities):
suppose we have the (lon, lat, alt) coordinates for each of these points
suppose we have calculated the average velocity based on @kincses-zsoltâs formula (average velocity = N/sum(1/v_i)) for each point on the orange line, including the intersection of the perpendicular lines on the orange line from realDjStew and the microphone
letâs call the intersection of the line from realDjStew with the orange line CR and the intersection with the line from the microphone CM
can you tell me what exactly i need to calculate and add to these tables to facilitate your analysis ?
Fundamentally there is one huge underlying problem with the trajectory analyses:
there is only the first shot that hits Trumps ear and (supposably) the corner of the bleacher to back trace.
FACT All the remanning 7 shots have either only a end impact point or zero info. Meaning the arc of origination is huge and shot origin point is subject to guess work.
Taking another step in the direction of the possibility of 2 shooters, I would claim herewith to present 100% alleged proof that the first shots have been fired from window 3, building 6:
The main reasons why people donât think the 3 shots could have come from window 3, building 6 are as follows:
No window was open at that time.
The trajectory is much too low having the fence and people in the way.
Nobody would be that crazy to shoot out of an open window.
I explained in my previous post the way the two people in building 6 were able to shoot out of the open window without having gotten noticed by anybody. We can therefore move on to point 2.
For those who are interested, please go to this post:
It requires a little bit of willingness to understand, and a lot of people donât like to take the time and try to be objective about it. I understand it, itâs human, especially when it goes against your narrative (@BigTim).
For those who donât believe it, it doesnât matter because the alleged damning evidence I am about to show you will seal the case!
Having found the 1st shot caught on video from body cam: BWC2122110 was a great breakthrough, but it also put the first shot in a very low position, namely in the middle of the window 3:
BigTim (rightfully so!) showed concerns that there is a potential collision with the fence:
Since I was busy debunking many comments with my previous two-window post, I did not have time to back trace the bullet from the new low position. I also waited for some additional important information from @rough_country_gypsy. He did a fantastic job. He provided so much new material to work with. (credit to gypsy ).
So, I finally got around to it and was able to simulate the new position.
Having put the newest data into the my CAD system, oh⊠no⊠I got exactly what everybody was worried about, namely a collision with the fence:
The fact that the data has become so tight and accurate, I do not have any parameters to play with. Everything else would be cheatingâŠ
Was this it, are we coming to a dead end with this 2-shooter hypothesis?
I could not believe that up to now everything was matching up perfectly, but a simple 2 Inch small collision with the fence will debunk the entire story???
Thereâs got to be something out there! So back to Stewarts video for the 500th time, I could find a major finding in his video!!!
WHAT IS THIS??? Obviously, the shooter from window 3 of building 6 had exactly the same problem just like we have, the fence being in the trajectory !!! So, he simply took a pair of pliers and cut out the position that was in the way.
I could not believe my eyes when I saw this. 100% alleged proof that somebody cut out a portion of the fence not to have a collision when shooting!!!
But wait, is it in the trajectory of the bullet line? With a lot of heart beating I then look very carefully into the position where these âcut outsâ were and they turned out to be PERFECTLY in line with the trajectory between window 3 and Trumps ear. It is something locked into space with no debate.
So, the above pictures can seal the whole case, proving without reasonable doubt that the first shot came from window 3! There is absolutely no other explanation to have those cut outs in that exact position of the trajectory between window 3 and trumps ear.
Ironically in the same picture you see the guy from ARJ aggressively kicking out all the people that are in the trajectory with the following sentence that comes to my mind: Get the hell out of our trajectory, because we soon want to assassinate our future president!
Please everybody take 1 min to download this iconic picture. They probably allready changed the fence (maybe @rough_country_gypsy can confirm this point), but it does not matter, because we have it on video.
Here are some screenshots for those who want to verify this finding and please do, I am 99% sure, together with your help we will make it 100%.
The more you write the more you demonstrate youâve never fired a rifle nor used an optic to aim a long range shot. Not going to be shooting thru small breaks in a chain link fence. Furthermore, he said this is the exact spot in the fence. So youâre just manipulating information to fit your skewed narrative.
Iâll concede that that âflashâ in the window âMightâ clear the fence but itâs close, if it were a shot. But it wasnât. It is not close to aligning with any known audio, nor was a window 3 ever opened or removed there.
And this ignores the fact that at no time was the window open, and there is no shooting lane thru/over the >9â tall bleacher thick with standing people. Per YOUR own CAD drawing. The top of the window, around 10â, barely clears the bleachers⊠The middle of the window fails to clear the bleachers and thereâs no lane thru them.
Bonus: You have not yet answered my question asked at least 3 times. What is the âropeâ reflection, and the other reflections in window 2, that are similar to window 3?
OK, @roger-knight. I hate to do this to you, brother. You have to get out of that window because no one else is seeing it but you and Iâm about to break your heart again. I downloaded the photo you shared with the cutout fence notches and yellow arrow. Iâve added the red arrow to point out the âVâ shaped top wire. Itâs the only section along the entire fence where the top wire forms a prominent âVâ. The notched-out fence is clearly in the section to the left of it.
Going back through my files, I found this image where I staked Trumpâs podium location. Itâs not GPS-accurate but I used three different points of reference to measure it out, so Iâm certain itâs very close. If I enlarge the below image on my computer the fence notches are very clear, but Iâm not certain theyâll be clear for everyone else so I circled them.
What is clear for everyone to see (if zoomed in) is the section of fence that forms the top wire âVâ. Thatâs the section thatâs directly in line with Trumpâs podium and window 3. Youâre off by one section of the fence. Where the fence notches are located, they donât line up with any of the windows or vents.
Thank you for these photos. And wow, this angle really shows how pronounce that AGR6 building sits in a depression. It adds further credibility of this seemingly very accurate drawing estimating heights. No window 3 shot could clear these bleachers, and maybe not even the fences either the one closest to the AGR but probably not the one closest to Trump. Look how high this fence is in relationship to the window (even weighing the nearness optical illusion). That building sits loooowwwwâŠ
Iâm able to zoom in the picture on my computer and the fence is crystal clear on my monitor. Once posted to here I canât see anything. Not being a computer guy is there anyway to share the photo as it appears on my monitor?
I tried that and I still canât see anything Iâm talking about concerning the fence. Makes me look like a nut but everything is really clear before I post it to here.
Yeah, you probably have more detail. I downloaded it and it gets pixelated when I zoom in. Still the window is below the top from that angle.
The pic I get is 1980 x 1280 256 KB size.
I for one believe he fired from even farther away, say lanes 16-17âŠmaybe even firing the last 3 shots while already starting to change position (which could explain 3 casings on the south half of the roof), then after #9 he moved to lane 20 and tried to take aim again. Lane 17 is the one that aligns with that passagewayâs edge. Afterall, there is video of him kind of moving, we do hear people saying âheâs coming this way, magsâ, and it explains why the distance from his body to the casings may look a bit short. @sherlock-holmes When I fire, the shells normally fly farther away than that body-shell distance from the photo. The direction is like what @bigtim mentioned alsoâŠ
If I could hit a target from 800m with a 5.56, you can hit a 200y with a 300 blackout. (edit: I canât hit 800 any day, mind you, it is difficult⊠but 200y should be ok for .300blackout)
Barrel lenght on ammo data is of concern. Longer barrels result in higher muzzle velocity, given the same round. Ammo data is published, ideally, alongside the testing details. On that spreadsheet I shared I just used a column to subtract percentage points from the calculated average velocity at a given distance, so I could manually mark ammo as a candidate or not. btw, I maintain my favouritism for the Hornady 75 grain BTHP T2 Tap Precision as a candidate (will post below some reasoning)
Iâm getting a vision from the future⊠a week will be used to get consensus on the math on how to create a bullet trajectory program (when we already have field tested calculators available that get people hits), then a month will be used by howdoiknow to come up with that program to convert the trajectory into lat/lon/elev data (assuming that actually happens). After this weâll be talking about elevations again, which we still donât have. After we do get the elevations, weâll see that both Crooks and HighRoof same very similar trajectories for 5.56 and both could be possible, but then the sound wouldnât match for HighRoof. Then howdoiknow will try to get ballistic data on a crazy ammount of calibers to find the one bullet that will give him the required average velocity at that distance, while still maintaining the required trajectory. But, we would be able to end the whole vent theory nonsense. Itâs a nice exercise for the mind, finding the bullet and the trajectory.
in the following picture, I have added a couple of lines:
the orange line is the line of fire from crooks to the JCB hydraulic lift that grazes over Trumpâs ear and can interact with the railing of the southern/right bleachers
the blue line is the line of fire from crooks should he have used lane 10-12 (roughly guestimated lane number)
the yellow line is the line of sight of the southern/right barn snipers. left of this line is obstructed by the trees, right of this line is viewable from their position
so, anywhere between the blue and the orange line would result in a line of fire from crooks that gets near to Trump and would end in the hydraulic liftâŠ
I use the hydraulic lift as a reference end point of the first bullet based on Mike Bellâs discussion and reconstruction of the first set of 3 bulletsâŠ
given that these are pictures taken from Trumpâs pole position, it is clear that, even if that flag is raised by about 2m to reach well above Trumpâs position, no bullets from any of these windows would have made it throughâŠ
@kincses-zsolt@howdoiknowthisinfo
Had a talk with AI about my favourite cartridge from that spreadsheet. First I got data from a ballistic calculator then I just asked ChatGPT what would the crack-thump time be from a mic 155 yards away. @greg_nNotice the numbers from that 75 grains cartridge⊠About the 7 ft distance, I plotted a line from Crooks-Comperatore and beyond⊠then got the distance from Trumpâs trajectory to that trajectory (image below). Thereâs also 70 grains version and another 77 that are great candidates also.
Crack-Thump Time Differences by Bullet and Distance
Hornady 75 grain BTHP T2 TAP Precision:
0 feet (direct at mic): 223 milliseconds
2 feet from mic: 221 milliseconds
7 feet from mic: 217 milliseconds
Hornady 62 grain TAP Barrier:
0 feet (direct at mic): 233 milliseconds
2 feet from mic: 231 milliseconds
7 feet from mic: 227 milliseconds
Each calculation takes into account the bulletâs speed at 155 yards and the respective delay caused by the sound traveling different distances to the microphone.
Below only the relevant parts, for brevity⊠@bigtim@sgt-raven Do you gentlemen agree he had a 3" sight height?.
I have this set of data that I would like to ask questions about.Drag Function: G1 Ballistic Coefficient: 0.355 Bullet Weight: 75 gr Initial Velocity: 2752 fps Sight Height : 3 in Shooting Angle: 0° Wind Speed: 9 mph Wind Angle: 90° Zero Range: 100 yd Chart Range: 500 yd Maximum Range: 5036 yd Step Size: 5 yd
** Corrected For Atmosphere** Adjusted BC: 0.38 Altitude: 0 ft Barometric Pressure: 29.92 Hg Temperature: 93° F Relative Humidity: 50% Speed of Sound: 1152 fps
Range Elevation Elevation Elevation Windage Windage Windage Time Energy Vel[x+y] (yd) (in) (MOA) (MIL) (in) (MOA) (MIL) (s) (ft.lbf) (ft/s) 0 -3.00 0.00 0.00 0.03 0.00 0.00 0.00 1261 2752
this is the line for 155 yards - 155 -0.65 0.40 0.12 1.98 1.22 0.35 0.18 954 2393. It gives 0.18 seconds of Time. This is the time from the muzzle to the trajectoryâs point at 155 yards, considering the zero sighted for the optic on the rifle.
Ok. considering this info, and that at the 155 yards distance there is a microphone recording ambient sound, and that we hear a crack-thump of the rifle being fired, how much distance would there be between the crack and the thump, in seconds (or hundreths or milliseconds). Please consider 2 alternate answers, one considering that the bullet passes 2 feet away from the microphone, and the other answer, as you choose best, with or without the mic-bullet distance at 155 yards.
### Assumptions:
** Rifle is 155 yards (465 feet) away from the microphone.*
** Speed of sound is 1152 fps.*
** Bullet speed at 155 yards is 2393 fps.*
** We are calculating the time delay based on two bullet-microphone distances: 2 feet and direct without distance consideration.*
Case 1: Bullet passing 2 feet from the microphone
Time for the bullet to reach 155 yards: Already given as 0.18 seconds.
Crack (bullet shockwave): The crack occurs almost instantaneously when the bullet passes 2 feet from the microphone, but sound still takes a tiny bit of time to cover the 2-foot distance. This time is:Timecrack=2 feet1152 fpsâ0.00174 seconds(â1.74 milliseconds).\text{Time}_{\text{crack}} = \frac{2 \text{ feet}}{1152 \text{ fps}} \approx 0.00174 \text{ seconds} (\approx 1.74 \text{ milliseconds}).Timecrackâ=1152 fps2 feetââ0.00174 seconds(â1.74 milliseconds).
Thump (rifle report): The time for the rifle report (thump) to reach the microphone is the distance from the rifle (465 feet) divided by the speed of sound (1152 fps):Timethump=465 feet1152 fpsâ0.403 seconds.\text{Time}_{\text{thump}} = \frac{465 \text{ feet}}{1152 \text{ fps}} \approx 0.403 \text{ seconds}.Timethumpâ=1152 fps465 feetââ0.403 seconds.
Case 1 (2 feet from mic): The time difference between the crack and thump is approximately 221 milliseconds.
Case 2 (ignoring mic distance): The time difference between the crack and thump is approximately 223 milliseconds.
What if the distance from mic to bullet was of 7 feet?
** The time difference between the crack (shockwave of the bullet passing the mic) and the thump (sound of the rifle report) would be approximately 217 milliseconds when the bullet is 7 feet away from the microphone.*
if youâre on MS Windows use the built in âSnipping Toolâ. Otherwise I can recommend âSnagitâ. Just zoom into the picture/video as much as you like, use above tools to make a cut out of the part you want, copy it and just paste it in here.
under the assumption that the shots were fired by crooksâŠ
I still find it amazing that the evidence photos of the fast buriers of information do not show any magazine(s), ammunition boxes, not even some food or a bottle of water or alike from the backpackâŠ
if crooks fired the 5 shots, I think he had only 5 rounds in the magazine: in his rapid fire mode, 5 shots were fired in under a second, then there was a pause of about 1 second before shot 9 came in and interrupted whatever he was doing on that roofâŠ
bullet 9 did not stop the rapid fire burst, as it had stopped already, and bullet 9 did not injure him significantly, as he was still more or less physically intact to sit upright on the roof, face the crowd to his right and point the rifle at themâŠ
and in my view of the following picture, the stock of his rifle is still intact while pointing it at the crowd, moments before swallowing bullet 10:
the damaged stock has very sharp edges and I would be very surprised if he kept these sharp edges so close to his face:
