Thanks for challenging my skills.

We need to use the average speed, and it depends on the distance.

This is the first five rounds from the list. The average speed between 130 and 170 yards. I will add the entire data table soon.

Unfortunatelly the problem is not linear. We need to know the average speed of the bullet, but it depends on the actual distance.
I have calculated it from 130 to 170 yards.

Let’s take first the simple case, when the projectile closely passed the mic, without Mach Angle.

We should know the speed of the sound.
Choose ammo.
Guess the distance and look up the average speed.
Calculate the time difference.
Increase or decrease the guessed distance and iterate the calculations.

howdoiknowthisinfo · September 10, 2024, 8:09pm

a couple of days ago, you showed a formula for the average speed for trajectory intervals of equal length. I cannot seem to find that formula again. could you copy/paste it once more?

many thanks!

Exactly great question I have also raised. If you’re standing in a DARK UNLIGHTED ROOM, and want to be concealed, during DAYLIGHT with a BIG OPEN WINDOW, you would NOT WANT NOR NEED A HEADLAMP to do this alleged window removal project.

There are hundreds of pixelizations and glitches in these images. Add that to reflections, and broken lapses in frame rates, etc. Conclusions you’re drawing are unsupported by real world evidence. They’re just pixels, compressed, uploaded, from already low quality source video. You have oddly glommed onto ones that fit your easily disproven narrative.

Too big, cumbersome, and slow for this type of a secretive operation. There are some areas in which humans excel, some in which machines excel. When I was deployed on my 4th tour, we had remove belt fed guns on top of our MRAPs. That was about 15 years ago. So yes that tech is available, far more advanced today.

But for a secretive operation where human engagement and precision is needed, decision making not relayed but on the spot, all perception senses employed, and the ability to rapidly escape undetected, is paramount then a remote gun would not work. Too much setup and tear down necessary, far to easy to be caught by someone not “read in” to the operation.

I don’t think a remote gun was used in the Trump attempt.

howdoiknowthisinfo · September 10, 2024, 8:33pm

me too do not think this sort of equipment was used, but he asked me whether such devices exist, and as they do, I provided him with the example of these devices and added the sidemark that it is impossible that this sort of things has been used, he…

A human sniper could far more easily climb into a small space with a low ceiling and lay prone. Snipers are rigorously trained to sit motionless in hostile climate environments for DAYS without detection. They often urinate on themselves while laying motionless. That ceiling area provides at least a few feet of clearance, more than enough for a human to crawl into and lay in wait, even in high temps. He could also wear a cooling vest (circulating or filled with cooled gel) to keep body temp lower.

The logistics of setting up and the height requirements of a gun mounted on a stabilizing tripod would be 10x or more difficulty. Plus a person OUTSIDE would not know nor have perception of the shooting area. Then there’s taking it down, and all manner of questions asked if someone unaffiliated saw this equipment during transport to and from, etc. And also, checking this out of arms room inventory would be yet another big red flag. It would just be much more difficult in my view.

Derivation:

average velocity = total pathlengt / total time

segment time = segment length / velocity at that segment

It reduces to sum multiplicative inverses when we use same length semgments. These segments must be so small the velocity change within to be negligible. (If not small enough, make them smaller.)

v~ = N/(∑(1/v))

Divide the total lengt into N segments. (I used 2 and half million.)
Calculate the speed at each segments (by polinomial).
Take 1/v, add tem up.
Divide N by the sum.

Do you grasp the concept that the Stewart video is taken from many angles laterally and height as he frantically points the camera all over the building. The “movement” you claim in the subject photos, is a still frame window but MOVEMENT of the person taking the video, giving it the OBVIOUS ILLUSION of window movement.

We can clearly see the window is fixed in place and not moving, not opening, nor being removed due to there being tape around the perimeter and window reflections. It is there in every single picture you’ve posted. Furthermore, there is simply insufficient TIME for someone to remove the window, fire a rifle at a distant target with aimed precision, and replace the window, undetected, even with help. Furthermore, the Stewart videos are helpful but of a low pixel quality. Just look at these images. There’s nary a straight line and all manner of broken planes and pixelization.

The excellent images provided generously by @rough_country_gypsy are taken with high quality static video/photo equipment from a stationary drone, at a much closer and focused position.

While I do find the entire 3 extra shell casings suspect, as long as they were to his right side and 120 degrees forward, lateral, or rearward there’s not much inconsistent about that from an AR15.

As for the ones on the opposite downward slow side, I could visualize them hitting the flat cap, and carrying forward movement and bouncing over to the opposite side. They are just hollow pieces of brass being thrown with some spin and authority, bouncing off a steel roof which probably has some spring (as opposed to landing in mud or sand where they would not bounce or travel).

This could be replicated pretty easily, with just some suspended sheet metal and throwing brass casings to observe behaviors.

Any brass to his left to too far away, of course would be highly suspect.

I have found these:

howdoiknowthisinfo · September 10, 2024, 9:16pm

my program outputs this sort of stuff:

the range and vertical drop and windage inches are basically (x,y,z)-like offsets which I translate in (lon, lat, alt)-coordinates in my kml files

so, I will add the average velocity N/sum(1/v) for each line.

if you provide me with the coordinates of the different microphones you want to see whatever formula calculated for, I can easily add it and enumerate it for the various ballistic parameters…

Setting zero at 300 yds is kind of silly for such a slow moving heavy bullet. Using 100 yd zero, will result in +1.5" at 50 yds. 75 yds will be less than 1.5", not 7". As Sgt correctly pointed out, there will be two zeros, one on the way up (due to offset angle), second on the way down. Subsonic 300/308 high grain bullets are at best a 200 yd bullet. I have my 300 BO zeroed at 50 yds. 100 yds is still close enough to not worry about POI. I haven’t even attempted shooting out to 200 yds with 300BO, it will have a significant amount of drop.

Nearly all the brass ends up left of and well forward of the muzzle on the line of fire.
Look carefully at the full size image again

Interesting test. A lot of the shots look quite a bit like shot 4 at first glance and yet the correlation isn’t that high.

He should throw that gun away and buy an old POS rifle like Crooks’ and some Federal ammo, that will make exactly the same report every time.

So, controlled test doesn’t correlate well.

Audio source 4 correlates horribly between shots, particularly between shots 1-3 an 4-8.

Police cruiser channel two won’t correlate with channels 1 and 3.

But each of channels 1-3 in police cruiser has basically perfect correlation where echoes don’t overlap reports, and near perfect where they do.

Seems normal.

I concur. Plus, we don’t know the “exact” position of the rifle’s receiver in relation to the ridge cap. I was going to test this (shooting from a metal peaked roof with an AR) but there are so many variables from AR to AR it most likely would prove nothing.

bigtim · September 10, 2024, 11:01pm

I think we can make an educated guess. His target is almost level, a bit lower than him. He’s laying on a slight incline. He had to clear the ridgecap of course. And a rational person would not go higher than necessary. So as I mentioned in another post, not much more than his rifle barrel likely above the ridgecap. That would expose his barrel, optic, upper 10% of his rifle including stock, shoulders, and everything above his nose.

rough_country_gypsy · September 10, 2024, 11:17pm

A rational person wouldn’t have been on the roof in the first place let alone run the entire length of the building from North to South so everyone could see and hear him. I’m betting he was higher on the ridge cap than most people suspect for the first 3 shots.
