TOG Posted October 8, 2022 Share Posted October 8, 2022 Also it looks like the railing on the far side of rail bridge is missing. Similarly there was some comparison of satelite images before and after the strike and it looked like on some part the bridge got narrower. The truck bomb was unlikely to do this. The rail cars don't Look like they exploded. It is next to burning rail car so maybe it is cased by heat. 0 Quote Link to comment Share on other sites More sharing options...

Just in the CCTV room from what we could see there were at least 18 cameras on the bridge. To not have any glimpse of anything is possible but doesn't seem probable. Then looking at the 20 defense initiatives to protect the bridge you would think there would be something somewhere that would have detected an incoming missile. There's still no video evidence of Hrim-2, or anything else for that matter, having hit Saki. It was also covered by multiple air defense systems that didn't react to not one but FOUR missiles. No new information since then and that was months ago. So that's not a reason to discount Hrim-2 here. Steve 0 Quote Link to comment Share on other sites More sharing options...

However although I'm liking all the theories of what did it, everyone has overlooked the main reason for all major russian mishaps in this war. The extremely dangerous and explody act of smoking. The smokers done it again, dropped his fag in the truck, rolled under the seat, set fire to highly flammable cheap chinese foam padding which then caused 152mm ammo to explode and blew up the bridge. Case solved, call me Sherlock not Shirley. So the whole problem with the Russian debacle is the fault of Philip Morris and RJR. 0 Quote Link to comment Share on other sites More sharing options...

In Saky, the strike was proceeded by a HARM campaign which would explain it. But here, I don't think that happened. Unless they specifically picked this part of the bridge because of AD blindspot or something - I think there were reports of Ukraine drones "probing" Crimea. Unless the Russian AD is just terrible against ballistic missiles. Do we have any data on how it deals with e.g. Tochka-U or how it deals with similar missiles in Ukrainian hands? I hear about lot of interceptions but I don't know how much is cruise missiles and how much is ballistic. 0 Quote Link to comment Share on other sites More sharing options...

Best place to get current info, reasonable opinions, experts on details etc. Helped me calm down in stressful beginning of this war and pass hope to some friends. First time I managed to find something of interest, some of you may have seen it but I think it was not posted. The second video shows explosion in slow motion. Looks fake to me. How is a surveilance camera able to capture a detonation of explosives in slow motion? It happens extremely fast. How many FPS is that camera running? And even if it did run super-high FPS, it wouldn't just capture a general glare - it would show a smaller fireball at the point of detonation, just before it expanded... 0 Quote Link to comment Share on other sites More sharing options...

Battlefront.com Posted October 8, 2022 Share Posted October 8, 2022 2 hours ago, Haiduk said: Hrim-2 is ballistic missile, it have to attack from the top, but here we've seen something exploded slightly aside and under the bridge, like cruise missile. Also one woman from the village near Kerch, wrote she drunk a coffee at 6:00 and as if seen two missiles, which flew on very low altitude. If this is not a fib, that this could be cruise missles atatck and... what air defense doing? The arguments against a cruise missile are the same here as they were at Saki. Range would require a remote launch from see, well within Russian controlled waters, the warheads aren't all that big, and it would be very difficult to hit thin vertical surfaces (piers). The visual evidence also shows evidence of a top hit. I'm confident enough to rule out cruise missile. Steve 0 Quote Link to comment Share on other sites More sharing options...
Bulletpoint Posted October 8, 2022 Share Posted October 8, 2022 Another way of looking at it is to ask - where would that general glare be coming from? If it's from an explosion that takes place in the air above the bridge, the point source would be visible, not just a general glare. If it's below the bridge, the light would not be visible at all, because the bridge would block it. The only way it would make sense would be for the source of the explosion to be in the air above the bridge, but so high that it would be outside the frame. And then the explosion would need to be absolutely enormous to destroy the bridge. 0 Quote Link to comment Share on other sites More sharing options...
Battlefront.com Posted October 8, 2022 Share Posted October 8, 2022 Truck bomb theory... as I stated a few pages ago, I think it is very unlikely for a lot of reasons. However, if Russia did it themselves as a false flag attack then many of the logistical issues go away. HOWEVER, I don't think they'd do it. It puts the entire war effort into a death spiral. No, they would do something like blow up a government building in Sevastopol or something else like that. The point of a false flag attack is to lay blame on your enemy in order to gain more room for action. Russia doesn't really need to do this for any particular reason. They're already at war with Ukraine and they are beyond the ability of getting world opinion to shift against Ukraine. If they are looking for some sort of excuse to use a tac nuke, for example, they would just do it. Steve 0 Quote Link to comment Share on other sites More sharing options...

The full version had the first sign of flash as just a partial bar at the bottom of the screen (camera refresh artifact), but that is cropped out here. I'm thinking this is just more of an artifact of how the image updates or something. There is no way the initial explosion was out of the frame there.

The original shows the bottom ~20% of the lines in the frame saturated when the explosion starts. It's entirely possible for the truck to be intact in the first half of the frame scan (and show that way in the frame) while it's turned into very small parts as the last 20% of the frame is read out. The frame rate and shutter speed aren't terrible for a night-video - the motion is pretty smooth and objects aren't rippled from the line scan. It could be as high as 15 fps - we could work it out backward if someone knows the speed limit on the bridge and the road dashed line marking standards. If we call it 10 fps then there's at least ~120 ms (maybe 220 ms?) where the camera is totally saturated in the original video before the fireball diminishes. And it's complicated by aliasing with the frame rate and compression of the phone used to record the video from the computer monitor. 0 Quote Link to comment Share on other sites More sharing options...

We manually adjust the camera's framerate to visually match CCTV, so we go to 15 fps (very choppy, gas station/pawn shop type) or 20fps (smooth, but still less than the classic 24fps of film). But proper modern, high grade CCTV can now be 36-48fps. It just comes down to storage capacity and priorities. I do know that some large scale national infrastructure in Europe has some good CCTV quality. I don't view that video mentioned above as fake. .

It's got to have a lot of compression to do that - I take a lot of incompressible video data at 2kx2kx8 bit x 15 fps and that uses half of a GigE pipe for one monochrome camera and spinning drives can't generally keep up with sustained recording - we have to use SSDs to avoid losing frames. The video looking along the bridge very well could be higher than 10 fps frame rate - the frame to frame motion is pretty small for the vehicles, and the resolution is pretty chunky. 0 Quote Link to comment Share on other sites More sharing options...

A single explosion at the road surface, in the middle of a span? That shouldnt push the whole span sidewayss, off its pinning. It should just rip a lot of steel apart and fracture/break the rebar support beams. To push the whole span sideways requires an enormous amount of force, and needs to come from a direction non-perpendicular to the surface. A blast favouring one side of the span (eg above one lane as you mention) might do it. But it's a big ask... 0 Quote Link to comment Share on other sites More sharing options...

I can't imagine HDDs keeping up with modern data throughputs of 2k, even at 15ps, for a usefully reliable timeframe. I'm curious what you mean by "incompressible" video. All digital video is fundamentally compressible so are you operating according to external, end user delivery requirements/parameters? Don't want to come across as snarky, just genuinely interested.
