There's lots of details missing in the autopsies from a blast wave.
Of course. What are you expecting from the autopsy reports that were produced by Lev Ivanov at Sverdlovsk Prosecutor's office? The reports for Dubinina, Zolotarev, Thibo, and Kolevatov were printed on the same typewriter, on which Ivanov printed Closing statement for the criminal case. AI doesn't tell you about that, does it? To rely on AI advices is even worse than to rely on the tale, which case files tell you. The autopsy reports do not have a single attribute that suggests they had ever been at the Sverdlovsk medical lab. The reports are confirmed only with Vozrozhdenniy's signature on their last pages, the rest of the pages is just plain text not authorised in any way.
lie on their traumas exactly.
Depends on which AI and how you use AI ?. I don't think there's any confirmed evidence that it's the same typewriter, this is speculation with little evidence. The autopsy show no signs of blast injuries, the landscape shows no sign of a blast , your diagram of overpressure of buildings is a standard illustration used in fire instruction and many other instance's. You have got to look at what happens to a human body in a blast wave and it needs to be stronger blast than your low level blast example .
The rib fractures are consistent with a compression not a blast.
The ribs and the skull fractures are consistent with the traumatic mechanism suggested by Vozrozhdenniy - strong gust of wind throwing people on the rocks.
Strong gust of wind = blast air wave
Rocks = rocks at the bottom of the creek polished by water
All three affected hikes lie on their traumas exactly.
A strong gust of wind is not the same as a blast air wave , we might as well just say a a blast of wind blew them off the ledge of the ravine or the fell into the ravine . However, and I will repeat , there are no signs of blast injuries in the autopsies and the environment that would have been observed or reported .
The rib fractures are quite specific and reflect compression .
