Initially Lyuda, Semyon and Thibo may have had significant injuries. Kolevatov is said to have had a deformed neck, but it's not clear what that means? He may have been able to walk himself. Rustem although injured may also have been able to walk himself. That would leave Dyatlov, Zina, and the two yuris. Possibly kolevatov. If one person carries Thibo on his back, and another Lyuda and Semyon is supported and aided by two members of the group they could have moved slowly down the slope. Obviously there are possible variations on how they could have helped the injured down the slope.I prefer the narrative where the two Yuri's die first and clothes are removed later. There is evidence for this in that the bodies are rolled over sometime after death?
I do think that the so called fire orbs may be responsible for what happened that night. Ivanov may have seen additional supporting evidence.
My narrative is that Okishev supports the story that Ivanov showed his evidence to the Central Committee and they ordered a shutdown on the case. That can only be because they saw convincing evidence. It has to be photographs of fire orbs. There are missing cameras, missing film rolls....
One thing to consider is the size of these so called fire orbs. The witness statements describe them as "moon size". Some of these people were up to 70km from kholat syakhl. This would mean the fire orbs would have been around about 500 metres in diameter. Imo it's unlikely that the actual objects were that big, perhaps lighting up the surrounding snow/water vapour. "Light surrounded by a mist".
Personally I am not stuck on any particular theory at the moment. I am slowly exploring the options and the possible variables (of which there seem to be many). My favourite currently is still the military accident. infrasound is a possibility. I think murder is still a possibility, but it doesn't lend itself to the facts of the case. For instance Semyon left with his camera, someone the group had knives with them to cut trees. If they were forced out of the tent and marched down the slope to their deaths I would expect their attackers to have searched them and not allowed them to take knives with them. Also, I would expect none of them to have boots, or that they had different levels of clothing. The distribution of the bodies doesn't match what I would expect for a murder. There a few key facts that kind of make murder less likely.Rocket fuel would provide a good source of NO2, but there has to be some persistence to create a poisonous cloud that forces them to abandon the tent.
It must be true that whoever removed the clothing from the two Yur's knew or thought that Lyuda etc were still alive. It may have been the ravine four that took the clothes or just the remaining group members who were trying to keep them alive. The ravine four were better dressed than the others so even with the injuries they had a better chance against the cold and therefore they may have lived longer than the two Yuri's. There were some items of clothing found between the cedar tree and the ravine. The exact sequence of events still needs to be thrashed out. There are quite a few variables that need to be thought through carefully.
It's possible that the orange orbs were smaller and brighter and therefore appeared as a larger more diffuse light source. It would be interesting to understand the visibility conditions in the area that night.
“There were some items of clothing found between the cedar tree and the ravine”.
There are two reasons why clothing was thrown to the ravine:
The fire has stopped to work, probably because of the strong wind. The two Yuris froze. After that two possible situations may have involved:
1. The other four have taken their clothes in order to get dressed and at the same time to used the clothes to cover bottom of the den. But on the way to the den due to a wind condition and due to weakness and tiredness, they could not keep all the clothes in their hand, and it was drop down on the way.
2. The other four have taken their clothes in order to dress up and at the same time to used the clothes to cover bottom of the den, and they also disposed of some clothes along the way as a navigation as these three who went to the tent for things could later find them (because they (all group of seven) initially were separated at the fire).
