I think we are all reading to much into the why and wherefores regarding this incident.
I have been thinking about the incident and it goes like this.
The group apart from 2 others Dubinina and Dyatlov were Grade 3 hikers. So apart from maybe geological tasks, they were there to accomplish . (their Grade3. Now I know they were all accomplished hikers but somewhere along the track they fell into a trap.
It is generally assumed they fled in panic at the time, but these footprints suggest an orderly approach.
So maybe the tent just tore open from its many repairs or was just ready for take off ( I remember in my youth my father had made a tent for 8 people around the same year maybe 58 and we went camping on a beach and at the end off the school holidays in 1959 with sunshine all the way a ferocious storm was brewing, the old man took us to someone holidaying in a caravan for safety, we were 3kids 7-8-12. Anyhow along came the storm and away went the tent spinning on its side going out to sea, never saw it again.)
So the tent splits open from the weather, but instead of staying with the tent they decide to go down to the treeline for cover as in the orderly footsteps that are seen. Unfortunately with the goods they were trying to take with them there were many accidents resulting in a few cracked ribs a head fracture and many cuts and bruises on the hands from the snow-on-slate situation until they reached the treeline, battered and bruised Dyatlov gives some orders. But wait one of the group is not there so 3 of the group including Dylatov head back for the tent not realizing the missing person has circumvented them and arrived back with the others who are making a fire, the 3 succumb to the cold.Back at the tree a few of them climb to see if they can see the 3 ,to no avail. The fire has gone out due to a lack of fuel. 2 stay with the cedar whilst the remaining 4 go off in search of fuel but end up in a creek which adds to their demise. The 2 at the cedar succumb to the cold.-------- conclusion pitch black,bad luck and freezing temperature with an unusualy fierce wind.---- No trees No aliens No wild animals No military experiments etc etc etc.
