RegDep,
I read at Echo of Moscow site that MAK report is a summary, and to accompany it there are 64 tomes o
of gathered material, interviews, records, tests, various papers. That will become food for criminal (law) investigation cases, opened in both Russia and in Poland (separately in each country), because of death of people.
So, one would expect, a lot of more things will surface up later on. At the moment the bargaining goes only about what of it should have been included into the MAK (aviation) summary as meaningful.
