Hello everyone, this is my first post here but I did read all the post published so far.
Today, Apr/18, part of the flight recorders content has been revealed by the Polish investigators. The article is here (in Polish, my native language) but it's still sort of vague:
Krzyk cierpienia. Zapis czarnej skrzynki - Katastrofa w Smole?sku - Dziennik.pl
What surprises me is the statement about the voices and noises coming from the passenger cabins. Investigators say that several (which in Polish means definitely more that 20) last seconds of the recording contains increased noises and loud voices (followed by the screams of pain) of the passengers, as they already knew about the inevitable tragedy.
This does not make sense to me as all the drawing posted here suggested the the time between the first tree hit and the crash was definitely less than 10 seconds (or the distance of ~700m at the speed of 200-300 km/h).
Moreover, all what has been discussed here suggests that 30 seconds before the crash the crew did not know they were flying too low.
I am barely bringing more, hopefully reliable, facts. What do you think about them?
