I don't know what you are talking about.
On the Polish TU-154M's, there were several data/voice recorders. One of them, the ATM-QAR/R128ENC, was a specific Polish creation, created originally by LOT engineers in 1989 who felt that the other recorders of the day didn't do a good enough job. It was partially motivated by the IL-62M crashes in 1980 and 1987, as they wanted to make sure that they had their own sources of data. It was also intended to monitor the engines of Polish planes, as this had been a significant issue after both LOT crashes. In fact, this sort of recording was ahead of its time, as it only became standard in the mid 2000's on passenger jets.
So, on the flight in question, this box was installed. The company responsible for making them, ATM, were the only ones that could decode the data. So, the box was taken to Warsaw a few days after the crash, and the contents were copied and examined by Polish experts on Polish soil. This is the box that collaborates the data recorders that were read in Moscow.
If you don't know what I'm talking about, how can you even begin to talk about the crash?
Totalitarian communism got imprinted into you for ever.
He cannot imagine a Poland being anything other than under communism. For him, keeping people stupid and uneducated is the correct path, because then they won't challenge the system.
