Russian authorities have given their verdict, now it is Poland’s turn.
Warsaw claims Russian ground controllers made mistakes in the build-up to a plane crash that killed President Lech Kaczynski and 95 other Polish figures in western Russia last April.
This after a Russian report said the Polish crew made mistakes, and was too scared to abort a landing in bad weather because it would have angered the president.
But Poland today released transcripts of conversations between Russian ground controllers at the Smolensk airport.
It accuses them of making a series of mistakes and not sufficiently supporting the Polish crew attempting to land.
They also allege that controllers gave wrong weather and visibility information, failed to close the airport despite thick fog and confirmed the Polish plane was on the right track to land while it was too low.
Warsaw says the airport was also badly equipped.
