Poland has published cockpit conversations of the last dramatic minutes before the April plane crash that killed Polish President Lech Kaczynski, revealing that pilots screamed and cursed after hitting a tree.

The recording shows that 16 minutes before the crash, the control tower in Smolensk, Russia, told the Polish pilots that heavy fog had created bad landing conditions. The pilots said they would give it a try anyway.

The Interior Ministry published the 40-page transcript on its website a day after Russian handed over copies of the documents to Polish officials.
