Smoleńsk was a logical consequence of that risky culture in the highest Polish command. Initially, both opposing parties (PO and PiS) were so shocked that they basically cooperated in the investigation to find out what happened.

What happened next largely resembled Russian investigation into the #MH17 crash.
