What I found extremely "sad" ( in absense of a better word) is that The polish Air Force , once one of the best, has fallen so low in Safety standards and most importantly never learns apparently.
The very similar crash of one of their Casa C295s in January 2008 should have started to rings bells. What it did was the dismissal of a few guys, and continue business as usual. see here ( despite the misleading title ) :

Blame individuals to hide systemic failures . As old as the world. Not learning from past experiences and they will resurface and bite you.
The "ironic " bit of that C295 accident is that the Top Polish Air Force brass on board was going to attend a "Safety conference " . I guess the conference was cancelled and never took place again.
