No, it happens all the time in Poland.
Can you provide links then Michal to back up what you say, admittedly I meant to say military air crash, but even civil air crashes are rare:
* LOT Polish Airlines Flight 007, crashed near Okęcie Airport in Warsaw. March 14, 1980
* LOT Polish Airlines Flight 5055, crashed in Kabacki Forest (Warsaw). Warsaw on May 9, 1987
* Lufthansa Flight 2904, crashed during landing on Okęcie Airport in Warsaw. Okęcie International Airport on September 14, 1993
And the last one was German!!
