It was not sufficient to prevent the partial destruction of the aircraft. By any definition, that is a crash. (And happens to be a crash by the official definition, too.)
Actually I like the way they put it : "Aircraft damaged beyond economic repair"
WojtekSz, if you're ready to invest some money, go and hire a flight instructor in Warsaw who could demonstrate what it's all about. A Cessna will do just fine and pick up a windy day, result will be only more telling.
