Today I did a daytrip to RJK on a HLX 737-700. Before we landed, we encountered extreme turbulence. I know that pilots have another definition of "dangerous" turbulence than ordinary passengers like me, but obviously even the flight crew found it rather bad, as they said in the evening ("There are 4 passengers onboard that came with us here in the morning, and I could understand if they chose never to fly again... But turbulence will be less severe now").
I read that a Tu134 crashed there in the 70s. These fall winds (boras) obviously can get very strong.
My question is, how dangerous are they? Obviously we landed safely and the flight crew certainly wouldn't even have tried if it was dangerous, but is turbulence an issue in Croatia?
