The point I made was that he flew with an underslung load over an occupied cable car. You cannot carry a load by crane over traffic nor over a train. At the very least you have to wait until the traffic has passed. The helicopter could have crossed behind the gondola. This would have presented a smaller target at the very least. This thread has demonstrated that underslung loads do slip more often than we would like. They certainly used to from cranes. We had many fatalities in the sixties on site. The consequence was the Health and Safety At Work Act 1974. Nowadays we rarely have anyone hurt due to a strop failure or similar in cranework.
Austrian H&S is as strong as any in the world.
