The head of the society of cable car operators in Austria says yesterday: "In my view is the closing of cable cars during transportation flights absolutely unconceivable".
"It's up to the helicopter operator and the authorities, they have to find safe ways".
"Wash my skin, but doesn't make me wet!" I would say.
Construction and service of cable cars in high mountain area are impossible without helicopters and their transportation flights.
And to the banner, yes in my mind it's also an external load operation. No question, such a banner isn't a bomb like the concrete kettle. But a few hundred pounds coming from the sky are allways dangerous.
But i'm shure the flight is allowed and in law, like the tragedy flight in Austria.
