Maybe the Cessna pilot was IFR?
Whatever, he has some ‘sp;ainin to do with the Austrian version of the FAA.....
“The sightseeing plane, piloted by a 28-year-old man, was able to land safely at Zell am See Airport, officials said.
He claimed that there was no way he could have avoided the paraglider.”
Being IFR doesn't excuse violating "See and Avoid" when you're VMC. Regardless, and he violated the paraglider's right-of-way (unpowered has right-of-way over all else).
