The WSL Institute for Snow and Avalanche Rescue was testing rockfall barriers in Flüela Pass, Switzerland by releasing large objects attached to helicopters above the nets.
The result is some serious mountain destruction, and a surprisingly effective rockfall barrier.
They could use some rockfall barriers like this in Morgantown, WV.
I read about at least 10 cars getting smashed by falling boulders in the four years I was in school there! 😆
Vide description translated from German to English:
“The WSL Institute for Snow and Avalanche Research SLF and Geobrugg AG have conducted tests on the Flüela Pass over the past two years to find out how realistic impacts from test blocks affect rockfall barriers.”
