No mention of them so far. If they parked themselves, I'd like to know what the leading edges look like. I've seen the blades on the ground up in Gainesville, Texas, at a trans-shipment storage facility along Interstate-35. They're extremely thick epoxy-composite. I can't imagine that 'any' hailstone, regardless of size could 'touch' them. Don't know.
The turbines at Jacksboro, Texas, that went through the tornado did nothing to the turbines there. Often, the height of the supercells that spawn tornadoes, also produce hail ( it's a hundred below zero F up there ).
