A few years back a friend of a friend's 2nd cousin reportedly returned to the Carson Valley with lots of extra altitude and so flew north up the spine of the Carson Range (east side of Lake Tahoe) to enjoy the view of the lake. He saw an orange spot on a rock outcropping far ahead on the rim trail near Genoa Peak, so pushed over to have a closer look. He flew by the hikers doing close to VNE (146 knots) and pulled up into a chandelle for a return pass. I'm told he got no closer than maybe 100 feet. Now below ridge, but with lots of speed, he easily pulled up to clear the ridge and head home. All the while thinking to himself how cool it would be to be on the ground like that to see a spectacular high speed pass - - glider makes a sound like a jet aircraft but without the engine noise.
Next morning he gets a call from a friend working at the local glider FBO. Friend tells him, "There's someone here who wants to talk to you!". He is now really worried. Friend puts a Belgium fellow on the phone who says he and girlfriend were on the rock outcrop. Hapless glider pilot asks him if he's upset. Belgium fellow (who turns out to be a power pilot) says, "Oh no! The lake, the trees, the clouds, the sky! You were the ICING!!"
In the OP video, that was way too close. I can see coming over a ridge and getting really close to people you don't expect to be there. But today, with cell phone video so prevalent, strafing strangers is just asking for FAA trouble. That said, I'd love to be straffed like that.
