Turbulence from departing UH-60 flips landing SR20
More than 25 seconds after a departing Blackhawk Sikorsky UH-60 takes off from Runway 33 in Fort Collins, Colorado, a student pilot attempted to land a Cirrus SR20 and was tossed like a rag doll after descending through the massive rotor downwash.

If I'm reading the weather report correctly, the wind was coming probably from ESE, and the runway is about SSE, so the wind would have been blowing mostly down the runway but slightly away from the viewer. But that's probably negligible compared to the random nature of the turbulence.
Old story but didn't a private jet crash in KSNA after taking off too soon after a 757?
A Westwind following a 757 back in 1993. A year or so later, the 757 was included in wake turbulence rules, like heavy aircraft.

Another link included on that page describes the results of the lawsuits, which basically called the Westwind pilots out for not handling the situation well.

I was on a 747 a number of years ago, about 10 minutes out from Narita when we went through someone's wake -- the plane rolled left about 40 degrees, then right 40 degrees, then stable again. There was a little up and down with each turn. In a 747!
Last October, same thing on the way in to Heathrow one morning in an A320, also in the maneuvering phase about 10,000 ft. A strong bump, certainly different than one created by the atmosphere itself. After landing, the captain actually announced that we had gone through the wake of the A380 ahead of us.

frightening, and hopeful the pilot makes a good recovery. Looks like something out of a movie
The wind would be going the opposite direction from the helicopter and to each side for the most part. You can tell from the dust of the crash that there is a tail wind. That would counteract the motion of the helicopter's turbulence, causing the donut shape to expand forward but not back, so the rear part of the donut would be rolling in place until it dissipated.
From looking at the dust, the tail wind seems to be parallel to the runway, so it seems odd that the right wing seems to be lifted preferentially. I'd expect instead, to see something more akin to ground-effect, lifting the plane as it enters the donut. Then it would descend again as it crossed to the other side of the donut. Instead, though, it looks like the right wing got the worst of the turbulence. So maybe the wind was actually a bit diagonal to the runway.
