Sad news, and my condolences.
I watch them practicing up and down the runway at my home airfield on the weekends, with the instructor chasing them down the runway in his / her car. They look fantastic fun, but the negative G thing puts me off....but this is the same with helicopters like the R22 as well, so I don't know how much of an issue it really is.
I *believe* that 2 seater variants are pretty dangerous, something to do with the rotorheads??? (which is why when they are learning the instructor chases them down the runway in the car).
Fate is the hunter, for what it is worth, at least the person in this sad event died doing something they enjoyed, rather than of terminal cancer or some other pointless way......
