No more so than any casualty of extreme sports like climbing, biking, paragliding etc. It's cliche but I'd like to think the man died doing something he loved: piloting a home-made rocket. The world is a richer place for people like him following their passion.
uhhh.... i'm pretty sure we're going to find several orders of magnitude difference between 'extreme sports' (except maybe base jumping) and 'homemade rocketry'
