From the linked article: "This [crashed] aircraft was intended to be the production version of the "Stratos" aircraft. The prototype version had successfully flown some 340 hours. The production model incorporated significant changes made by the designer/pilot."
If anyone wants a crashed belite in the PNW area, let me know.
Test-flying unconventional prototype / experimental airplanes, or flying commercially available ultralights? With or without training?
And wingsuits – proximity flying? base jumping? Or just jumping out of a plane?
The risks of those scenarios are magnitudes apart.
Personal aircraft are about as dangerous as motorbikes. Base jumping on the other hand, whether with a wingsuit or not, is one of the most dangerous recreational activities you can do, with a fatality rate of something like 1% per participant per year.
