Flying on plane, mountain biking, being on a boat, motorcycle are nowhere near being on a homemade submersible with a $250,000 ticket price. They died, whoop de do...and their families, etc? Outside of committing certain crimes and the like, I feel sympathy for anyone getting grievously injured or dying while pursuing something exciting. Now would I have gone on that vehicle???? No... But cars, airplanes, motorcycles, boats, mountainbiking....there are many 'questionable things' to do for fun that may kill you, rich or poor.
