Wow! I guess necessity truly is the Mother of invention. I had a similar situation while helping to develop a Ice Boat utilizing windsurfing sails. I got bounced out of the cockpit on rough ice at 50 miles per hour and realized immediately, we needed to incorporate seat belts.

- One must admire the tenacity of mankind. When watching a man get tossed from an ice boat at 50 MPH or watching another man get tossed to his death the thought is "Must invent way to secure pink flesh to vehicle", not "I won't do that again". Wasn't the helmet invented the same way?
