Jet Pack Company Executive Crashes During A Test Flight (kdvr.com)
The Vice President of Jet Pack International was hospitalized Friday after crashing during a test flight in Denver, according to the Associated Press. Though he's successfully flown the company's hydrogen peroxide-fueled jet pack more than 400 times, Friday the vice president experienced "control issues" while hovering 20 feet over the "Go Fast" energy drink company while testing some adjustments, and ultimately crashed in a nearby industrial park. He fell on his head, and he wasn't wearing a helmet, but after receiving 27 stitches, he was released from the hospital Saturday afternoon. The company's jet pack normally has a range of about one-quarter of a mile (and reaches heights of 100 feet) with a flying time of 32 seconds, the Associated Press reports, adding that "The FAA is investigating the crash."
Helmets aren't especially useful and at least some research say, they increase risk to the bicyclist's health.
Given how much more fun it is to ride without one, you may want to reconsider — unless you wear it all the time, even when walking. Just in case a car hits you...
Dunno about jetpacks, but bicycles just aren't fast enough for helmets to perceptibly increase one's chances in a rare accident to justify constantly incurring costs in comfort and situation-awareness during the rest of your riding. Yes, there are statistics showing correlation between fatalities and riding without helmet, but that does not prove causation.
Surely, everyone is entitled to making their own choices, and I'm not going to force anyone to ride without the protection they want. I just want the same freedom for myself.
In Soviet Washington the swamp drains you.
This type of system dates back to the 70s. it inspired countless engineers, but has a long history of accidents.
the time aloft is so short that there isn't room for the slightest hesitation before you run out of fuel and become a falling brick.
it was ok for Hollywood where you filmed a series of 10 second sets and spliced them together, but it was never practical for any other use.
Companies with newer designs have increased the time aloft and in doing so the safety.

Martin Aircraft even uses a ballistic recovery parachute for added safety.

people need to apply a little darwinism and start supporting the companies with the safer systems.
