Well, one man in Switzerland took this dream more seriously then I did, and built himself his own jet-pack; it not quite Rocket-man, but its one step closer.
His foreign language website is here.
There are some good youtube videos of him here and here.
On an off note; this is one of the reasons I love economic freedom, it allows people to explore avenues that, in poorer or more controlled countries, will not be explored. Does China or Venezuela produce many Jet-Men? For that matter, do they produce many Bill Gates or Steve Jobs?
No, they don’t.
Free-markets help set these quirky geniuses lose, thats part of why I support them; if only in the hope that I can fulfill my dream of owning my own Jet-Pack one day.
