Here it is, some 40 years later and there is no safe personal jet packs available on the open market that you can use to commute to work. But it looks like there are some serious enthusiast out there. Check out this report from the second annual Rocketbelt Convention. Cool stuff. I love the last line: "... paraphrasing the words of the great Stephen Colbert: For years we’ve been promised little wrist-sized televisions, a meal in a pill and jetpacks —- let’s hope this year that promise finally becomes a reality."
