Well here it is this guy claims to have built his own jetpack, see for yourself

"Claims"? :-?
I think his claim is pretty well-substantiated...

It's really just a jet-powered hang glider; when I read "jet pack" I thought you meant the wingless VTOL type.
But this thing is even cooler...! 8-)
But he should have struck more gnarly "hood ornament" poses for the camera...

And that Moby song... yawn...
Still, it's a fantastic little flying machine!!
Thanks for the link!
