Very cool!!!
As I understand it, the big problem they are working right now is flight time. From an earlier publicity round, focused much differently than the one you can see presently on the website:
Martin says that he hopes people will also use his jetpack for recreation. He’s designing it to meet FAA ultralight standards, which will limit the speed to 63 mph and flight time to around 30 minutes.
I haven't read where they've reached 30 minutes flight time yet (or their original 45 minute research goal). They'll need MUCH more than that to perform the missions they're aiming at in the current publicity round. Right now, they are looking for investors. Go in w/ 'open eyes' - sounds like they have a long way to go, but it would be GREAT if they make it.
Regards to all,
