I'm the first to salute a bit of Kiwi innovation and I take my hat off to the man. However, the pitch to the world relies on everything operating peachily. I suspect (proportionally) very few Harrier jump-jet pilots will buy one of these things. Those that do, will need to know that there is a reasonable chance that this could hurt, maim or kill them. The fact that the ballistic recovery 'chute only protects the user above 100 feet is a worry. The reaction at Oshkosk seems lukewarm and understandably so. The timing might have been forced by the need for sales but if the 4 foot hover restriction could be relaxed anywhere elsewhere, it would sell itself. I'd love to see it hundreds of feet up at 100 km/hr. Hopefully we will. But.....
Not sure that thermals would be a major factor given the small ducted fan size relative to the weight (effectively a high wing loading) the issue of getting majorily out of the perpendicular could however be quite serious and may require something like a drogue chute to be deployed to reattain the correct attitude. I think it is an interesting concept and would like to see it attain a degree of success but I think there are alot of safety issues and subsequent redesign required before it could be sold commercially, even then I think it will never be as safe as a conventional aircraft (not even an R22 ) , I can imagine CAA putting severe operating restrictions on such a craft (like not operating anywhere near a built-up area)

The Martin Jetpack is to be manufactured with an emergency parachute system. The makers of whole-aircraft recovery systems, Ballistic Recovery Systems, announced this week that they have entered into an agreement with Martin Aircraft Co. to provide emergency ballistic parachute recovery units for all production Jetpacks. BRS say that their system will open and function properly at relatively low altitudes particularly if the craft has some forward speed at the time of the emergency.
I am still not sure that I would want to fly a Jetpack however.

"Where's My Jet Pack? It's In San Carlos ...
Saturday at the Hiller Aviation Museum's Jet Pack Show in San Carlos, Calif., scientists, inventors and pilots taught visitors about research and progress in the field of modern jet packs. Organizers claim the event was the largest collection of jet packs ever assembled in one place for display. Modern players like Jet Pack International, Thunderbolt Aerosystems, and Solotrek mixed with research experts that included former Bell president Hugh Neeson. The recently famous Martin JetPack, which flies on two ducted fans powered by a single engine and was publicly debuted at AirVenture Oshkosh this year, was not in attendance. Flight times for current jet packs are most often counted in seconds, but Jet Pack International is one company offering a model that it says can fly for 9 minutes and can be had for $200,000 (flight training included). If you want to stay aloft for longer periods of time, you'll have to wait for technology to catch up with your desires. A 20-second 130-decibel demonstration flight made an instant celebrity of pilot Eric Scott who has already acquired the experience of some 700 flights over 16 years. Jet Pack International may be hoping for more celebrity -- the company has been working on a reality television show based on its search for new pilots."
USD200,000 for a 9 minute endurance doesn't really cut it somehow.

I heard that a Martin Jetpack is on static display at 'The Cloud' during the week (but not in the weekends. I've never seen one in the flesh, so popped in this afternoon.
There it is, quite a large and heavy-looking beast:
I still don't believe that it will walk the talk, but you never know. They are obviously trawling for further monetary investment in the project. One Martin Aircraft P11 Jetpack has been registered ZK-JME/2
There is also a promo video of NZ innovation being shown on the large screens. Included in this video is some obviously CGI-generated Jetpacks zooming around Queens Wharf.

Retirement is something for the young. Once you are old you never seem to have the time.
I'd like to try it, but I'd like to try it untethered and outside. In fact I would like to see it untethered, outside and manned in flight at least 100ft up. In my opinion it was silly to show it off at Oshkosh before they'd done the altitude test, but that's just me.

Having seen the video there of their new version, which has been completely redesigned, it shows a lot more promise indeed. They begin test flying with a human soon, but the remote control tests look pretty good. I wish them the best of luck.
