Martin Jetpack flight demonstration April 2009

mythbusters cant do this. :)

The Martin Jetpack is expected to be available for public flights from mid 2010 -in Christchurch, New Zealand.

if i could just ride this for 5 minutes my life would be complete. when will this be available for purchase? I'm guessing when I am about 60 or 70 IF I could even afford it haha.

Does it matter how high it can go now it is all about going as high as u can and people will keep on trying now obviously they have there thrust and and can sustain lift and hover they just need to work on a way to allow for sustained flight without relying heavily on there thrust if they figure that out they would be able go higher and fly with more control this is just a prototype and all I have to say is GOOD LUCK to MartinJetPack.

... yes, because all aircraft ever designed jump from working prototype to final production model in less than 2 years, spending no money on development costs during that time.
(that was sarcasm BTW)

They have been using the prototype excuse for too long. It just cannot fly much over the height you have seen already. Not enough power. It's just a glorified hovercraft. That's all it will ever be. They will keep "development" going as long as the money is there. Who wouldn't?

your closing statement just answered your own question... They don't go higher because of safety issues, this is only a PROTOTYPE. You would be a complete fool to take this thing off the ground any higher at the stage it is in

OK look. You guys need to fess up. It can't fly higher without a massive increase in thrust also known as horsepower at the same weight . Whenever someone builds an intriguing device like that, puts a price on it, announces an approximate sale date, it's for one thing only...to attract more money from investors. If it would fly higher you would have flown higher already. Jeeze do it over a swimming pool for safety or just fly it to the top of a two story building and land on top....can't do it.

i just finished watching a vid where the guy went at least 25 feet n the air, just look up ''jetpack man''

...except that ducted fans don't interact with the wing-in-gound effect in the same way as helicopter blades. There is no 'ground-effect' for jet/thrust based A/C.
They are staying low because, a) they're indoors, and b) it's a prototype.
