I love flying in helicopters (in real life and in the sim) but even I would be a little anxious on an open-air, peroxide powered...thing.

Reminds me of the Fairey Ultra-Light that first flew in 1955. http://www.aviastar.org/helicopters_eng/fairey_ultralight.php

Although it used a conventional gas turbine it worked on exactly the same principle. The main problem was that it was very noisy. I see from the video that they still haven't overcome that. The article on this new Dragonfly mentions no tail rotor but I see the prototype still has one while the Ultra-Light didn't.

There's a video of the Fairey Ultra-Light at the 1958 Farnborough Air Show here (about 3 minutes in) --> http://www.youtube.com/watch?v=RktYJnO-3yM
The whole video is worth watching.

Very impressive technically, but it looks like Santa's sleigh and it makes a terrible racket. Grin

The issue is not the lack of wings, the issue is that the wings are moving faster than the fuselage (hopefully) Grin

I flat out just don't think it looks safe, and while I was dispatching a couple of days ago, I showed this to some of my classmates that were waiting around for flights and such, and they all agreed too. One person even thought it was a video that would eventually lead to the pilot crashing.
