First, there was the Gravity Plane, a concept so obvious, I'm surprised it took this long to make it to the almost-practical stage. The video tells the whole story.
Now, we have the Air Trailer, a brilliant application of one of the most straightforward and easy phases of flight, the aerotow. Their website needs work, but the video is just as convincing as the one on the Gravity Plane.
Both projects probably need investors. I hope I'm not too late.

I'd go for it but all my money is in the Moller Sky Car. There will be one in every garage...
I thought all gyrocopters were disposable.
So, we have a perpetual motion (er, flying) machine, and a glider trailer.
Nothing like a rocket-blimp, I say. And, one pitch up of the latter on takeoff will be the end of their liability insurance coverage.
What WILL they think of next?!?!?
A rocket-blimp! Good idea. I bet we could find one of them on the web if we looked.
Sounds like a perpetual motion device to me.
Meanwhile, I vaguely remember reading in recent years about an actually built (or perhaps also only an idea?) "gravity submarine" doing the same thing this aircraft is supposed to do, but underwater.
Could we use a gravity plane to tow an air trailer full of fuel to Post Mills? That would be useful.
If you combine the Fulton Surface-to-Air Recovery system to the Air Trailer.

And put some seats in the trailer. The airlines could provided a door-to-door pickup/drop off service.

Here is a gravity powered submarine:

It has a max glide ratio of about 3:1 at 0.5 kts (going up or down).
It would be interesting to see if it could work as an underwater sailplane by finding upwelling or downwelling currents. Of course if the glide ratio was better than 3:1 (its more of an underwater hang glider) it would work a lot better.

Here's one that any glider pilot can tell works better:

Cool. I wonder why it isn't symmetrical. It seems that upgliding and downgliding should be treated the same.
Maybe it does a roll and flips "upside-down" when upgliding.

sounds like something Brian Borland would build
Just don't tell him about this:

Those seem real.
It's long past time that NASA was disbanded.
The Air Trailer people took down their video. Too bad. It was quite convincing.
