According to http://pointa.autodesk.com/local/eng/portal/resou
a tonne of TNT has 4.2 * 10**9, so about 2 * 10**5 tonnes TNT, or in human speak, about 200 kilotonnes.

It's probably not the best example, but the Avrocar [autobahn.mb.ca] comes to mind. It's tantalizing, because it was an actual flying saucer that was being developed just when the flying saucer stories started to become commonplace. The funny thing is that, although the project was secret, it wasn't to hide it from the Soviets. Avro was more concerned about other aircraft companies with deeper pockets, that could have leapfrogged their development effort if they'd gotten wind of it.

While this is a very cool technology, and quite the advancement, I wonder how practical it is. Like large aircraft, it has many limitations on movement: forward or... forward.

Micro Airplanes Laboratory - Demo (Score:5, Interesting)
They've developed an algorithm that can scan the horizon and auto-determine the horizon. In a side-by-side comparison between a human pilot and computer, the human could make you very sick. The vidoe jumps as the plan flys very erratically. With the computer algorithm, the plane flies smooth.
Another note, they use a PC to do the processing. The demo guy actually has an Apple laptop and runs all the video in quicktime. The PC processes the avi quicktime video, and returns the flight control info to the micro-flight airplane.
Another not, they are funded heavily by the DOD.
Another problem is fuel. The micro-planes only have enough fuel for a few times around a football field, and their range is similarly limited.
Finally, the coolest video they have is where the plane tracks a moving vehicle, and follows behind it.

Discovery Channel covered MAVs (Score:5, Interesting)
As someone who's also done this I can tell you that it's still important to have the vehicle in direct visual line of site if you want to be sure and get it back.
When looking at the world through a remote video camera without the benefit of an artificial horizon and other instrumentation, it's very easy to get a small model into a spin or spiral from which it is difficult to recover. Being able to directly see the model from the ground is the only safe way to ensure you can regain control in such situations.
The problem is one of orientation -- once you lose view of the horizon through the camera it becomes very difficult to tell what your plane is doing -- thus very difficult to feed in the proper control corrections.
If it weren't a breach of copyright I'd post the DivX video I made of that Discovery broadcast -- it was really quite interesting.
"Simple" solution... (Score:3, Informative)
What about automatic pilots, though? For example, the AeroVironment Black Widow [aerovironment.com], which is a six-inch aircraft, has "altitude hold, airspeed hold, heading hold, and yaw damping" (from the PDF available on their site).
With bigger r/c vehicles, total autonomous flight was achieved a long time ago, even for helicopters, which are much more difficult to stabilize than planes. This can allow an operator to simply guide rather than actually pilot a vehicle, with greatly reduced chance of error.
This already exists in commercial technology: there's an r/c helicopter, made by Honda iirc, used for applications like cropspraying and aerial photography. An operator can fly these with minimal training, because stabilization is automatic.
Re:Discovery Channel covered MAVs (Score:2)
Then the solution is auto stabilization, like the previous poster mentioned.
Another solution (for human pilots) is to immerse the virtual pilot better by using two cameras instead of one -- for stereo separation -- and gimble it to match head movement.
Human pilots shouldn't be flying these things anyway; they should be guiding them, just like how the rest of non-recreational aviation is going to end up in the next few decades.

Solution to low battery and hover problems (Score:5, Funny)
Humming-birds have wings and can hover. They also have the ability to fly for extended periods, and when they get tired they can perch on the nearest ledge. Obvously, technology is not at the stage where this could be easily implemented into a Humming-bird sized package, and cheaply. However, Humming-birds themselves are relatively plentiful. What if, you attached a minature camera and transmitter to.. a Humming-bird? "But you cant control it!!" i hear you say. What if, you attached electrodes in such away that you could control, or atleast influence the flight. The bird would still keep priority control for dodging obsticles and landing when tired, but you would be able to control the basic directional element, and the direction of the camera. If you employed a flock of Humming-birds you could maintain a good deal of coverage for any event. Also, Humming-birds come with AI and basic flight control systems built in reducing the need for on-board electronics witch in turn reduces weight. For example, the bird has a built in gyroscope and can automatically 'right itself and maintain level flight.
The battery life of the camera could also be extended by attaching the power and/or data cables to the bird and having them trail behind, this would also prevent the bird from going out-of-range.
The millitary applications for this are also good - since no-one would look twice at a Humming-bird on a battle feild, they could be fitted with explosive devices to create humming-suicide-bombers (although the payload would be small).
