Ultra-Light Micro Air Vehicles
Roland Piquepaille writes "Dutch engineers have built the third generation of the DelFly autonomous air vehicle. The DelFly Micro made its first public flight earlier today in Delft. This micro air vehicle weighs only 3 grams and has a wingspan of 10 centimeters. This very small remote-controlled aircraft carries a 0.4 gram camera. The DelFly Micro, which looks like a dragonfly, can fly for 3 minutes at a maximum speed of 5 meters/second. It could be used for observation flights in difficult-to-reach or dangerous areas."
That's exactly what I was thinking! When I was 12, and I read Raymond Abrashkin's "Danny Dunn: Invisible Boy", I was mesmerized. And this mini UAV is essentially the plot device in the book, right down to the dragonfly appearance. Pretty good prediction for a book from the mid '70s.
