Roland Piquepaille writes, "the Bats from the MLB Company are man-portable unmanned aerial vehicles (UAV) systems which can deliver high quality video imagery for a reasonable price of about $42K. They've been on the market for a while, but now, NASA and Air Force teams are testing them as flocks of robot aircraft for monitoring wildfires, according to a San Diego Union-Tribune story. These planes have a wingspan of 5 feet, weigh only 15 pounds, and can fly for up to six hours. The best thing is that they can fly during the night, thus avoiding any potential conflicts with other aircraft such as air tankers dropping fire retardant. Still, they are awaiting FAA approval before being allowed to fly around passenger-carrying aircraft."
