Invisible Boomerang Reconnaissance Robot

The defense industry is taking a page from the Batman School of War and making products with more of a boomerang shape. In this case, the Phantom Sentinel, an unmanned aerial vehicle that's not only shaped like a boomerang, but "is in constant motion" and "has a uniquely minimal cross section allowing it to 'slice' through even the most adverse weather conditions".

Great for both seeing what the local population is up to without being detected and a relaxing day at the park.
