This is incredible:
Lockheed Martin is looking to supply the Pentagon with flying cameras …. A miniature payload module about the size of an Altoid can be carried by this single-wing Nano Air Vehicle (NAV), sized and shaped like a maple tree seed. The minuscule vehicle is packed with navigation and communications equipment, imaging devices, and sensors that sniff the air for chemicals or detect signs of life such as body heat and breathing.
