BBC News posted a small article today on several tiny UAVs that were revealed recently by Israeli Military. There are two "mini-drones", called Birdy and the Spy as well as two "micro-drones", the Mosquito and the Mosquito 1.5. The Mosquito UAV, the smallest of the group, has a wingspan of 33 cm and weighs just 250 grams. The UAVs are already being used by ground units to gather aerial intelligence on terrorist activities in the Palestinian territories. A Haaretz News article mentions these UAVs and there's also a Slashdot article on this one with the usual well-informed user comments. And, last, a mention of a planned, 100 gram UAV the size of a credit card can be found in an AFP press release from earlier this year.
