This is coolbert:
By definition, all drones are unmanned.
From Core.com this breaking story. Sounds like a reconnaissance and a testing of defenses to me.
"Device, possibly aerial drone, found on White House grounds"
"WASHINGTON (AP) A device, possibly an unmanned aerial drone, was found on the White House grounds during the middle of the night while President Barack Obama and the first lady were in India, but his spokesman said Monday that it posed no threat."
See my previous blog entry, Rezwan and how the Soviet defector described an attack on the White House and the person of the President himself.
This is a breaking story of some importance? Imagine a swarm attack by drones and not just one! What then?
