A new startup company thinks using hand-rolled UAVs can solve previously unsolvable problems of international aid. Primarily the "guys with guns take aid packages before they get near the intended recipients" problem. Right now even their "heavy" quad-copter is only scheduled to carry about four pounds, so I don't think they'll be replacing trucks any time soon. It also removes the potential for graft from a whole host of middle-men, both at home and abroad. But as far as pipe dreams go, hey, at least this one has radio-controlled helicopters in it!
