Unmanned cargo aircraft? I don't see it happening...imagine if one of these crash "full of hazardous materials" (as the media will spin it) into a farm field of crops or a water supply lake or a city. I really don't see it in the NEAR future, too many security risks. Risks are too great for what gain? Because we can? Insurance to cover these companies would be too high.
And, ain't no ******** way I'm getting on an unmanned pax plane.
