I hope everybody who views this thread understands that yes, the thingy's up there are useful. But until the rush to integrate is tempered by a stringent design/build/test requirement equal to, but preferably more stringent than that for manned aircraft, I fear we will see headlines that will for a long, long time, possibly forever ban the use of unmanned air vehicles except in restricted airspace/combat zones.
Many issues will remain even if this one is solved. If the thingy does get away and hits/destroy's, god forbid kills folks, who is responsable, the builder, software designer/intergrator, operator?
In the ground side (and the air if the sense and avoid goes forward)the big problem with unmanned/manned interface is that you can program unmanned to work together, sort of. But what is extremely difficult is that you cannot program responses to us humans. Why because we react unpredictably. Again who is going to pay if something happens?
Long roads to travel methinks.
