coondoggie writes "Communications and effective system control are still big challenges unmanned aircraft developers are facing if they want unfettered access to US airspace. Those were just a couple of the conclusions described in a recent Government Accountability Office report on the status of unmanned aircraft and the national airspace. The bottom line for now seems to be that while research and development efforts are under way to mitigate obstacles to safe and routine integration of unmanned aircraft into the national airspace, these efforts cannot be completed and validated without safety, reliability, and performance standards, which have not yet been developed because of data limitations" Link to Original Source

and end up with the atomic bomb.
