"Unmanned aircraft pose myriad problems to US airspace, GAO reports"

this is an interesting article (for those of us in the lower altitude range, and high altitudes for some aircraft):
"Unmanned aircraft pose myriad problems to US airspace, GAO reports"

an interesting point is that the global hawk is actually autonomous (rather than remotely piloted).

i'm assuming that, with flight following, ATC would be able to see most/all unmanned aircraft and advise of potential conflict. i do wonder though, in a conflict situation, what action the other aircraft would take assuming it detects you.
