cnet-declan writes "Unmanned aerial vehicles (UAVs) have been flying over Iraq and Afghanistan, but now the Bush administration wants to use them for domestic surveillance. A top Homeland Security official told Congress today, according to this CNET News.com article, that: "We need additional technology to supplement manned aircraft surveillance and current ground assets to ensure more effective monitoring of United States territory." One county in North Carolina is already using UAVs to monitor public gatherings. But what happens when lots of relatively dumb drones have to share airspace with aircraft carrying passengers? A pilot's association is worried."

UAVs are something we're going to have to get used to. Up next: pilotless passenger planes. Most modern aircraft are already equipped with auto-takeoff, auto-pilot (cruise), and auto-land. What more do you need? The ability to control them from the ground? That's being worked on for security reasons.

Personally I am mixed on this program, I believe that border security needs to be strengthened but at a pilot I am kind of scared of being forced to share airspace with UAVs, and the pop-up TFRs that go with them.
TFRs are the bane of private pilots because they are often short notice, large enough to be an inconvenience, but small enough that you can transit most of the center of what they are trying to protect in under a minute, and Part 121 and often part 135 traffic is most often exempted (the aircraft that can do the most damage). Here in Florida for the shuttle launches we have 24 hour TFRs (the TFR is post 9/11 NASA had used a set of restricted airspace that was much smaller or oriented downrange), that are so large that it cuts off East coast VFR corridor between Orlando's Class B airspace and the ADIZ. Forcing pilots to fly an obstacle course of TFR, restricted, and controlled airspace to get to their destination.

Endurance is a concern. Collision avoidance is a concern. But UAVs offer incredible surveillance opportunities that stationary sensors just can't match.

Who is flying them? (Score:5, Interesting)
It's a clear violation of airspace safety in which the pilot is ALWAYS reponsible for avoiding other aircraft. It's the most basic rule you learn when you become a pilot, and it's what every examiner checks for before each maneuver during the practical exam. Unfortunately, the engineers designing these things aren't pilots or air traffic controllers and have no idea how our airspace works. (They work fine in Iraq, but that's a war zone with no civilian aviation.) Apparently engineers do know how to weasel our tax dollars to fund their overpriced remote control toys.
If AI was smart enough to fly an airplane, why aren't they flying airliners? They'd be way cheaper than pilots. If there's no pilot, there's no see-and-avoid. When a camera can see and process as quickly as a human, then it might work, but before then, the only way to do this is to not allow them to fly anywhere near humans fly.
There's currently no FAA-approved technology to relieve a pilot of her duty to see and avoid other aircraft whether or not the AC is on an IFR flight plan. Next time you're on an airliner, listen to the channel with the pilots talking to TRACON or CENTER. There's a lot of human interaction.
In the late seventies, CIA funding changed from human intelligence gathering to satellite intelligence gathering. We can see every place in the world and pick up all their signals, but we still couldn't tell India was testing an Atomic bomb. With all the billions of dollars spent on overhead technology, we still haven't found Osama. Now the people selling the things tell us how similar technology will solve our crime problem...

John Taylor Gatto [johntaylorgatto.com] tells us in his books & presentations that the government's schools were set up to provide workers for industry. Before government schools, the American dream was an independant livelihood. After government schools, the expectation shifted to finding employment with a good company with good benefits.
The problem is that the same group of people are behind both efforts. Is it really so odd to propose that a small, dedicated group of families has been steadily concentrating wealth in their own pockets for centuries?
Furthermore, why is it that the same group of rotten scoundrels install themselves in government? George H. W. Bush was in the CIA at least as far back as the 60's. Head of the CIA, Vice President for 8 years, president for another 4.
Donald Rumsfeld [wikipedia.org] was in the Nixon, Ford & Reagan administrations, according to Wikipedia. He even got his picture taken [gwu.edu] with Saddam Hussein back in 1983. Now he's secretary of defense. Dick Cheney was Secretary of Defense under Papa Bush, and before that he got himself elected as representative from Wyoming.
I'm sure there are more examples. The problem, as I see it, is that the same rotten bastards keep getting recycled through the political system. Watch for the keywords: Project for the New American Century, Bilderburg Group, Trilateral Commission, Council on Foreign Relations, etc... And that's not even mentioning the more secretive enclaves. See The Controllers: Secret Rulers of the World [amazon.com] for a timeline of the consolidation of power over the last 100+ years.
What's more, anytime this sort of observation comes up, the masses have been conditioned to just snicker and dismiss the messenger as a "conspiracy theorist". But how do said masses know that there is no conspiracy? They don't "know", but social conditioning has implanted a nearly impervious belief.

We also have to go through an extensive (by some measures too extensive, by others not extensive enough) system of registration and permit application, depending on the class of weapon. We ban the mentally ill, criminals, and many other people from owning firearms.
2.) Depending on the numbers you use, the United States has fewer violent crimes than many other nations (I don't remember the exact details, however. I am sorry), and that crimes such as muggings and home invasions are down due to the fact that many criminals are afraid of being shot. Of course, like many numbers, these are subject to debate, so we can practically ignore them. But still, it is a compelling possibility. However, it is a documented fact that in many countries where gun possession is illegal, knife and other weapon crimes increase substantially.
3.) So most of the rest of the civilized world thinks our gun policies are "ludicrous"? Switzerland [wikipedia.org] actually has a required period of military service for all able males, and many afterwards serve in a militia capacity, and are therefore ISSUED an assault rifle by the government. Also, it is the "only country in which it is lawful to make your own black powder". From what I gather they have quite a low crime rate. Australia [wikipedia.org] also has historically lax laws on guns due to high need for guns as pest control and a low crime rate, which is kinda funny for a nation decended from a penal colony. That is changing due to increased crime rates in some areas, but still, they're relatively hands-off on guns. Finland [wikipedia.org] also has similar gun laws, as they have alot of huntil in their nation. They are also one of the few countries where silencers are completely unregulated (here in the US I believe you can apply for a permit, but not always, and it's very difficult to get). Many of these countries also have a high emphasis on gun safety, which many of the true hardcore gun people in the US would also say is very important.
In conclusion, our gun laws may be among the more "loose" or "unrestrictive", and there are many unfortunate things that happen due to this. Personally, I think we could due to have slightly better control of the situation and tighten certain parts of our gun laws up. But we're not the only ones who like our guns. There are a number of other, well respected nations, that have fairly loose gun laws, much like our own. We're only a target on this matter because we're the biggest nation of the bunch, and we have a large imprint on the world scene in other matter.
drugs (the war on drugs can be won, all pot smokers are criminals, drug abuse is a disease (for crying out loud))
It could be won, but even if it can't we should still fight it to at least reduce the damage done. Drug abuse is a disease, much like manic depression and other mental disorders are diseases (for example, cocaine abuse renders the brain incapable of gaining any joy from anything but cocaine. That's why it's called abuse, boys and girls. As for the pot-heads, perhaps our laws are a bit too heavy on them, and that maybe it should be legalized along the same lines as alcohol and tobacco, but frankly I don't know enough about the situation to make a judgement.

Presumably they could become so numerous as to make private flight planning a bit difficult. Before then, however, there will probably be enough crashes with drones to result in them be forced into small saftey zones.
