Civilian satellites are getting very good. The gap between military and civilian satellites is closing to the point where I know there are discussions about whether or not we're going to need a military satellite system at all, really, eventually, because the technology closes. However, if it's cloudy, it's still cloudy, and satellites can't see through clouds very well. So, again, you get back to some sort of aircraft, be it manned or unmanned, that can fly lower under the clouds and see what the situation is.
Satellites have fundamentally changed the way the world works, as a matter of fact, with Google Earth and all the other things. But they don't replace that closer-in stuff, and they never really will be able to. It's also very, very difficult to task a satellite. Satellites do their thing, and if you need a satellite over an area and the satellite's not doing that right now, then you're out of luck. That's just the way it goes. It's not like in the movies, where you can follow Will Smith around.
