We've just posted a short excerpt from our footage with the pilots who fly unmanned Predator and Reaper planes over Iraq and Afghanistan. The planes are in the war zones; the pilots are at an Air Force base in the desert north of Las Vegas. A colonel tells us how his unit struggles against the possibility of detachment as they experience combat remotely. Some pilots, however, are able to so completely immerse themselves in conducting battle via video screen that their nightly return to suburban life in Las Vegas becomes all the more jarring and challenging. Watch our rough cut here, and let us know what you think -- there's a space for comments directly below the video. As the national debate over strategy in Afghanistan rages (see FRONTLINE's season-premiere report, "Obama's War"), we would love to hear your thoughts.
