From Popular Science. There is under development a new generation of pilotless aircraft. These are not mere remotely piloted drones. Rather, they have no human pilot. A prototype robot tactical bomber, the Boeing X-45A, has flown simulated missions. It is envisioned that such craft, traveling in packs, will loiter over the battlefield, spoofing enemy radar and protecting each other with defensive fire. They would not be subject to human limitations such as fatigue. They are potentially capable of carrying out longer missions than a human pilot. The article implies that these devices may completely replace the human pilot on some types of missions.
