These scientists describe their UAV project at the South Pole. Sound familiar?
"Flying a mission is always a little scary. Tom, the project engineer and pilot, stands by with his remote control and flies it a little until a stable flight is acheived, then we engage the autopilot. The plane then turns and heads off into the distance, disappearing from view after about half a mile, and dropping out of radio contact with its computer base station after four miles or so. That part of the mission is the most scary, as we've nothing to do but wait for fifteen minutes biting our nails as the plane follows its plan.
We breath a sigh of relief when we regain the signal and see some coordinates on the screen, but only declare success once we've seen the machine, taken it smoothly back down to the snow, and downloaded the data its recorded."
