Think of it this way: in a glider, most of the stuff that causes
emergencies has been left on the ground.

One could say the same thing of Unmanned Aerial Vehicles. :-)

True, but in the case of UAV, the "stuff" which you'd be referring to is
still "in the loop"...it just has less incentive to avoid causing an
emergency.
