One of the “advantages” of unmanned aerial vehicles is the removal of the human element from much of the operation.  In theory, its inability to get tired, make mistakes, or act with emotion may make a UAV a “better” system.  In theory.

While the UAV may not be able to get “sick,” it is apparently still vulnerable to computer viruses, as public reports indicate has occurred to both MQ-9s and MQ-1s (which are essentially the same UAV).  To be fair, that was likely a result of the “human element,” but the fact remains that UAVs are not always the panacea some may think they are.
