The author chides the military's recent fascination with UAVs, noting that remotely-piloted vehicles are nothing new. This is, of course, true; target drones have been in existence since the 1920s. In fact, the US Army Air Corps' Radioplane OQ-2 drone, constructed during the Second World War, was produced in factories manned mainly by women, including a young lady by the name of Norma Jeane Baker (who would later change her name to none other than "Marilyn Monroe").
In essence, unmanned aerial vehicles are simple devices. In fact, the US Army's portable RQ-11B Raven system is little different than the model aircraft that have been used by hobbyists for decades.
The article notes that interest in unmanned systems seems to wax and wane over the years; after all, most nations are wary of unmanned aerial vehicles buzzing through through congested airspece. Nevertheless, with recent improvements in communications technology, it's a safe bet that all sorts of organizations will be employing these systems in the future. And I doubt pesky airspace regulations will matter much to them.
