Pilots may be thousands of miles away from the flying weapons system they’re operating. They often head home at the end of the day, as if returning from any other office job, maybe picking up milk on the way. But while at work, their drones’ onboard cameras put them in a unique position to watch people being killed and injured as a direct result of their actions.

As psychologists learn more about the mental scarring warfare leaves on drone pilots — caused by long shift hours, isolation, witnessing casualties and those Jekyll-and-Hyde days split between battlefield and home — experts from within the U.S. Air Force are calling for a review of drone pilot selection…

The trouble is that spotting the known positive attributes in up-and-coming drone pilots is harder than spotting the negative attributes. To begin with, Chappelle drew up a portrait of the ideal drone pilot from the recorded testimony of 82 drone pilots and their supervisors in a 2011 report.

Good drone pilots, according to Chappelle’s findings, have excellent memory for pictures and sounds. They are bombarded with sounds and images from multiple screens through their long shifts, but parse that data quickly, cutting through the noise. They’re multitaskers and collaborators.
