My second appearance at Sheffield Documentary Film Festival this year was part of a discussion about National Bird, a film dealing with the complexities of drone warfare. It takes the perspective of thee drone operators, who put themselves out on a limb by talking about their experience and concerns about such work. 

It was a complex and far reaching discussion in which I covered the relationship between military and civilian drone applications, the idea that losing the human from the field of combat may diminish some aspect of our capacity to take moral responsibility for destruction brought by drones. Other philosophers have made this case and the views of protagonist Lisa Ling, who was with us, made it all the more apparent.
