- 2013 June 7, Ed Pilkington, “‘Killer robots’ should be banned in advance, UN told”, in The Guardian Weekly, volume 188, number 26, page 6:
- In his submission to the UN, [Christof] Heyns points to the experience of drones. Unmanned aerial vehicles were intended initially only for surveillance, and their use for offensive purposes was prohibited, yet once strategists realised their perceived advantages as a means of carrying out targeted killings, all objections were swept out of the way.

Usage notes
The sense of man involved is not necessarily the sex-specific sense, but to avoid any interpretation involving sexism, the terms uncrewed and crewed are unambiguous. This distinction is parallel with man/humans (for example, since the dawn of man versus since the dawn of humans).
