Witnessing is crucial to public engagement with war, but the remote violence of drones presents distinct challenges: its victims are largely invisible to Western publics; operations are cloaked in secrecy; and promises of precision targeting, accurate surveillance, and legal monitoring obscure the brutalities of the system. With so many barriers to witnessing, remote warfare tends to remain on the periphery of political debate and has not occasioned widespread resistance. Yet the means for witnessing drone warfare exist; the question is how they might be leveraged to make remote war more accessible and contestable. This article analyses the high-profile drone strike that killed 10 civilians in Kabul on 29 August 2021 to consider the limits and possibilities of witnessing drone strikes, alongside the database of conflict monitor Airwars and the aesthetic practice of the research agency Forensic Architecture. It argues that witnessing drone strikes requires assembling new conceptual techniques with long-standing practices of media witnessing and human rights testimony. It is not a manual or primer but rather maps four critical, analytical, and ethico-political trajectories demanded by the problem of how to witness a drone strike: lived experiences, violent mediations, infrastructural scales, and aesthetics.
