"The Air Force says no such experiment took place.
In his talk, he had described a simulation in which an AI-enabled drone was repeatedly stopped from completing its task of destroying Surface-to-Air Missile sites by its human operator.
He said that in the end, despite having been trained not to kill the operator, the drone destroyed the communication tower so that the operator could no longer communicate with it.
"We've never run that experiment, nor would we need to in order to realise that this is a plausible outcome," Col Hamilton later clarified in a statement to the Royal Aeronautical Society.
He added that it was a "thought experiment" rather than anything which had actually taken place."
