One such drone was launched by the UNSC Walk of Shame and recovered by the CMA Heracles when the former left Harvest and the latter arrived. It picked up the transmissions from the AI Mack to Sif while they were hiding in Jotun Heavy Industries' machines during the glassing of Harvest. This information was later accessed by Dr. Catherine Halsey.
