NASA-UAP-D025, “Apollo 16 Scientific Debriefing”
An audio recording of the Apollo 16 scientific debriefing captures a moment that's easy to dismiss and hard to forget: a speaker, mid-analysis of experimental data correlations, casually floats "could be an alien starbase or something, I don't know" before apparently moving on. Whether throwaway humor or something that slipped out in a room full of people who'd just been to the Moon, the context surrounding that remark is what makes this record worth a careful listen.
At 32:41, the speaker makes an off-handed comment, “Could be an alien starbase or something, I don’t know” when discussing correlations between experimental data sets.
