A firsthand debrief transcript captures Thomas Stafford and Eugene Cernan describing unexplained "flashing lights" and "sparkles" observed during their three-day orbital mission — in their own words, ten days after splashdown. What makes this record stand out is its source: two experienced military pilots in a structured NASA debrief, not a UFO report, matter-of-factly accounting for something they couldn't identify while circling Earth at 17,000 mph.
