Willease's Space Anomalies: Gemini XI
This is a well documented sighting by an astronaut on the Gemini 11 mission, has yet to be explained. Plus it made a good video. After yesterday's live stream incident, it may pale in comparison. But considering this happened back in the late sixties, I'm stunned such high definition images are publicly available...if you know where to look. (hint, the video description) Enjoy!
