A Space Shuttle or Shuttle? Or Something Like That?

He saw it on more than one mission. He's and have any other astronauts reported this? Not specifically just story. And he's seen this multiple times. But we also don't know if he's the only one that was like peering out that long. Now I wonder if it's, he needs to get his eyes checked, parasites in his eyes or something. That is definitely something rather grotesque to consider but I'd rather think that he just had the misfortune of being on similar orbits more than once with the same thing. Seeing space is big and seeing the same thing multiple times.
