correct me if I’m wrong but I don’t think the second stage is meant to be caught. It will have legs to land on Earth/Mars without any landing infrastructure.
Pretty sure the Artemis lunar missions are going to use a different vehicle for Earth to LEO and LEO to Earth, so I don’t think anyone will be inside a Starship belly flop for quite some time
Plus, their 'evidence' is a leading conversation with an LLM. It's the AI equivalent of a conspiracy nut taking 50 tangentially related articles about Apollo and stitching together a narrative about how the landings were faked.
