The Yelchin's blackbox, engraved with only the registry of NCC-4774-(...), was first seen and described in "People of Earth." The name of the ship to which the black box belonged was mentioned in dialogue in "Unification III." The design of the prop was explained by Mario Moreira in TRR: "There Is A Tide...".
According to the novel Wonderlands, the senior officers of the Yelchin were Captain Namid Hacquin, executive officer Iryi Roala, chief medical officer Reiko Kamada and chief science officer Grace Kavanagh.
