The original commanding officer of the USS Luna was Captain Fujikawa. (TTN novel: Taking Wing)

Starship designer Xin Ra-Haverii personally blamed himself for a fatal accident in the engine room of the Luna, although those who had been in the engine room (and even some who had not) insisted it was not his fault and that he couldn't have predicted the accident.
