Paris' family shuttle  
Owen Paris used to take his son, Tom, up in this "old S-class shuttle" during his son's youth. In 2376, Paris recalled to the sentient starship  that he had been scared out of his wits at first, when he couldn't get the shuttle level, but then there was a "moment of clarity, when suddenly everything made sense."
