The following is a list of unnamed S class shuttles.
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 Alice 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." (VOY: "Alice")
This shuttle was only mentioned in dialogue.
In the unrevised final draft of the script for "Alice", instead of a "S class shuttle", Tom said that he learned to fly with "a vintage Piper Cherokee" adding that his father kept shouting "Stick and rudder!" "Stick and rudder!"
This may be an alternate name for the Class 1 shuttle, mentioned in "Fury", which Paris stated his father took him flying on in his youth. Likewise, it may have also been the family shuttle Paris spoke of in "Vis à Vis" that he sank in Lake Tahoe at the age of sixteen.
