The following is a list of unnamed Class 1 shuttles.
Paris' family shuttle
Owen Paris used to take his son, Tom, up in this "old Class 1" during his son's youth. Tom later suggested using a Class 1 on the holodeck after Kes asked him to teach her how to pilot. (VOY: "Fury")
This shuttle was only mentioned in dialogue.
This may be an alternate name for the S class shuttle, which Tom stated that he first learned to fly in at the age of eight, or likewise the class of the family shuttle Paris sank in Lake Tahoe at sixteen.
