A shuttlepod of the Enterprise-D that exploded in 2366 while Data was ferrying volatile hytritium, an accident staged by the collector Kivas Fajo to cover Data's abduction.
The Pike was a shuttlepod of the Enterprise-D, named after Captain Christopher Pike.
In The Most Toys, the Enterprise needs hytritium to neutralise poison in the water supply of Beta Agni II. The substance is too unstable to beam, so Data carries it across from the trader Kivas Fajo's ship Jovis in the Pike, one load at a time. On the last trip the pod blows up.
The crew finds traces of the materials Data is made of in the wreckage and mourns him. In fact Fajo had seized Data for his collection of unique objects and planted the right elements in the pod. Suspicion grows when the poisoning proves to have been deliberate, done by someone who knew that only Fajo could supply the cure.
