Jenny's bowship

A damaged bowship crashed into Terebek, and dragged the entire moon along with it as it performed time jumps, appearing to its host planet every six months.

When Jenny came to the planet, she travelled to Terebek and discovered the bowship, repairing it and claiming it as her own. Using it, she continued her search for the Doctor. When she discovered the white holes, she used her ship to try and save Jack Harkness and Tara Mishra only for it to be drawn into the singularity's gravitational pull, being saved by the Fifth Doctor.

Knowing that the Twelfth Doctor had remained sedentary for a time at St Luke's University, Jenny set course for the university, crash landing in the Terrance Dicks Library. Her craft was examined by UNIT, infecting its personnel with the white energy of the Void. The Twelfth Doctor, along with his ninth and tenth incarnations, used the bowship to travel into the Void. When the bowship picked up a Type 1 TARDIS in the likeness of the Eleventh Doctor, the Doctor's first nine incarnations, bar the Eighth Doctor, combined the force fields of their TARDISes to reinforce the bowship enough to crash into the Type 1's control room. The crash however left the bowship beyond repair, Jenny instead being returned home by the Ninth Doctor. (COMIC: The Lost Dimension)
