Unknown dates

 * The Doctor visited Professor Chronotis at St. Cedd's College, Cambridge. Accounts existed for both the Doctor's fourth and eighth incarnations having this encounter. (DW: Shada; WC: Shada) There was also an account suggesting that a botched attempt to abduct the Doctor's fourth incarnation (and possibly also his companion, Romana though there are conflicting reports) was made just prior to the Doctor's visit; as a result, the Doctor and possibly Romana were briefly trapped in a state of limbo before being returned to their proper place in time. (DW: The Five Doctors, both original and Special Edition versions)
 * The BBC television series Nightshade starring Edmund Trevithick as the title character came to an end after five years. It was rebroadcast on BBC2 in 1968 (NA: Nightshade)
 * The Tenth Doctor travelled to Dry Springs, and later to Area 51, where he helped ward off an invasion of Earth by the Viperox, along the way meeting Cassie Rice, and Jimmy Stalkingwolf and arranging freedom for two of the gray aliens connected to the famous Roswell crash. (DW: Dreamland)
