In 1806, Isambard Kingdom Brunel was born in Portsmouth, England. The Doctor met Brunel at some point prior to his sixth incarnation. (TV: The Two Doctors)

In an alternate timeline, the Eighth Doctor and Charley Pollard foiled a Nimon invasion of Earth. They chased Sebastian Grayle into Wycombe Caves and then pursued him to the Hellfire Club, hoping to interfere with his attempts to psychically summon the Nimon invasion force. They failed to stop Grayle's signal, but repelled the Nimon invasion with only limited loss of life at the Hellfire Club itself. (AUDIO: Seasons of Fear)
