Original air dates in October of 1966. Internet tells me this is the last episode for Mr. Hartnell. Sadly, the final episode appears to be missing.

Original air dates September and October of 1966. Start of season 4, and more lost episodes. According to Wikipedia, not a single serial is intact. Lots of slide shows to watch.

Original air dates were June and July 1966. The TARDIS arrives on a modern-day street, cheerfully letting it’s police box disguise work. The Doctor has a cunning sign, “Out of order” for it.

Original air dates May and June of 1966. Another sequence of lost eposides, reconstructed with stills and subtitles. Off to a dubious start with Steven and Dodo looking for the Doctor as he wanders around.

Original air dates April and May of 1966. Oh boy, a Western, with music and everything. And the TARDIS, how unexpected.

Original air dates April 1966. Three of four episodes are missing and I get to watch reconstructions.

Original air dates from March of 1966. Off to a solid start with an alien with an eye where their mouth should be, the TARDIS arrives in a jungle. Dodo bursts out, and sneezes. Steven’s a terrible nag.

Original air dates February 1966. France, vaguely mideval times, the Doctor and Steven arrive in the middle of the 16th century.

Original air dates November 1965 – January 1966, a long run with many parts, most of which are missing today. Eleven parts of which we have only three.

Original air dates October and November of 1965. Interrupted the story of “Mission Unknown” for a month leaving the viewers to remember the lost tape.
