Does anyone know what the story with MIA episodes that aren't on the Lost in Time set is? There's still a few of stories out there that are missing an episode or two:
1.08 "The Reign of Terror" (6-parter, missing parts 4 and 5)
4.02 "The Tenth Planet" (4-parter, missing part 4--the episode with William Hartnell's regeneration)
5.03 "The Ice Warriors" (6-parter, missing parts 2 and 3)
I wonder--is this because they were unavailable at the time of Lost in Time's production, or are they holding out hope that the missing episodes will resurface for these stories?
