Krypton Radio has reported that two previously lost episodes from Doctor Who's early years have been recovered from a private collection! According to the article, "Episode 3 of the William Hartnell adventure “Galaxy 4″ and Episode 2 of Patrick Troughton’s “The Underwater Menace” have been returned to the BBC archive. The episodes were thought lost forever, but had been purchased by film collector Terry Burnett in the early 80s – Burnett hadn’t been aware that the canisters contained the lost footage."
If you're a fan of Classic Doctor Who, this should be a real treat. With a tip of the proverbial hat to K.R., here's a YouTube clip from "The Underwater Menace".
