Lieutenant Thomas Dodge (1942-3978), Science Officer, and Lieutenant John Landon (1940-3978), navigator, portrayed respectively by Jeff Burton and Robert Gunner in Planet Of The Apes (1968), were the two surviving crew of Liberty 1 who accompanied Taylor across the Forbidden Zone.
Their fate is well documented: Dodge was killed in the hunt in which Taylor was shot and captured, and ended up a stuffed exhibit in the Museum Of Natural Science (a.k.a.the "Zaius Museum"). It's been stated (in the Escape From The Planet Of The Apes novelisation) that Dodge was considered a "unique specimen" as the apes had never encountered a black human before. Landon was captured alive, but subjected to brain surgery during which the ape scientists lobotomised him and turned him into a vegetable. In Beneath The Planet Of The Apes Cornelius hints that Landon was also displayed in the Zaius Museum.
