The TV series and the animated series of Planet of the Apes both ended in a similar fashion. In the TV series, human inventor Leuric and chimpanzee Galen piloted a primitive hang-glider along the coast, escaping from apes who gave them up for dead. In the last episode of the animated series, astronaut Bill Hudson and chimpanzee scientist Dr. Cornelius fly a primitive hot-air balloon back to New Valley with a book which Cornelius will use to prove that intelligent man existed before intelligent ape.
