This is wonderful television. Sometimes Serling got a little maudlin. In this, he cooks up a situation, puts his characters into play, and treats them with respect. We have the RAF with its codes of honor, its fighting spirit, suddenly thrust into the future. One can't help but say, "This is the way a British officer would act under these circumstances." Once he comes to realize that there is little hope for him in this world, he fights to return. There are elements of time travel that are tricky, but this episode deals with the real humanity of the characters. The modern brain trust is pretty much as we would imagine. They don't know what to do with this guy and they feel for him. It's a really good story.
