In some ways this has similarities to Star Trek IV, the Voyage Home as we see an interaction between some of the USS Enterprise crew and the then contemporary (late 1960's) America. Watching this in 2020 is an incredible experience as we see footage of US fighter jets that at the time were at the forefront of technology but now hail from a lifetime ago. It's a real tribute to the show that you forget that this was made 50 years ago and believe that Kirk too is looking back in time. The scene where the fighter pilot spots the Enterprise is an iconic one and there are plenty of clever touches in this episode that make it one of the best in Season 1
