There are two plot points in this episode that I don't believe are realistic. Ed and Gordo almost losing their jobs because of the dogfight and Tracy Stevens being treated as an inexperienced astronaut when she's on the moon. In episode four, Ed has to bail out of his trainer jet at the end of a simulated dogfight against Gordo. In this episode, we see the reaction of Thomas Payne, Margot, Madison, and Molly Cobb and they don't seem to be based on reality. Fighter pilots have to maintain their skill and dogfighting practice against each other is the best way to maintain those skills A buddy of mine a retired F18 pilot told me that they would frequently dogfight the Air Force pilots from a nearby Air Force Base. Also, Ed is an admiral. He's not a young Navy lieutenant anymore. Nobody would talk to an admiral like that over an airplane. The treatment of Tracy Stevens seems ludicrous. Making her the Linus because she's never been to the moon. She's a pioneer of women in space , who is responsible one of the most heroic acts in the shows universe. The character Nick Corrado, who is the Linus who is in high school when she risks her own life, and saved Molly Cobbs life in space would continue to be the Linus, or they would just stop the Linus nonsense.
