Factual error: The caps worn by sailors on ships, always have the name of the ship, along with the hull number. However, the caps worn by the crew of the USS Reprisal was "CVN-35", where the hull number of the ship they used "69"
Factual error: At the beginning of the episode Rabb evades two heat seeking missiles while flying a Mig-29. When Sarah asks him how he did it, he explains that he got them between the missiles and the sun which made the missiles target the sun instead since "it is a bigger target." While the sun is indeed a far larger source of infrared radiation than a fighter jet, all anti air missiles since the 1950s come equipped with navigation systems in their nose that contain an optical filter. This filters out unwanted data, including the specific infrared radiation coming from the sun. Hence it is impossible for modern anti-air heat seeking missiles to target the sun.
Chosen answer: When landing on an aircraft carrier, a pilot "calls the ball" by confirming to the landing signal officer (LSO) that they have the carrier, and more specifically its landing guidance systems in sight. Carriers use a Fresnel lens system which is a light only visible at a certain angle, so if a pilot sees the "ball" they are at the correct altitude and glide slope for landing.
