I really enjoyed this thread. My contributions:
1.) I will never love any plane as much as the F-16. I grew up seeing the Thunderbirds every year with my folks, watching Iron Eagle with my dad, playing Falcon 3.1 and 4.0 simulators on PC. It still gives me such a thrill to see a fully kitted out Viper. I have a pair of books that track every evolution of the F-16 from the basic F-16A to the current Block 70 models used by UAE and Egypt. I love the F-16 more than just about any inanimate object.
2.) The original post (F-5E Tiger II) is also one of my favorites. When I watched Top Gun I wanted one of the "Mig-28s" not an F-14. No disrespect to the badass F-14.
3.) It's such a shame Russia sucks so much, because the Mig-29 and the various Sukhoi planes (SU-27, SU-33, SU-35, etc.) are so pretty to look at.
4.) I also have an odd love for civvie airliners. I pay $40 a year for the Flightradar 24 Gold app, and each time I fly I know every bit of information about my plane before we fly. I love noting the little differences - and honestly, the LACK of differences sometimes - between a 6 month old, 5 year old, and 15 year old airframe. Modern commercial air travel is a true mechanical marvel created by thousands of professionals following rules established by thousands of screw-ups and learning experiences. Fantastic to experience in that mindset. My favorites are the 757 and the 777, though I've had some great Airbus flights recently with newer A321s.
