There is so much engineering that goes into airports in general as well. To add to the video's material:
All the navigation aid antennas and lighting poles near runways have to be frangible; i.e. fail in a controlled manner when crashed into to minimize damage to aircraft.
A flat apron (the parking space for aircraft and where cargo and passengers are loaded and unloaded) is great for easy maneuvering and towing. However, it will flood easily in rain, so a graded apron is better. But the grading must be carefully designed, else under icing conditions planes, tow trucks, and even people may slide downhill or be hard to control. There are specs for grading airport aprons.
To minimize the traffic of fuel trucks, many airports have a system akin to fire hydrants to deliver fuel under pressure directly to parking spots. One end of a hose to the airplane, the other end to the "fuel hydrant". To further take advantage of this system, many modern aircraft are designed with a single refueling point and a selector panel that ground crews can operate to fill separate tanks as needed instead of filling individual tanks on each aircraft, which requires hose repositioning.
Airports can be surprisingly complicated to navigate on the ground, as there are many taxiways. Especially during the night or in bad weather, people have gotten themselves lost (or even used the wrong runway, which tragically resulted in fatalities). On many airports, you can request a "follow me" car, which does exactly that. A person familiar with the airport will drive to you, and guide you to a parking spot or runway.
The iconic control tower look is there for a reason; the glass angle minimizes blinding sun reflections to aircraft approaching runways, and minimizes internal reflections for controllers.
All airports will have a light gun to issue signals to non-radio equipped aircraft. Yes, flying without a radio is still legal in 2026. No, it is not a good idea to use busy airspace in a non-radio-equipped aircraft.
Runway numbers and letters are not random; they are based on the runway's orientation. Instead of typing another paragraph, here is a video on the topic: https://www.youtube.com/watch?v=HSRmfNDk87s
