A 21st century airport would probably evoke only a weary smile from a person of the year 374 AJR/2379 A.D., because the scales and ideas of size have changed enormously over the last few centuries and have grown to gigantic proportions. With the help of the most modern means of transportation, from gliders and express trains to faster-than-light spaceships, every traveler, no matter where they come from, has the opportunity to cover large to very large distances, even intergalactic ones, in a reasonable amount of time.
The image of travelers laboriously pushing their way through overcrowded queues is a thing of the past. The needs of almost all galactic peoples are taken into account, as are those of ordinary citizens who want to spend their vacation on some distant colonial planet and are now waiting for their ship.
Of course, there are clear differences between passenger and cargo ports. In a passenger port, you will see even less of the technology, where the focus is on comfort and the rapid handling of passenger flows. In a cargo port, you will look in vain for luxury, as the focus here is inevitably on logistics.
In addition to the actual docking bays for spacecraft, the grounds of a spaceport also include shipyards, maintenance facilities, control facilities, power supply facilities, accommodations, barriers, protective and defensive systems, and all associated logistical facilities. A spaceport is usually surrounded by a wall to protect the surrounding area. For safety and environmental reasons, less than 25 percent of all facilities are located on the surface. Beneath a spaceport, facilities extend up to three hundred levels deep. Depending on the spaceport's equipment and local environmental regulations, spacecraft are either transported into the atmosphere by a gravitational field, the so-called "spacecraft lift", or launched under their own power.
The spaceport shown here is a small part of the “Iari'Mhatep Intergalactic Gateway” spaceport, which is located near Iari'Mhatep, the capital of the Intergalactic Union of Sovereign Planets. With a size of 28.57 km², this part represents only a fraction of the total area of this spaceport, which extends over a total area of about 4400 km².
The rear part of the spaceport area is dominated by the 500 m high and 75 m thick protective wall. This wall divides the entire area of the spaceport into several smaller areas with a size of 15 to 30 km², depending on the terrain and function of the area, and fulfills several functions: It provides visual protection when the spaceship engines are in use, serves as noise protection and also acts as a barrier in the event of possible accidents.
In front of the protective wall on the left of the image is the arrival and departure terminal of this section of the spaceport. All passengers are processed here, and customs is also located here. Departing passengers transfer here to the underground shuttle system, which takes them to the actual underground spaceport and to the spaceships. Arriving passengers leave the spaceport through this terminal.
On the right you can see the entrance to the approach lane for the spaceships to the underground part of the spaceport, especially the docking stations and maintenance docks. The entrance tunnel has a diameter of 1,000 meters and is surrounded by a ring containing shield emitters - to close and secure the approach lane in case of a disaster – tractor beam emitters and guide beam emitters - to assist with approach and departure – as well as the Flight Traffic Control Tower responsible for this approach lane.
The access road and the entrance to one of the parking garages can be seen in the foreground. To the left and right of the entrance are the pedestrian entrances to the underground facilities of the spaceport. Around them are several working drones. The rest of the buildings in the picture are various hotels, department stores – always a part of a spaceport, especially for the sale of some of the most delicate products – administrative offices, and traffic control towers, which generally control land and air traffic in this area.

It took a few months. But now I'm finally finished with the spaceport and the accompanying text. The rest of the world won't get to see it until Christmas. But you can see it today.

I really like this, and the story too, and I'm glad to see it first before Christmas 
duh! 
I can no longer open any ROF in Rayletron. The "Access Violation" message appears at first and second attempt. And the third time I try to open an ROF, no matter if I always try to open the same file or a different ROF each time, Raylectron crashes. It freezes and when I click on something, I get the Windows error message “Program does not succeed. Wait for response or exit?”.
