Skygate is a big corporation that first invented an upper atmosphere flights in 2083 and after that they are still maintain a monopoly in that field. These kind of flights are really fast and economically reasonable (you can get from London to New York just in 30 minutes) First time they had a lot of problems with landings and take offs due to sophisticated construction of the shuttles. Also it was expensive because shuttles consumed a lot of fuel taking off as well as more dangerous. After 10 years of service they finally invented another feature - a space elevator. They managed to build special hubs in the upper atmosphere and get people there by elevators. Shuttles now need to fly just between these hubs without landing on Earth, flights became safety and more affordable.
So here is one of those hubs.
