Inside the castle there is a huge room with huge internet access terminals connected to Vatsim and Employees manning them for Vatsim 12 hours a day lol. (see this for the idea, or in a larger version of same. Also my own 757 Full Cat D simulator for my own flight training (you don't think I'm not going to fly those aircraft I own myself do you? lol)
I also set up a server for Vatsim myself, and have IT specialists to maintain it, and write new programs for it, such as an automated ATIS/Voice ATIS system, and area CTAF/MBZ frequency areas.
Any left over money goes into making more money

We also make an Operation Get Elli... whatever may occur from that, though I'd like to keep it all legal.
