The annual VATSIM Charity event starts today and runs for 2 weeks.
The virtual skies will be particularly busy with fully manned ATC stations.
SimfestUK has an entertaining and interesting feed. Our fellow Airbus builders Captain Horgan and Christoph from Cockpit Concept will also be participating.
