SmartFlying an extension to make formation flight using SmartCopilot. SmartFlying is a Lua script for FlyWithLua that allows formation flight on X-Plane over the internet, without the need of a dedicated server (like IVAO, VATSIM, ect.). It uses SmartCopilot to establish a connection between two remote users and share the data while it handles X-Plane's AI-Aircraft to show the position of the remotely connected aircraft. Currenty it has been tested on Linux (primary development platform)
