FS9/FSX. Oliver has just released the next version of AES and he just can't get these versions and airports out quickly enough. If only competing programs could actually move the jetbridges... FlightBeams Denver will not be available with this update but there are some really great airports that are such as Taix2Gate's KMCO, TFFR & LTBA, ImagineSim's Shanghai, JetStream Little Rock, UK2000 Hearhrow and much much more. Get some credits, get the update, and get flying... or get using AES before you fly! or after you land... well you know.
