Really enjoying GSX, the best FSX product out there by a mile!
In terms of future enhancements my wish list would be:
1. After deboarding, the option to be towed to remote parking, if the next flight is not for some time. Then the option to be towed back to a vacant gate when ready for the next flight for catering, fuel and boarding.
2. Medical emergency option. An ambulance meets the aircraft at that gate prior to normal deboarding commences. Possibly the ambulance then takes the patient to a nearby paramedic helicopter (maybe a bit too ambitious!)
3. Technical fault, emergency landing. On landing, fire and emergency vehicles meet the aircraft when it vacates the runway to check it over and then escorts the aircraft to a gate or remote parking for further checks and deboarding. Option for the aircraft to be towed to a maintenance area or hangar for fault repair before next flight.
Keep up the great work FSDT :-)
