//  SimConnect AI ATC Aircraft sample
//
//    Description:
//                Adds AI aircraft to make the flight from Yakima to Spokane busy.
//                First start the user aircraft at Yakima (or load the Yakima to Spokane
//                flight plan used by the AI aircraft - then drive off the runway to view
//                the goings on).
//                Press the Z key to add six AI aircraft
//                Press the X key to give the parked aircraft the Yakima to Spokane
//                flight plan
//                Both keys can only work once.
//                The creation of the 747 shguld fail - as Yakima airport is not
//                large enough for this aircraft.
