Felix,
...make the aircraft disappear from the listing in FS
My interpretation of Locke's ?? was how to remove AI aircraft from the 'Select Aircraft' list in FS.
I dont know that 'Aired' presents a list (except for the 'recent' list under the 'file' menu). You 'browse' from an Explorer window to open an .air file.
Microsoft FSEdit displays a listing of all aircraft in the 'aircraft' folder, taken from the 'Title=' entry, including ai.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
