I recently added a number of ground vehicles in FSX. The additions were installed via an auto-installer. Later, when I was changing aircraft via the FSX menu, I noticed a large number of thumbnails associated with these vehicles. I dusted off AirEd and went to work making all these vehicles invisible. Most of them disappeared. However, there are about 20 vehicles that are still present in the FSX menu. I went through all the vehicles in the SimObjects\GroundVehicles folder looking for *.air files that I might have missed. I couldn't find any that didn't have the "Aircraft Type=2" statements. I also tried a search of my disk drives with no joy. So, here is my question - Where could these vehicle files be? Or, is there another way (not air file) that these vehicles can be visible in FSX? Thanks Frank
