yes, and no. people are trying to create ufo's for fsx--still in testing of the .air and .cfg files. when they are done, they will be up.
There is one mission in fsx called "secret shuttle" where you fly from Las Vegas to Groom Lake (Area 51). As you are coming into land at Groom Lake (Area 51) you see a UFO fly pass and nearly hit you! :) - There are some modelers who have created superb UFOs and craft from many of the big name sci fi films. These are available o a range of download sites dedicated to Flight Simulator.
