Instead of taking the 'dropping a plane' route, you could use the Persistant Trails plugin. Link here: http://forum.kerbalspaceprogram.com/threads/49216-0-24-2-Persistent-Trails-record-share-and-replay-track-data!-(Aug-1-V1-1) If you do drop a plane, then make sure you do it without FAR/NEAR. I did it with FAR, and the plane crashed. I then did it without, and they flew.
