The siting may list only a minute or two. The data from two sites is quickly reduce on a personal computer producing a three dimensional track of the target. The result is displayed graphically against the local train along with velocity, turning radius, and other precise parameters. This information will be on the Web within a few tens of minutes of the siting. Various objects seen in the sky will have very distinctive tracks.
Airplanes can only fly so fast and turn only so sharply.
As can weather balloons. Venus seen through a tricky atmosphere will be obvious when simultaneous observations from two sites are available. Known phenomena can be eliminated with confidence. Unknown phenomena can be openly studied and the data subjected to review. The missing key is the recording Alt-Az mount.
