1. Most of the sightings were concentrated in the night. Regardless of where they are coming from, we wonder where did they go in the daytime?. Sometimes we see an activity being done on the first night was repeated on the second night at the same place and time. Sometimes the same activity might stretched for 3 nights or more. If this happen, there is a slight change in time of appearence and location. Why is this so?.

2. Why are most of the UFOs zeroed into a small geographical region and not spread out over the Earth?. If they are coming from outer or inner space, they should have fanned out on every part of the Earth.

3. There is a space and time limitation in all the UFO "operations" during a UFO wave. Their activities it seem must be carried out in the specific area in a certain time frame. Then all of them, comprising of different types of UFOs and its operators, must high-tailed back home - from whatever or where ever origin(s) they were coming from. Who or what regulates or control all these "operations"?.

4. Why is the UFO wave cycle which is about 10 years (plus or minus 1 year) almost imitate the 11 year sunspots cycle and the 11-year earthquake cycle?. Could all 3 separate events be triggered by a common stimulus?.

5. Why is it that on average there is only one major wave each year? (see the global wave listing).
