The UFO Mystery of Hessdalen, Norway - Researcher Dr. Erling Strand speaks with Richard Dolan about what he knows

The remote village of Hessdalen, Norway may well be the scene of the longest continuously recorded UFO activity in the world. For more than forty years, people have observed -- and scientists have recorded -- highly unusual and so far inexplicable phenomena there. 

Especially high activity of Hessdalen lights took place from December 1981 until the summer of 1984 when lights were observed 15–20 times per week. Since then, the activity has decreased and now the lights are observed some 10–20 times per year. 

Some researchers believe that that bubbles of ionized gas are created when sulphurous fumes from the River Hesja react with the humid air of the valley. The geology also forms electromagnetic field lines in the valley, which could explain why for example orbs of light move around, but that has not been proven and it doesn't explain all the other unknown objects appearing over Hessdalen from which some of these objects appear to have involved craft under intelligent control, others have not. 

Now, Dr. Erling Strand has studied the Hessdalen mystery since the beginning and speaks with Richard Dolan about what he knows.
