Working Paper No. 10: Ley Lines, Earthlights and UK Earth Fault Lines

This document, titled 'Working Paper No. 10: Ley Lines, Earthlights and UK Earth Fault Lines,' is a technical memorandum produced by the Defence Intelligence Staff (DIS) dated January 26, 2000. The paper serves as an investigation into the hypothesis that UAP sightings are geographically linked to 'ley lines'—straight lines connecting ancient sites—and geological fault lines. The author examines the origins of the term 'ley lines' and the concept of 'orthotenies,' noting that while some investigators have attempted to link these to archaeological and astronomical interests, the statistical alignment of sightings with such lines is considered invalid. The paper further rejects the concept of four-point ley lines based on the grounds of probability. However, it acknowledges a potential, albeit tenuous, connection between sightings and rocky formations that produce tribo- or chemi-luminescence when fractured, suggesting these could create visual effects. A significant portion of the document is dedicated to the 'Hessdalen Phenomenon' in Norway, which was studied by the Norwegian Defence Research Establishment between 1983 and 1984. The research at Hessdalen utilized various instruments, including cameras, IR-viewers, spectrum-analysers, seismographs, magnetographs, and radar. The findings from Hessdalen indicated that while no local seismic activity was detected, there was a correlation between the appearance of lights and magnetic pulsations. Radar data revealed objects moving at speeds ranging from 0 to 30,000 km/hour, sometimes without corresponding visual sightings. The document also mentions an experiment where a laser beam was directed at the lights, causing them to change behavior, which the author suggests might be explained by the laser interacting with the energy of the 'earthlight' itself. The document concludes by providing a series of maps detailing low-flying hang gliding sites across the United Kingdom, which appear to be included as reference material for airspace management or identification purposes.
