Angel Grass - Published Explanations

Published Explanations

Explanations based on known phenomena include:

• Some types of spiders are known to migrate through the air, sometimes in large numbers, on cobweb gliders. Many cases of angel hair were nothing other than these spider threads and, in one occasion, small spiders have been found on the material. Linyphiidae spiders frequently cause showers of gossamer threads in England and the Northern hemisphere. Australia and New Zealand have frequent cases, caused by several native species of spiders and by some introduced species of Linyphiidae.
• Atmospheric electricity may cause floating dust particles to become polarized, and attraction between these polarized dust particles may cause them to join together, to form long filaments.
• On two occasions a sample was sent for testing once on the 13 of October in 1917 a sample found at Cova da Iria was sent to Lisbon and on October 17, 1957 another sample found at Cova da Iria and examined. The analysis of this proved to be natural consisting of white flakes. When put under a microscope it was found to be a vegetable product not animal.

Non-scientific explanations based upon a belief in Unidentified Flying Objects include:

• Ionized air may be sleeting off the electromagnetic field that surrounds a UFO.
• Excess energy converted into matter.
• The usage by UFOs of a G-field would cause heavy atoms in ordinary air to react among themselves and produce a kind of precipitate that falls to the ground and disappears as the ionization decreases.
