At 7:15am on June 30, 1908, a blue-white fireball flew over the remote region of central Siberia near the Stony Tunguska River and exploded with the force of a 10- to 15- megaton hydrogen bomb. The explosion wiped out approximately 60 million trees across an area of 2,000 square kilometers. Witnesses from hundreds of miles away saw an immense pillar of fire and heard thundering claps. Those closest to the blast were deafened by the noise and knocked off their feet when the thermal wave swept through the area. Miraculously, no one was killed.

Since then, the scientific community has come up with a plausible reason for the blast––a mid-air comet or meteor explosion. Despite this, there are those who believe that the explosion was caused by a very large UFO, although there was no evidence of spacecraft debris. Scientists did find rocks embedded in the ground and the trees that are consistent with the material found in meteorites.

What you’re looking at is not an upside-down rainbow or a clever trick from the photographer. This extremely rare phenomenon was caused by sunlight shining through a thin, invisible screen of tiny ice crystals high in the sky. Andrew G. Saffas, a Concord artist and photographer, saw the colorful arc at 3:51 p.m. on January 13th while having a family party. It lasted an hour, long enough for him to grab his camera and shoot many pictures, before it disappeared. This is one of the shots he took.

At approximately 4:30pm on November 7, 2006, a United Airlines employee witnessed a small, round disc-shaped object (roughly the size of a US quarter) hovering over Gate C17 at Chicago’s O’Hare Airport. The employee had been working on the ramp and happened to look up in time to see the metallic looking disc spinning directly over his head. He called his supervisors, who went to his location and watched the object spin for approximately two minutes.

Then, they watched it shoot straight up through solid clouds, which were hovering at 1,900 feet at the time. Approximately a dozen witnesses saw the incident, including the pilot and co-pilot of Flight 446, bound for Charlotte, NC.

Did the United Airlines employees witness a UFO sighting? Or, was this a reflection of light off the low-lying clouds, as the FAA is suggesting? According to them, the air traffic controllers didn’t see anything unusual on their radar screens. They aren’t investigating any further.

Crop circles have appeared throughout the world long before the infamous Dave and Doug duo began misleading the world about their grain-stomping pranks in 1991. The earliest accounts of crop circle formations were documented by Robert Plot, then curator of the Ashmolean, in 1678. Dozens of eyewitnesses reported these crop circles forming in a matter of seconds as early as 1890.

To date some 10,000 crop circles have been catalogued worldwide, and their anomalous features continue to be irreplecatable: plants bent an inch above soil and gently laid down in geometrically-precise patterns with no physical signs of damage, light burn marks at the base of stems, altered cellular structure and soil chemistry, discrepancies in background radiation, alteration of the local electromagnetic field, depletion of the local watershed, and dowsable, long-lasting energy patterns, not to mention measured effects on the human biological field. So much, then, for two guys and a piece of wood. But thanks to a virtual embargo on research coverage throughout the media, a popular myth has developed that all crop circles have been nothing more than a prank with a plank.

The above quote was taken from an extract of Secrets in the Fields. Scientists believe that they may have the answer to the cause of these crop circle formation–sound. Click on the links to read about their discoveries.

Many witnesses have described hearing a trilling sound, followed by a sudden stillness in the air. They would watch the wheat heads bang together, despite this stillness. Then a whole section of crop flattens to the ground in a spiral pattern in less than fifteen seconds.

Can you imagine being there and watching this happen?
