The Tunguska event on June 30, 1908 has come to be known as the "Russian Roswell," with almost as many wild theories circulating about it as about the 1947 incident. Like this one:
Dr. Yuri Labvin, president of the Tunguska Spatial Phenomenon Foundation, insists that an alien spacecraft sacrificed itself to prevent a gigantic meteor from slamming into the planet above Siberia on June 30, 1908.Of course, scientists scoff at this kind of thing but still have no definitive theories as to what caused it, only their own speculations. The latest speculation is making the rounds today, as we see in the Space.com headline, "Space Shuttle and Strange Clouds Key to Mysterious 1908 Explosion:"
Most scientists think the blast was caused by a meteorite exploding several miles above the surface. But Labvin thinks quartz slabs with strange markings found at the site are remnants of an alien control panel, which fell to the ground after the UFO slammed into the giant rock.
New evidence from an unlikely source -- water vapor in the exhaust plumes of space shuttles launched a century later -- points to a comet. The potential solution comes courtesy some strange clouds that scientists have only recently begun to understand.The article goes on to add that scientists have been able to observe these clouds during a shuttle mission:
Noctilucent clouds are brilliant, and visible only at night. Made of ice particles, they are Earth's highest clouds...in fact, space shuttle launches have been found to cause or enhance the formation of noctilucent clouds.
Noctilucent clouds were tied to the launch of Endeavour (STS-118) on Aug. 8, 2007. And high-altitude clouds were detected over Antarctica shortly after the fateful launch of Columbia, which along with its crew was lost during re-entry. Columbia's plume was 650 miles long and 2 miles wide and reached Antarctica in three days.OK, help me out here, I'm not a scientist. We're being told here that the Tunguska event was the result of a comet and not an exploding spaceship.
And what are we being offered as the observable evidence of this theory?
An exploding spaceship.
