The Urals Impact
Feb. 15th, 2013 09:49 amOkay, so far information is not only fragmentary, but contradictory. Much of the confusion may be due to translation problems. It likely was a meteorite, but some of the specific descriptions seem more aircraft-like. One man interviewed by the BBC stated it had a tail "like an aircraft" which came off. Others also stated it was an aircraft or "like an aircraft." The statement that it was moving on a low trajectory at 30 kms (kilometers per second for the metric impaired) has been repeatedly made, with no attribution and no explanation of how the trajectory and speed were measured. There is a claim that it was intercepted by the local air defenses. However, the same source claims that the action by the air defenses explains why the object produced a vapor trail, which is nonsense. (Anything passing rapidly through the air with enough humidity present will create a vapor trail. A meteor will likely also produce a trail of vaporized material (that is, it's own outer layer heated and blown off by rapid passage through air) at least while still high and fast.) Reports repeatedly and emphatically declare radiation levels to be normal.
Some of this makes me wonder if a military aircraft perhaps carrying nuclear weapons had a catastrophic accident. A crash of a burning aircraft would produce most of the effects reported, especially if it exploded in the air.
Most likely, this was, indeed, a meteor, possibly from the same source as the much larger asteroid coming later today. Something this small could easily escape notice until it actually entered the atmosphere. However, people aware of the approaching body might be expecting a meteor and ascribe any unusual event in the air to that cause.
Addendum: Turns out this was a complete coincidence. The Urals impactor was from a different source, on a different trajectory.
