According to unconfirmed reports, the meteorite was intercepted by an air defense unit …. A missile salvo blew the meteorite to pieces at an altitude of 20 kilometers, local newspaper … reported quoting a source in the military.
Vodka was probably involved.
This thing was moving at 30 km/sec in a crossing shot, but ICBM RVs enter the atmosphere at around 8 km/sec in a plunging shot (shotgunning terms). No way this thing was intercepted by an ABM.
What they probably meant to say was that defense radar/IR sytems detected or tracked it.
The regional Emergency Ministry denied that military air defenses were involved in the incident.
Less vodka was involved.
Regnum news agency quoted a military source who claimed that the vapor condensation trail of the meteorite speaks to the fact that the meteorite was intercepted by air defenses.
That, uh, that doesn’t even make sense.
One probably shouldn’t quote a Russian Army private coming out of the all-ranks club.

We can’t believe our own government how can we believe anything from Russia? Who knows all evil lurks in the heart of man?

Re: the “intercept” explosion
It looks sort’a like the Patriot/SCUD videos from the Gulf War, but it ain’t.
At 30 km/sec in the atmosphere, a rock-iron meteor gets whatchacal hot. The light you see is due entirely to temperature. High-altitude (low-density) atmospheric heating doesn’t melt or vaporize the whole meteor, just the surface, so it ablates (small surface bits break off, glow, and vaporize); but at some point, the temperature gets really high (time and higher air density) and the heat penetrates further, so the structural integrity of a thick-enough layer of material fails. Any gases may also reach high pressure. At that point larger amounts of material come off, and all these particles are exposed to the heating air, so that stuff goes super-bright, too. The newly exposed chunk is increasingly thermally shocked, so it begins to fail quickly in a cascading exposure of material to critical atmospheric heating.
You know, it goes *kablooie!*
If it happens quickly enough, this may produce a noticeable atmospheric shock wave. Any unvaporized pieces (now too small and/or too slow to go kablooie) hit the ground as meteorites.
Comet meteors probably fall apart sooner due to weaker structure, and they don’t produce iron chunks as meteorites.
(What? Discovery Chanel.)
Note: I did not use a meteorite-study-as-rockette-science pun … for good reason.

Easy one, Doug. Because God hates Russians, an he knows 11 time zones is a easy target……..

RUSSIAN BLACK HUMOR: One of the most popular jokes was that the meteorite was supposed to fall on Dec. 21, 2012 – when many believed the Mayan calendar predicted the end of the world – but was delivered late by Russia’s notoriously inefficient postal service.

Reminds me of the lightning-on-a-golf-course joke:
If you want to be safe, hold up a 2-iron, ’cause not even God can hit a 2-iron.
(What? Well that’s the Lee Trevino version.)

On looking at more footage, it’s clear that I neglected to comment on the coolest physicsology thing … the sonic boom!
Man, I loved those as a kid, back in the days when they could fly supersonic up in Michigan.
(What? Well, the AF prob’ly had a good window-replacement budget back then.)
