It's not a single event but a wave trailing the moving object.

I understand what a sonic boom is.

A sonic boom does not create a brilliant flash of light that is many times brighter than the sun. This flash is plainly visible in most of the videos and clearly represents an enormous release of energy.

A sonic boom also does not occur at a single point creating outwardly radiating blast damage like the Tunguska event did. I have not seen evidence of outwardly radiating damage from this event yet, but I'm guessing it is there although less evident since it appears this event was not powerful enough to knock down trees.

The thing exploded. While I'm sure there were sonic booms created by the thing moving fast through the atmosphere before that, it seems pretty obvious that most of the energy in the shockwave that knocked out windows and damaged buildings came from the explosion, just like the Tanguska event.

I was just asking what causes it to explode. The link I provided earlier has some plausible explanations.

Here's the story of the Tanguska event, which was also an explosion at low altitude.

Planet Earth is Protected by The Atmosphere. IF not...Like the Moon which is pelted by all space debris...tons of craters

When this lil thing was traveling 33,000 plus miles per hour..and enter Earth Atmosphere...IT created...Heat...and that heat...broke apart this lil meteor.

The trail of smoke..was the meteor breaking apart...and BOOM! There you go.

Remember when The Space Shuttle Columbia...it burned up in the Earth's Atmosphere and caused a sonic boom, it was not traveling as fast as the meteor, 17,500 mph.

So you're saying that the Russian meteorite was 50 feet in diameter BEFORE it entered the Earth's atmosphere, and created an ice whole crator larger than 50 feet in diameter AFTER it exploded and hit the ground?  A metorite blazing thru the atmosphere would lose a SIGNIFICANT amount of it's mass while burning up and before making impact.  That's what makes sence to me...

Yahoo:

The Russian meteor explosion over the city of Chelyabinsk, on Friday (Feb. 15), injured more than 1,000 people and blew out windows across the region in a massive blast captured on cameras by frightened witnesses. Friday afternoon, NASA scientists estimated the meteor was space rock about 50 feet (15 meters) and sparked a blast equivalent of a 300-kiloton explosion. The energy estimate was later increased to 470 kilotons.

But late Friday, NASA revised its estimates on the size and power of the devastating meteor explosion. The meteor's size is now thought to be slightly larger — about 55 feet (17 m) wide — with the power of the blast estimate of about 500 kilotons, 30 kilotons higher than before, NASA officials said in a statement.

That's cuckoo alright.

But it's not the only one. There's newspaper stories now saying it was man made. Unfortunately those papers are coming out of the USA and the UK

It's a sad day for the forum when first rate material like this goes completely ignored.

If you don't attach a stupid picture to it, people on the Interzone don't see it
