Meteorite crash in Russia

"Experts say the explosion took place 5 km above the ground" - judging from the videos I have a feeling time to reach the surface was much longer than 15 seconds (plus people had to get the cameras and switch them on, which adds at least 10 seconds more). But then I have not tried to measure it.

A terrifying meteorite shower left more than 950 people injured, buildings devastated and the mobile network wiped out when it hit Russia this morning.

Brightly burning rocks could be seen for miles as they crashed at around 9.20am local time and one bystander described it 'like a scene from the Armageddon movie.'

The meteorite is believed to have landed in a lake near Chebarkul, a town in the neighbouring Chelyabinsk region.

I don't think its coincidence, suppose the asteroid was at one time a larger mass and collided with another asteroid causing many smaller fragments to travel along the same trajectory. I'd expect more meteors during and after the event too.

Hundreds reportedly injured!

NASA spokesman Steve Cole told CNN that scientists had determined that the Russian meteor was on a very different trajectory from the asteroid.
"They are completely unrelated objects -- it's a strange coincidence they are happening at the same time," he said.

On a related note, a colleague here noticed that the video times are different. Some I'm wondering if some old videos have also been mixed in with the latest actual video.
