In the news

i thought the big flash was it vapourising into nothingness but noise and light energy
the trail just seems to stop in most of the video's

it was only small one after all

not 100% about the one I psted, I don't speak russian, but guardian website seems to suggest craters are at least a possibility:

A meteor or meteors entered the atmosphere over the Russian city of Chelyabinsk early Friday and exploded in the sky, generating a shock wave that injured an estimated 950 people and damaged buildings. Itar-Nass news agency also reported damage in the nearby town of Cherbakul, where the military said a 20ft (6m) wide crater was found. Chelyabinsk is a city of about 1.1m people situated about 1,100 miles east of Moscow.
