This is some of the most extraordinary and dramatic video you might ever see, because it's so rare.
A meteor crashed into central Russia today, injuring up to 950 people. In the video, you can see a bright fireball streaking through the sky toward the earth.
Reports say when it hit, there were loud bangs and shockwaves that blew out windows and shook buildings. Most people who were hurt suffered cuts and bruises from flying debris.
Polina Zolotarevskaya was in the city of Chelyabinsk, about 1,500 kms outside Moscow, where the meteor hit. She told BBC News...
"It was quite extraordinary. We saw a very bright light and then there was a kind of a track, white and yellow in the sky."
"The explosion was so strong that some windows in our building and in the buildings that are across the road and in the city in general, the windows broke."
Officials say a large meteor partially burned up in the lower atmosphere, with fragments falling toward the earth.
Another person in Chelyabinsk, Sergei Serskov, told the BBC the city felt like a "war zone" for about half an hour.
"I was in the office when suddenly I saw a really bright flash in the window in front of me," he said. "Then I smelt fumes. I looked out the window and saw a huge line of smoke, like you get from a plane but many times bigger."
Another resident of Chelyabinsk Sergey Hametov told the Associated Press "There was panic. People had no idea what was happening. Everyone was going around to people's houses to check if they were OK."
"We saw a big burst of light then went outside to see what it was and we heard a really loud thundering sound,"
Russian President Vladimir Putin promised "immediate" aid for the people affected by the meteor strike.
Another witness Viktor Prokofiev told Reuters "It was quite dark, but it suddenly became as bright as if it was day... I felt like I was blinded by headlights."
The Russian Academy of Sciences estimates the meteor weighed about 10 tonnes and entered the Earth's atmosphere travelling at 54,000 km/h (33,000mph).
Officials say most of it would have burned up about 30-50km (18-32 miles) above the ground.
