[meteorite-list] Trajectory of Chelyabinsk meteors

Here is an interesting approach to calculating the trajectory by looking
at videos of moving shadows:

These calculations by Stefan Geens ("I am not a trained scientist") seem
to fit well with the observation of an impact in Lake Chebarkul.

There's also a simple map:
