I wonder if the pin-speck technique could be used to reconstruct a 3d reconstruction of the Chelyanbinsk meteor:

1) There were huge amounts of recordings

2) It generated plenty of clear shadows (and presumable sun-shadows can be recovered as well)

3) For high intensity images, many cameras might decrease shutterspeed frame by frame, so each line is sampling a shorter period, thus a collection of cameras can be considered to perform random oversampling at a higher framerate (as some oscilloscopes do when not in single-shot mode)

4) The recordings are taken from many vantage points in a wide region, potentially allowing a 3d reconstruction of the meteor as it breaks up
