John. Here is how erroneous stories get started and spread across the globe.
The following is copied and pasted from a quote in your article.
(People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt a shockwave, according to a Reuters correspondent in the industrial city 950 miles east of Moscow.”)
They might 'See a bright light, hear an explosion and then feel a shock wave'. but it would have to be in that order. Journalists mis report facts all the time. I used to work as an investigator and the one source you could never depend on for the truth was the media.
