People are freaking out over this bright light that appeared in the sky over the west coast
According to multiple reports, the light appeared to be trailing an object before eventually burning out. It could be seen from San Diego to the San Francisco Bay Area. Local news outlets have suggested the light could be the result of a meteor shower.
Similar occurrences have been noted when the US Military conducts exercises in local airspace. Reuters reported late Saturday afternoon that nighttime flights into and out of Los Angeles International Airport would be diverted away from airspace over the Pacific Ocean for precisely that reason.
The military and FAA usually do not disclose the nature of the exercises, and did not comment for Reuters, but the wire services reports that airspace over the Pacific Ocean was "activated" Friday night for the military activity. It's expected to remain off-limits to other aircraft until Thursday.
