A lot of folks got startled freaked out on last Saturday night (November 7th). People from Los Angeles to Seattle and for quite some distance inland saw a strange light in the sky.
It turned out to be a test flight of a submarine launched missile (SLBM), apparently traveling roughly northwest from a launch point some distance west of Los Angeles.
Guess this is why the airspace over the Pacific Ocean west of Los Angeles was closed to air traffic for a week.
A number of pictures of the test flight have showed up in newspapers and on the internet. Most of them look like one of the two pictures shown here.
But this is the best picture I've seen of the event.
