Strange streak of light apparently releases bright object over Red Springs

This is a time lapse of some night photography that Black Bulldog Photo did a couple of months ago and it shows a strange streak of light apparently releasing a bright object. 


Immediately after the streak of light, the second object appears from behind the top of the mountain, slowly descending and although the first object looks like a meteorite, it does not yet explain the second object. 

Since he images were taken at Red Springs, just west of Las Vegas facing Area51, the photographer wonders whether it was a launch of some sort or not.
