Here’s one interesting footage of a multiple bright objects flying across the sky above Las Vegas in Nevada. This was filmed on 9th December 2016.
Witness report: So last night I was walking in a local park in Las Vegas and i saw on the horizon 15-20 solid balls of yellow/orange light rising from ground level up to the clouds and then disappearing. They were probably 15-20 miles away so they weren’t paper lanterns as some have speculated. They also weren’t conventional aircraft as they were solid balls of light with no anti collision lighting.
