Just got done getting my SW flights changed...
Right as I got done I hear very loud booms, several in a row... Nothing like thunder, explosions... Its -6 deg out so fireworks are pretty much ruled out... We leave not to far from an AF base so start wondering if there is something going on. So I run out to the back yard to see if I can identify it any better and then happen to see several objects in the air with flashing lights. Seconds later more appear but WAY to close to be commercial. I call DW out and when I turn around the number increased a few more. We've had a lot of drones around the past few weeks that are large (Like 6' wing span) with sightings all over NE and CO that no one is fessing up to knowing anything about... According to some posts on NextDoor sounds like a dance studio put on a firework show for a girl that passed away this past summer as today would have been her birthday.
UFOs Drones are still unknown.
