3 V shaped amber lights over Lakeland Hills moving north then went west and gone past the horizon in seconds

On the night of May 17th, 2019, at approximately 23:43, I was outside on my back deck in the Lakeland Hills neighborhood.  I looked to the west to watch some of the planes taking off to the south from Sea-Tac Airport, when 3 amber/orange colored lights in the shape of a "V" came over the top of my house at probably the same altitude as an approaching aircraft would.
The lights moved across the sky very slowly, with the lights remaining constant; no flickering, on/off, pulsing, etc.  After roughly 1.5 minutes moving from south to north, they abruptly disappeared in what I would estimate to be probably the Kent or north Auburn area.  
I didn’t know what to make of it until about 5-10 seconds later the lights returned moving west over the top of the Sea-Tac airport at an unfathomable rate of speed, and within 1-2 seconds the lights disappeared past the horizon.
