Looking in the direction of cassiopeia, Two formations flew from west to east quickly.

Looking in the direction of Cassiopeia at 10:12 PM with a completely clear sky I witnessed at least 5 lights arranged in a V almost half circle formation with an additional 2 lights; one taking a position in the front moving from left to right (north south) and back to the other end of the formation whilst the other light following in the rear copied this motion but in an opposing manner ( if the front light was at the north end the rear would be in the south) . The manner in which these 2 oscillating light flew was too perfect, they did not alter their path. Only a guard of the tomb of the unknown soldier can move like that. This formation flew very quickly from west to east rapidly reaching the horizon. Before the 1st formation disappeared from sight a second formation of at-least 5 lights in a more compact V formation entered the sky at the same location as the initial formation and followed the same path across the sky in-front of cassiopeia until reaching the horizon. The speed at which these lights flew across the sky exceeds any ISS transit and Satellite I have seen in the night sky. The best way to describe the individual lights is to compare them to the stars in the background night sky, if they suddenly stopped moving they would look like new stars in the sky. My thoughts, 1st wave aliens, second wave maybe fighter jets. This happened at a very popular beach and the movement was too quick and and lasted too long for me to be the only one to witness it, I can only hope. Thank you.
