Rectangle over Las Vegas (north of), NV

The report, as filed

I am camping on BLM land just North of Vegas at the road to Valley of fire. I heard a loud humming noise, and looked out my window and saw red lights flashing in the sky. About 300' to 500' above my RV rectangular shaped mass with red lights slowly floated by.I went outside the RV to watch it float by. I thought this might be a blimp but no blimp above the rectangle of red lights. I ran back into the RV to get my phone for a video. I shot two videos of the lights. The first also has the humming vibration in the audio. The humming noise did not match any airborne craft, plane, or helicopter I had ever heard. Plus it drifted very slowly. it was amazing how slow it could go and still stay elevated. I watched it as it floated towards the lights of Las Vegas along inter state 15 South. As it grew smaller 2 white lights which sounded like fighter jets went/chased in the same direction as the red flashing rectangle.Approx 8:55pm on 10/23/19
