Last night, my wife, our friends, and i were in the back yard at 10:15 pm. we noticed a bright red/orange light on the horizon, which passed overhead in a sw to ne direction. as the first one was passing over, i noticed a second one coming from the same direction. i retrieved my binoculars for a better view. it was a dark, clear sky, and i could see no details - wings, rotors, etc. there was also no sound. a total of 4 - 5 identical objects passed over in the same direction. there is likely a very basic explanation for this, but i thought it best to report. a brief video of the event is attached.
