6 came in view one then another, straight path S/E to N/W red/yellow glow, at a distance they at times seem to disappear and return.

I was going to check my mailbox, at 20:35 or so I turned to call my dog and observed an odd light in the sky (initially one light). The objects were triangular (appearing like an upright Conquistador Hat). They were lit up like a glow (not lights like a conventional aircraft). They silently moved from southeast to northwest direction. They were lit in a red/yellow color but seem to have a dark metallic boarder at the lower base. There were a total of 6 that came into view one at a time approximately 2 minutes apart on the same path, very silent, not a sound. Once they got miles pass, they seem to elevate and vanish (two of them vanished overhead and returned then disappeared miles away). I called a neighbor to come out and see them, they saw them as well. I videoed a few of them, then (and I don’t care who believes it) the video recording stopped and the video option on my iPhone was gone (all other options were available). After the last craft went over I waited for any others then got my mail, went in the house turned the camera back on my iPhone and the video option was back available. About 15 minutes later I went outside and there were helicopters to my Northwestern sky. I am a retired Army Senior Non-Commissioned Officer.
