Fast Moving Triangle Craft - Two EventsAt about 9:15 pm on November 7, 2015, I decided to sit in my hot tub. About an hour later I witnessed a silent black triangle fly over the tree in my backyard continuing over the neighbor's house - it was coming from the northeast and flying to the southeast. I believe it was between 10:15 and 10:30 pm, I did not look at the time on my phone until 10:44 because I was collecting my thoughts on what I had just witnessed. The object had flown over in the 11 o'clock position and was about the size of my fingers at arm's length or about 3 1/2 inches. It was an equilateral triangle, silent, black with pointed  corners, and the two leading edges were glowing. About 45 minutes later probably between 11:00 and 11:05 pm - (I didn't look at the time until 11:09 pm because once again I was collecting my thoughts.) I saw two of what I assumed were the same object that I saw earlier. They were flying north to south in a side by side formation. The two leading edges of both objects were glowing and this is what I was focused on. I was trying to figure out how many "lights" there were. The glow was very, very dim. There were many points of light on the edge and brightness was not consistent nor was the spacing even. Having experience working with plasma, it appeared to be more of a plasma glow. By 11:15 pm I had decided that was enough of that for one night and I was in the house.This would be the first time that I have experienced anything of that nature. It freaked me out to the point that I slept with the  lights on for about a week. I had just set up the hot tub towards the end of summer and was spending one to six hours in it per night or about 20 to 30 hours a week. I had always believed that only a certain type of person saw such things and that most could be explained. My thoughts are now inclined to believe that of you spend enough time outside - you will eventually see something.
