UFO Sighting in Montana on June 7th 2015 – Soft white glowing light with no aircraft warning lights flew slow and steady untilout of sight

I was watching the sky as I do most nights. My view to the north is mostly open sky. An object caught my eye when I was looking at Venus. The object appeared to be an aircraft as it displayed flashing lights. But upon closer inspection I could determine the craft had three RED lights that were flashing . This craft was headed in a NWN direction. I observed it for about 30 seconds when I noticed another object/light. This one was closer to me by about half the distance of the other . This light was not sharp light Venus or the other visible stars. It had a soft like glow and what hit me right away was it had no flashing lights on it at all. I watched it move in an easterly direction until it went out of my line of sight. I watched to for about 30 seconds. I grew up in a town with two air bases. I am familiar with many types of aircraft both military and civilian. In fact it is my hobby to study military aircraft. I am no expert but I have build almost every military aircraft model ever made !!!!! The point is ....these two did not resemble anything I have ever seen. And while they both were just lights the lights each craft displayed were not typical of current aircraft.
