Sighted a large rectangular craft hovering above our property on a clear moonless night and viewed it for about five minutes.

It was a clear dark moonless night with a full complement of stars. We live on an 8-acre rectangular property with an old abandoned house about ¼ of the way up the property, a new house we built about 1/2-way up the property, and another 4 acres of woods at the top of the property, which slopes upward most of the way. I went to check the mail and was walking up the driveway and was in front of the old abandoned house when I realized that something was blocking out the stars above me. It was a rectangular-shaped craft about three times as long as it was wide, and it was just hovering there with what I perceived to be its “nose” pointing due east. There was a red light and a blue light visible on the bottom of the craft; not prominent but large enough to be easily seen. It also had what looked like two “headlights” on the nose of the craft. They reminded me of headlights because they emitted a clear white light such as headlights emit. I recall that I wasn't at all afraid, just intensely curious about what it could be. I was standing directly under it and it seemed immense, yet there was absolutely no sound coming from it. It just hovered there. We have tall fir trees around our property, which the craft was about 50' above, so I guesstimate that it was probably about 300' in the air. I stood there taking in the sight for what seemed like a very long time, but in reality it was probably only about five minutes. Then, suddenly, it started moving slowly eastward and only seconds later it accelerated so fast that there was a “whoosh” and...it was gone. It just disappeared from view.
I am a white male who was 75 years old at the time of the sighting. I have a double degree in economics and business management, and worked in management at not-for-profit organizations and the United Way for most of my business career. I officially retired about five years ago, but still help friends and family with accounting and business-related issues. My wife is an OB/GYN Nurse Practitioner who is five years younger than me. She had her own practice for many years and also worked under contract with medical clinics as an Independent Practitioner. We have lived in the Newberg, OR are since 1996 and on this property since 2004.
