IOW the "B-1" I also saw it before it became "public". Driving by myself up the I-15 just before it meets the 395 on my way to Lake Tahoe. Sometime in the late 70s. Around 5:pm and close to dark (winter). This "thing" (that's what I told my wife) came right over the top of my car. I pulled over, got out and watched it disappear. When I got to the resort I called her and told her I saw a UFO. She told me to quit drinking. So I immediately went down to the bar and began talking to anyone that would listen. One person said he had seen the "Lancer" (what he called the B-1)once before as well. I said yeah but this thing was like right on top of my car and he said that's what its designed for. When the eventual photos became public I knew that was what I had seen. Probably from Edwards as that wasn't that far away from where it "attacked" me and my little BMW.
