My sister ,my niece and my self were taking pictures of the moon.We were staying in a cabin 12 miles east of Forks Washington.I saw flashing red lights coming from below the moon in a westerly direction.I said look it's a UFO .(I am always joking about it because you never see one). They looked and it did look weird.At first we thought it was a plane then i thought it was two helicopters flying in formation ,but there was no sound .Then the whitish/blueish looking lights seemed to flash one after the other around the craft.The lights blinked so fast around that is just seemed to faintly show off it's triangular shape. It headed west coming from the east south east .We watched it glide through the air it banked and seemed to turn on its side then it came back towards the east it seemed to hover for a bit then it disappeared into the clouds when we saw it again it was heading west. It seemed closer .It then ascended up into the clouds and disappeared. I was so excited om my god it was pretty much the coolest thing i have ever seen in the sky.I was so stoked.My niece seemed excited and so did my sister. We were trying to theorize what it could be and one of our theories is that was military.Of course i want to believe it was extraterrestrial . I did take pictures and a video but you can't really see any thing.I heard a plane sound, then bit after that we saw one in the distance.It was a large plane booming sound not directly over head .It was hard to tell if the sound came from the craft because there was a lot of silence.
