I had no idea there was a place to share this kind of information. Anyway, my friend and I were playing foosball in Tacoma at "Games Unlimited" on 19th and Mildred. Oswald Airport was located at the same site, but had been closed and was being turned into a strip mall. Some of the old runway was still intact, so we'd use it as a bathroom (I was 16 at the time). I stepped onto the old runway to do my business and saw an orange sphere on the runway, behind some Scotch Broom (the runway was starting to get overgrown). When my eyes made contact with the sphere it turned from dull orange to bright orange. It flew straight up, and was out of sight in seconds.
