It was 12:20 in the afternoon. It was partly cloudy but there was lots of blue sky. I was working in the yard when I heard a plane flying over head. I looked up and saw the plane. It was a big plane like a 747 or something and it was flying at very high altitude, so it was quite small. However I noted that it was being shadowed by an long narrow craft. It might have been tube shaped. It was light colored like silver. It was about 1/3 the size of the plane. The plane was heading East or Southeast and the tube shape was off the right wing of the plane, just back from the nose and quite close. It wanted as the both flew above a cloud and came out the other side. Ran inside and sent my husband a text, to save the time and date, and I reported this to the NUFON website. I just read, from your website, that someone else from the Spokane Valley saw the same thing on May 23rd. That is very interesting.
