Cigar shaped object flew over my parents home in Pendleton, Oregon

About 2 years ago during the summer I was visiting my mom in Pendleton, Oregon (I live in Stanfield about 22 miles from Pendleton), and we (my family) saw these two lights one in front one in back. At first I thought it was just two planes.  My brother pointed out that they were flying in perfect alignment and so we waited to see if when it flew over the stars, if it covered the stars, which it did.  I did not go in to get a camera or anything because I was in shock and afraid I would miss something.  Anyway, it flew along then suddenly shot out a flair or something then it was gone. I called the airport tower which told me that their last flight was well earlier.  I called the National Guard Base who told me they had no flights out at that time.  I drove to the airport to look for incoming planes, and I did see some 20-something people out by the hangers, so maybe it was two small planes, but it made no noise, and samll planes usually make a lot of noise, and it did cover the stars. The object seemed to be cigar shaped with a light on each end. All the neighbors were out, but no one was looking up and no one else in Pendleton ever reported a thing.
