[Utah-astronomy] What is it? (another one)

Just before Ed posted his "What is it?" message I received another such query from Dan Pope at channel 4. He relayed a message from a lady in Vernal who took these pictures around 5:15 pm the evening of this past Sunday the 4th. http://www.trilobyte.net/paw/temp/WHATISIT.JPG The object was in the western sky, moving west. The pictures do not show it very well but she said the object was U shaped. She estimates she watched it for about 3 minutes before it passed over the horizon. The only thing I can come up with is a high altitude jet reflecting sunset red off its belly and the U shaped extensions being short lived contrails. Any other guesses? Patrick
