Other over Chandler, AZ

The report, as filed

I am a truck driver who was driving in the state of Arizona on interstate 10 east bound between mile marker 181 and 182. I initially noticed one circular bright light in the sky swooping down over a field then back into the sky at a high rate of speed. As I noticed the light coming back around repeating the the same motion, I was closer to the object than before. As I noticed the object swoop down almost touching the field only one light was on, then a second, and then a third circular light appeared. Each light was evenly spaced in a straight line. As this was happening, I turned my head out the window and looked back as the object was ascending back up toward the sky. With the lights pointing up I was able to see the shape of this object. The shape of this object resembled a large rectangular wing similar to a wing on an old time wwII plane. The side of this object opposite of the three lights had the middle part of this wing purtrud out in the center of the wing like a tab. So that side was not completely straight, The other side with the lights was straight with three large white circular lights in a row. I attempted while watching this to take a picture but was unable to while driving. I have never seen anything like this during my 15 years on the road as a truck driver and wanted to report this and hopefully get a logical explanation on what this may have been. I have a sketch of this object as well that I can mail to you. We spoke via telephone with the witness, and he seemed to us to be unusually eloquent in his description of the object, and quite sober-minded. We suspect that he is a highly capable, and highly reliable, witness. We have corrected the date to read July 14. PD
