Testing long range focus of 300 mm Nikon lens at high flying commercial airship, checking result found UFO near aircraft

I was testing the long range abilities (focus, resolution) of my 300mm Nikon lens in my back yard and took a Photo of a passing commercial aircraft.
Later when I reviewed the photo as I zoomed in to see how well I captured the moving aircraft I noticed a cylindric object with what appeared to be a white gas or smoke ejecting at 90 degree angle at one end. I checked the internet to see if there was other reports of such a sighting that day, and found there was a report in New Mexico from a commercial airline (American Airlines confirmed the radio transmission from Flight 2292 to Phoenix) that had seen a cylindric object next to there aircraft. I am attaching the photo I took, it is not altered, you will have to zoom in on the aircraft and the UFO will become obvious. I forgot about the photo until recently when I decided to find a resource that may have interest, so here you are.
