Cigar over Gulf of Mexico, FL

The report, as filed

On 5/11/16, on a flight from Atlanta to Cancun, we were at cruising altitude possibly over the gulf of mexico when a large, chrome-colored, cigar-shaped object passed us going in the opposite direction. The object seemed very close (maybe 100 yards) and pass us horizontally and at the same altitude. Oddly, the object seemed to pass by very slowly, more slowly than you might expect to pass another flying object going in the opposite direction. It was clear that the entire object was metallic (chrome-colored) as it reflected against the bright sunlight and was emitting huge plumes of white "smoke" similar to an old train steam engine. From my seat, the object was visible for about 5-10 seconds. I noticed that there was no vertical wing, no windows, no markings, or any other indication that it was a plane, but I assumed it was a plane given the plumes of smoke coming out of its rear so I didn't give it much thought about it at the time. Note too that ! there was no indication from any other passengers (except my fiance who was seated at the window and was the one that alerted me to the object)or crew members that they saw anthing unusual. Later that day and the days to come, I became more and more bothered about what I saw and decided to do a Google search a few days later on "metallic UFO cancun" which resulted in images and videos of "cigar-shaped" UFOs that look very similar to the object that I saw. Unfortunately, I did not take any pictures of video of the incident, but will provide a rendering of what I saw.
