Possible UFO snapped over the Airport of Cancun

On September 7, 2004, a man was inside the airport of Cancun, Mexico, while he saw a weird object in the sky. He caught a picture of it. Meteore or UFO?

Witness report:

This photo was taken before boarding the flight back home on the above date and only noticed the object in the background sky above the plane when looking at the pictures back home as my focus was on the plane at the time. I'm presuming it's probably a meteorite but always wondered as it does appear to have a solid structure next to the light but this could just be a vapour trail or something?

I did send it somewhere else about 10 years ago but never heard anything back and the recent boom in UFO related events reminded me of this. So will let you have a look and see what you think.
