Unseen UFO caught in El Paso, Texas

On May 2, 2015, several friends were four wheeling in the area of El Paso (in Texas). During this journey, one of them has caught an unidentified flying object. No one has seen it. So, this UFO was no visible to naked eye and noiseless.

Witness statement:

Myself and some friends were 4 wheeling in the Oro Grande mountains right by the military site and once we reached the top of the mountain I took several pics and didn't realize I had captured this UFO until later on at night. We did not see anything in the sky or hear anything once the jeeps were turned off, it was dead silent when I took the pics. There wasn't anything flying around us at any time. My guess is I just happen to take this one pic at just the right time.
