Around 9pm local time on Saturday, March 16th, 2019, an air ambulance helicopter was flying roughly 15 miles west of central Last Vegas when something odd caught his aided eye. During an exchange with an air traffic controller, the pilot of Mercy Air 21, an Agusta 119 Koala helicopter, noted spotting an unidentified object some distance from his position and only he was likely able to see it in the darkness as he was wearing night vision goggles (NVGs). The controller responded that he had nothing on radar in the area where he was seeing the object, but when he heard the pilot could only see it through his NVGs, he responded with amazement.
