While sky-watching outdoors, I observed numerous aircraft passing overhead. As I scanned the sky through the viewfinder of my Nikon P900 camera, I focused on a lingering contrail left by a passenger jet. Suddenly, an anomalous craft streaked across the frame. I reacted instinctively, pressing the shutter just in time to capture the mysterious object in a single image before it vanished.

I looked around the sky, but I was unable to see it again. I immediately went inside to look at the photo on my 4k TV and get a better look at this anomalous object.
