Yep. Another example turned up recently when the radar operator in the USS Nimitz CSG case going by the name of Trevor described the close-range gun camera footage that he saw of an intercept attempt, following highly anomalous radar returns that showed a number of targets that cruised south at 100 knots at an altitude of 28K feet - until the jet interceptors approached, and the objects dropped to a position just above the ocean in .78 second. That's an average speed of 24,000 mph. To put that in perspective, the speed of a bullet is about 800 mph - so we're talking about an object that can change position at 30 times the speed of a bullet and then suddenly come to a dead stop and hover mid-air. Trevor described the object in the optical video footage as a disc with a flat bottom and a domed top similar to these other reports and the Hannah McRoberts photo, and he described seeing the object execute seemingly instantaneous leaps between positions on the optical gun camera video.
So if the object in her photo is in the class of device that Trevor saw on the gun camera video and his radar screen, then it's perfectly reasonable to consider that these objects commonly leap between positions at astounding speeds, so the object she photographed may have only been visible for a fraction of a second when she snapped the photo, explaining why she never saw it with her eyes.
Interesting and understandable, but just a word of caution about many in this field who like to add speculation to speculation and before you know it zero plus zero equals something other than zero.
