In mid-2014, during training flights off the coast of Virginia Beach, Virginia, F/A-18 pilot and U.S. Navy Lieutenant Ryan Graves began to notice something strange. The radar returns looked offphantom blips moving with unfathomable speed and precision. The objects on one occasion finally came into view. Graves reported seeing a dark gray or black cube inside a clear sphere, between five and 15 feet in diameter, coming within 50 feet of their jets. Over the next year, Graves's squadron recorded sightings of unidentified objects almost daily. Sometimes the objects flew in loose formations. Other times they traveled alone. They had no exhaust, no visible propulsion, no wings. Some of these craft"now classified as UAPs (unidentified anomalous phenomena)"appeared to be capable of transmedium travel, meaning they are able to move from air to sea without slowing, splashing, or emitting heat. They challenged every assumption held by aerospace engineers and radar operators. Since at least the 1950s, military sources have reported strange objects plunging into the ocean"what they call USOs (unidentified submerged objects). Today Graves is one of the most vocal advocates for UAP transparency. He's the founder of Americans for Safe Aerospace, the largest UAP-focused pilot safety initiative in the world. He doesn't claim that these craft are alien, but he's certain that they aren't using known human tech.
