UFOs are getting dangerous and there is concern that a hostile foreign power may have advanced technology.
https://www.thedrive.com/the-war-zone/28231/multiple-f-a-18-pilots-disclose-recent-ufos-encounters-new-radar-tech-key-in-detection Since the US Navy has upgraded their war fighting sensor technology including stealth penetrating radars and infrared sensors, the detection of UFOs has gotten to a crisis level. This period of increased UFO sighting frequency began with the so called Tic Tac incident on the west coast of America (see Wikipedia: USS Nimitz UFO incident - and the official report: https://media.lasvegasnow.com/nxsglobal/lasvegasnow/document_dev/2018/05/18/TIC%20TAC%20UFO%20EXECUTIVE%20REPORT_1526682843046_42960218_ver1.0.pdf Summary here are the 'Key Assessments' The Anomalous Aerial Vehicle (AAV) was no known aircraft of air vehicle currently in the inventory of the United States or any foreign nation. The AAV exhibited advanced low observable characteristics at multiple radar bands, rendering US radar-based engagement capabilities ineffective. The AAV exhibited advanced aerodynamics performance with no visible control surfaces and no visible means to generate lift. The AAV exhibited advanced propulsion capability by demonstrating the ability to remain stationary with little to no variation in altitude transitioning to horizontal and/or vertical velocities far greater than any known aerial vehicle with no little to no visible signature. The AAV possibly demonstrated the ability to 'cloak' or become invisible to the human eye or human observation. The AAV possibly demonstrated a highly advanced capability to operate undersea completely undetectable by our most advanced sensors. Now it's happening on the East Coast, the occurrence and subsequent reporting by US Navy pilots of UFOs has gotten to the point that possible collisions with these unidentified objects are becoming a serious safety issue for the fleet. Numerous gun site videos have been publicly released by the Navy that show these unidentified objects on the threat tracking screens of Navy aircraft. The New York Times writes: The pilots began noticing the objects after their 1980s-era radar was upgraded to a more advanced system. As one fighter jet after another got the new radar, pilots began picking up the objects, but ignoring what they thought were false radar tracks. “People have seen strange stuff in military aircraft for decades,” Lieutenant Graves said. “We’re doing this very complex mission, to go from 30,000 feet, diving down. It would be a pretty big deal to have something up there.” But he said the objects persisted, showing up at 30,000 feet, 20,000 feet, even sea level. They could accelerate, slow down and then hit hypersonic speeds. Lieutenant Accoin said he interacted twice with the objects. The first time, after picking up the object on his radar, he set his plane to merge with it, flying 1,000 feet below it. He said he should have been able to see it with his helmet camera, but could not, even though his radar told him it was there. A few days later, Lieutenant Accoin said a training missile on his jet locked on the object and his infrared camera picked it up as well. “I knew I had it, I knew it was not a false hit,” he said. But still, “I could not pick it up visually.” At this point the pilots said they speculated that the objects were part of some classified and extremely advanced drone program. But then pilots began seeing the objects. In late 2014, Lieutenant Graves said he was back at base in Virginia Beach when he encountered a squadron mate just back from a mission “with a look of shock on his face.” He said he was stunned to hear the pilot’s words. “I almost hit one of those things,” the pilot told Lieutenant Graves. The pilot and his wingman were flying in tandem about 100 feet apart over the Atlantic east of Virginia Beach when something flew between them, right past the cockpit. It looked to the pilot, Lieutenant Graves said, like a sphere encasing a cube." The question then that begs to be addressed: Do UFOs exist? This is a case where there is good observational evidence but no possible applicable science to explain multiple reliable observations. Let's roll in some physics. How does science handle this situation? I have my posit and its not extraterrestrials.
