USS Omaha incident
According to Corbell, the footage was filmed on July 15, 2019, at approximately 11 p.m. PDT, from within the USS Omaha's Combat Information Center, near the coast of San Diego. Radar images of the UFO show a solid ball, measuring about 6 feet (2 meters) in diameter, flying at speeds of 46 to 158 mph (74 to 254 km/h). Its flight lasted over an hour, culminating with the sphere vanishing beneath the waves. No wreckage was found at the location where the object went down.
"A submarine was used in the search and recovered nothing," Corbell wrote. "We do not know what, if anything, the Navy or Pentagon might be willing to say about the USS Omaha incident, but we are confident the incident is a legitimate mystery and look forward to whatever information might be forthcoming," he wrote on Instagram.
