Bob McGwier, a professor at Virginia Tech and with the Institute for Defense Analyses, was carrying out classified work on the USS Hampton submarine when he heard the sound of 'something whizzing by.' The onboard sonar determined the unidentified submerged object (USO) was traveling through the water faster than the speed of sound, he has calimed. Such speeds underwater should have crushed the submarine, according to McGwire, but he said it was as if they were standing still. McGwier said he urged the naval team to report the encounter, but they determined it would hinder the mission. The strange incident happened in the late 1990s, but McGwire recently came forward with the story on the YouTube channel UAP Society, where he wanted to 'blow the whole thing wide open.' The USS Hampton is limited by how fast it can travel due to the incompressibility of water in front of it, but the USO 'blew by' the sub. 'A person with knowledge of onboard systems' who was likely monitoring the sonar tech is said to have announced that something just soared past the submarine faster than the speed of sound, McGwire said during the YouTube interview. Sound travels faster in water, about 3,330 miles per hour because the liquid is about 1,000 times denser than air. The only manmade object comparable would be Russia's Shkval torpedo, but this can only hit speeds of 230 miles per hour.
