Do the underwater USO, or even the aerial UAPs, make a sonar boom or sonic boom when they move so fast in water or air? If not, then how? Tim Gallaudet and other whistle blowers have never indicated that a sonic boom or sonar boom is accompanied with the movement of these NHI craft. What is the scientific hypothesis to explain the lack of sonic or sonar?
