Many of us who follow and study UFOs are aware of their ability to disappear not only from radar but from visual contact as well. Cmdr. David Fravor claimed to have a TicTac directly in front of him which suddenly disappeared. Not flew away, but disappeared entirely. We have two pages on our website, ‘The Screamer’ and ‘The Unseen’ dedicated to this extraordinary phenomenon in our ‘Members Only’ section. Oftentimes UFOs are seen and not heard, in the case of these two pages, these UFOs are heard and not seen and you can learn more about sonic booms associated with this unusual phenomena from author Micah Hanks writing for The Debrief HERE.
