“A riveting insider’s account—and a must-read for entrepreneurs and PR pros navigating the storm between innovation, tragedy, and media firestorms.”
—David Meerman Scott, Bestselling Author, The New Rules of Marketing and PR

—Dr. Alan Stern, Planetary Scientist, Commercial Astronaut, and Titanic Explorer

—Rick Tumlinson, Founder, SpaceFund and EarthLight Foundation
“After hearing so much about the importance of safety from my father throughout all his submarine exploration, I was in shock to learn about the Titan disaster. Thanks to this book, we will finally understand what happened!”
