On March 10, 2019, eight of my colleagues and 149 passengers were killed instantly when their Nairobi-bound flight from Addis Ababa crashed six minutes after takeoff. Such a loss was staggering, incomprehensible. Relatives and loved were overcome with grief. The nation of Ethiopia came to a standstill, stunned with sadness and disbelief. The world mourned. We all wondered, “How could such a catastrophe have happened? “Why?” As a commercial pilot with almost forty years’ experience, and a captain with Ethiopian Airlines for nearly two years, however, I believe I know exactly what happened. And who was to blame. I want those responsible to be held to account. People ask me why I bothered to write this book. Did I think it would make a difference? What reasons could I have? No one would listen. “I have one hundred and fifty-seven very good reasons,” I say. And I still have hope that something will change, that someone will listen. And that maybe the crew and passengers killed on Flight 302 will not have lost their lives in vain.
