Mark has been a pilot for more than 3 decades, starting with TWA. He’s still flying, now for American Airlines, and is also an author of several fiction and nonfiction books. We spoke about his early career flying 19-passenger Twin Otters in the Caribbean, to his wild checkride flying into Berlin during the Cold War. We also discussed his experience following the crash of TWA Flight 800 — his fiancée and one of his mentors were both on board — and his struggle with grief afterward, which eventually led him to write “13,760 Feet: My Personal Hole in the Sky.”
