THIS IS A GHOST STORY. FOR THE PAST 46 YEARS, the two of us—Ken, a newspaper publisher, and me, a history professor—have been haunted by what happened to Pan American Airways Flight 7 early in the evening of November 9, 1957. The airliner, Clipper Romance of the Skies, was on the first leg of a round-the-world journey that began earlier that day in San Francisco. Its next stop was to have been Honolulu, but the Boeing 377—known by the airline as PAA-944—never arrived. It crashed in the Pacific, killing 44 people, including Ken’s father, second officer and navigator Bill Fortenberry, and flight attendant Marie McGrath, who had been my fourth grade teacher.
