Four Minutes From Landing

It's 1947. A plane is on its approach to Chile's Santiago airport and reports being four minutes from landing. Three times it sends a Morse code message no one can understand. The plane never arrives. No wreckage is found.
Seventy-two years later the plane mysteriously appears piece by piece far away from its destination. Charlie Fisher immediately connects it to the loss of her grandfather, the pilot of the plane. Determined to discover the truth, Charlie sets out on a personal quest that exposes her to both an Establishment cover-up and a ruthless thief, and which puts her life in danger.
