They have baffled experts. From Amelia Earhart’s Lockheed Electra to the MH 370 Boeing 777, at least 100 planes, and the people in them, have disappeared from the skies since humans first took to the air. For some, the cause has never been properly explained. For others, accidents and terrorism are responsible. A person has a one in 5,000 chance of perishing in a car crash compared to a one in 11 million chance of being involved in a fatal plane crash. But the mystery and speculation surrounding a vanishing plane generate great drama. And it’s not just planes, but also ships that seem to disappear off the face of the earth. Chris McLeod’s Unsolved: Terror, Crimes, Accidents takes a fascinating look at many of these incidents.
