As a furious squall swept down Lake Michigan on June 23, 1950, a DC-4 with 58 souls on board flew from New York toward Minnesota. Minutes after midnight Captain Robert Lind requested a lower altitude as he began crossing the lake, but Air Traffic Control could not comply. That was the last communication with Northwest Airlines Flight 2501. Shredded human remains washing up on the beaches of West Michigan served as evidence of the country's worst commercial aviation disaster. The Navy and Coast Guard never located the wreck, rendering it impossible to determine a cause for this tragic accident. Over a half century later, nationally acclaimed author and explorer Clive Cussler of the National Underwater Marine Agency teamed up with the Michigan Shipwreck Research Association to pick up the search where the government left off and attempt to solve the mystery of the plane's disappearance. This gripping and suspenseful narrative begins as the team sets out upon its quest, an expedition fraught with disappointments and surprising discoveries as the explorers plow through archives and scour the lake bottom. An unexpected meeting with a victim's son prompts a search of a different kind, one that would be more illuminating than submerged sections of twisted aluminum. Weaving past and present together through meticulous research and heart-rending interviews, V. O. van Heest paints a captivating portrait of the victims, vividly recreates the last few hours of Flight 2501, and reveals that the answers are sometimes found in unexpected places.
