How can an aircraft literally vanish in thin air? It started as a calm and clear night in Kuala Lumpur when 239 passengers and crew members boarded a routine flight to Beijing, China. With a highly experienced crew and a well-maintained Boeing 777, flight 3501 took off on time with passengers settled in for the overnight trip. But what first appeared to be a routine flight, suddenly became a situation that mystified not only the airline industry but also captured the attention of governments around the globe. Not long after takeoff, the transponder was turned off for no apparent reason. The plane veered off course, taking wild dips and turns before heading into the open Indian Ocean. But did it really crash? The transponder was turned off, making it impossible to track the plane's movements. There was no communication with air traffic controllers. No part of the plane was ever found. No bodies were ever discovered. Airplanes don't just disappear into thin air. Despite having no evidence, why did the Malaysian government quickly close the case? Did officials have knowledge not to be shared? Was there something or someone on this flight that would be worth the lives of 239 people? To uncover the truth on behalf of the family members, renowned aviation disaster investigator Sam Casey is hired to investigate. Casey finds himself in an unprecedented aviation mystery that extends beyond one missing plane. Navigating many twists and turns, Casey crosses the precarious terrain of world politics and what might be worth hiding, leaving the threat of a global imbalance of power.
