On February 28th, 2018, an Airbus A320 encountered a cascade of critical failures while on a training exercise in Tallinn, Estonia. The flight controls had stopped working, the flaps were stuck, and the right hand engine had caught fire. The cockpit was filled with a terrifying array of bells and alarms, as the pilots tried desperately to bring the plane back for an emergency landing. How had this routine training exercise gone so terribly wrong, and how would the flight crew get out of this life and death situation? This is without a doubt, one of the most fascinating and unlikely stories in the history of aviation. This is the story of Smartlynx Estonia flight 9001.
