Investigators say a 42-year-old flight instructor in Argentina jumps from a Cessna 150 during a lesson, leaving a 22-year-old student to land the aircraft by herself. Multiple outlets report that Leandro Andrés Bertazzo removed his headset and seatbelt, opened the door, and leapt out mid-flight. Witnesses and reports quote him telling the student, “you know what you have to do,” before he left the plane. The student subsequently lands the aircraft safely, according to reports citing authorities and aviation training sources. A flight school director and others express shock at the incident and say there were no obvious prior warning signs. Authorities are investigating the circumstances leading up to Bertazzo’s actions and whether any medical or personal factors played a role. One outlet reports that Bertazzo had been seeing a psychiatrist, but it also says colleagues were not told. Details of the investigation, including motives and contributing factors, are ongoing.
