A flight instructor in an Argentinian city died last month. He leapt from a moving plane and hit the ground below. The instructor was killed from the fall. His student, aged 22, stayed in the cockpit alone. The student then flew the plane without incident to a nearby airbase. Rescue teams later searched the site. No person on the ground was hurt. Police are investigating the cause of the jump. Flight schools are re-examining safety lessons following the incident.
