Zlatko Glusica was the captain of an Air India Express plane carrying 166 passengers from Dubai to Mangalore, a bustling port city on India's southern coast. As his Boeing 737 approached the city, Mr. Glusica woke up from a nap in the cockpit and took over the controls. His co-pilot warned him repeatedly that he was coming in at the wrong angle and that he should pull up and try again. The last sound on the cockpit recorder was the co-pilot screaming that they didn't have any runway left. The plane overshot the landing and burst into flames. Only eight people survived. An investigation found that the captain was suffering from "sleep inertia."
