A JetBlue flight transporting passengers to San Diego diverted from its planned route and made an emergency landing at a regional airport in central Kansas Saturday evening.

The Jet2 passenger plane made an emergency landing in Cologne, and he was led off the plane to the awaiting emergency services. As he walked down the steps from the plane to the runway, the 40-year-old collapsed, and died a short time later.

A JetBlue flight from New York City to San Diego landed safely in Kansas after the crew received an alert about smoke in the cargo area, authorities said. The airline said it turned out to be a false alarm.
