On Nov. 5, geologists noted changed emissions and minor melting near the Redoubt summit and raised the threat level from green to yellow. It jumped to orange - the stage just before eruption - on Sunday in response to a sharp increase in earthquake activity below the volcano. …

As the crew tried to restart the engines, “smoke” and a strong odor of sulfur filled the cockpit and cabin, according to a USGS account.
