A Beech B200 Super King Air reportedly activated its Garmin Emergency Autoland feature during a flight from Aspen to Denver. Initial reports suggested the two pilots were incapacitated, leading to the automatic landing. However, Flightradar24 indicated the pilots remained alert and operational, triggering the system due to a complex situation including loss of pressurization, challenging weather, and terrain. The pilots monitored the autoland system's performance during the safe landing.
