@amazeifystore: Why did Helios 522 keep flying with no one at the controls? ✈️ After maintenance, the pressurization selector was left in manual mode. As cabin pressure fell, the crew misread the warning, and hypoxia incapacitated the pilots. The autopilot kept the aircraft airborne until it ran out of fuel. A sobering reminder to verify cabin altitude and selector mode. What safety checks do you think matter most? #Helios522 #AviationSafety #AviationHistory #FlightSafety #Hypoxia #AircraftMaintenance #AirDisasters
