The door was fully inspected and followed by a pressurization leak check. The crew who flew the same plane earlier that morning reported a frozen door seal and noises coming from the aft service door on the plane's right side. Therefore, those aboard the plane passed out due to a lack of oxygen in the cabin. The cabin was not pressurized before takeoff, likely due to issues the plane experienced earlier. Officially, this is what is believed to have happened. The official ruling? Lack of cabin pressure and oxygen rendered Flight 522 a ghost plane. Questions were left unanswered for some time, until a few key pieces of the plane were uncovered from the wreckage, including the cockpit voice recorder and a control panel. At first, they couldn't find the cockpit voice recorder. There were 121 fatalities, making this tragedy the deadliest in Greece's aviation history and the fourth deadliest crash of Boeing 737-300s.Īfter the crash, the investigation began to determine the cause. The crash of Flight 522 was the 69 th crash of a Boeing 737 since they were released in 1968. Not long after, the plane crashed in the hills of Grammatiko, 25 miles from Athens. No words were exchanged, but the person did see the jets. Then, the jet pilots spotted movement in the cockpit. No passengers seem to signify they saw the jets. They found that the captain was not in the cockpit and the co-pilot was slumped over in his seat and unresponsive. The plane continued to fly and two F-16s were sent to investigate. This was the last transition from Flight 522. Pilot: "Where are my equipment cooling circuit breakers?" Pilot: "The ventilation cooling fan lights are off."Įngineer: "Can you confirm that the pressurization panel is set to AUTO?" Unaware that the oxygen masks fell in the cabin, they radioed the Helios operations center and spoke with a ground engineer-the same one who had performed the pressurization leak check. They were unable to figure out why the takeoff configuration alarm went off and the equipment cooling warning lights went on. In the cockpit, the pilot, Hans-Jürgen Merten, and copilot became confused not long after takeoff. There were 115 passengers on board and a crew of 6. On a warm summer day in 2005, Flight 522 took off from Larnaca, Cyprus to Athens, Greece for a flight a little over one hour long. But what really happened? Helios Airways Flight 522 Takes Off Those on the ground thought it might be a possible hijacking. Imagine the absolute confusion and terror. You're up high, but the plane is still ascending. Imagine sitting comfortably in your seat during takeoff, everything seems to be going well, then the oxygen masks drop.
