A typical morning -

Andreas Lubitz -

The 27-year-old co-pilot, Andreas Lubitz, should have had no problem keeping the flight on track during the pilot's short absence.

Route -

However, something happened in the cockpit when Lubitz was left alone. Flight records indicate that as soon as the pilot left, Lubitz adjusted the plane's altitude and began to slowly descend the aircraft.

Control tower -

Within a few minutes, air traffic controllers noticed the loss of altitude and made unsuccessful attempts to contact the cockpit. They continued trying to talk to Lubitz while noticing that he was increasing the plane's speed. He didn't respond.

The pilot comes back -

At this point, the pilot returned from the bathroom and rang the bell to the cockpit, which is always locked for security reasons. However, Lubitz did not answer him or unlock the door.

Crime inquiry -

Soon after, it was reported that Andreas Lubitz might have intentionally crashed the plane, which stunned the world.

Andreas Lubitz -

It was discovered that Lubitz had a history of severe depression. A few years earlier he had taken a break from his pilot training to undergo treatment for his mental health. It was reported that he had suffered from a serious depressive episode and considered taking his own life. After working with a psychiatrist for several months and taking antidepressant medication, he was cleared to return to training.

Andreas Lubitz -

Investigators discovered a doctor's note in Lubitz's trash during the home search. The note stated that he was not fit for work and excused him on the day of the crash. This finding indicated that Lubitz was aware of his issues but still chose to report for duty. The investigation confirmed that he had premeditated the plane crash. The records from his previous flights indicated that he had purposely practiced lowering the plane's altitude multiple times when he was alone in the cockpit.

Wreckage -

Upon the investigation of the wreckage, experts concluded it had been a strong collision. It's believed the aircraft struck the mountain at a speed of 700 km/h (430 mph), causing instant death to all those on board.

Explanation -

As more information came to light, the theory that the crash was caused by the co-pilot gained credibility.

Intentional acts -

One damning fact was that the plane's altitude was suddenly changed from 38,000 ft to 100 ft while Lubitz was alone in the cockpit. Experts confirmed that this change could only be done manually and deliberately.

Controlled landing -

In addition, the descent was carefully controlled, which ruled out the possibility that the crash was caused by Lubitz's lack of ability.

International aid -

The tragedy prompted global media and leaders to quickly express their solidarity with the families and friends of the victims.

Revised regulations -

Following the 9/11 terrorist attacks, cockpits were fortified to ensure maximum security. However, after the Germanwings tragedy, concerns over potential threats from inside the cockpit arose. In response, several airlines implemented regulations prohibiting pilots from being unaccompanied in the cockpit. These measures were introduced in the aftermath of the accident.

Legal proceedings -

Lufthansa, the company that owns Germanwings, the budget airline, chose to give €75,000 (US$85,000) to each of the families of the victims, and €10,000 (US$11,300) to close relatives.

Legal proceedings -

Some families tried to sue Lufthansa and the flight school attended by Lubitz, but it was concluded that they were not at fault for the accident.

Memorials and tributes -

In 2017, an artist from Germany placed a significant sculpture at the location of the accident known as Sonnenkugel, or "Sunsphere." The artwork consists of 149 adorned panels, representing each individual who tragically lost their life in the crash. However, one panel was deliberately excluded for Lubitz, the 150th passenger aboard the aircraft.
