A small budget aircraft carrier from Germany's Lufthansa crashed into the French Alps on Tuesday, March 24, and sadly, all 150 passengers on-board were killed.

Rescue crew members made their way towards the crash site, despite the difficult terrain. "Horrendous images in this mountain scenery. Nothing is left but debris and bodies. Flying over the crash site with the interior minister - a horror - the plane is totally destroyed," said Local MP Christophe Castaner via Twitter. He had flown over the crash site as one of the many helicopters being sent in to assess the damage.

According to The New York Times, authorities and executives of the airline said they received no distress signal. Therefore, the cause of the crash remains a mystery.

At the crash site, officials were able to recover one of the two black boxes. A black box is a voice recorder located in the cockpit that records "up to two hours of the pilots' conversations as well as only other cockpit noises, including any alarms that would have sounded as the plane descended."

The plane had made an eight-minute descent from 38,000 feet before crashing into the French Alps. The French air traffic controllers had lost contact with the plane at about 11 am Tuesday morning as it was flying at 6,000 feet.

Francois Hollande, French President, said "It is a tragedy, a new airline tragedy. We will determine what caused the crash."

Germanwings said that roughly 67 Germans, 45 Spanish, some Turks and a handful of other passengers were aboard the plane along with six crew members. The chief executive of Lufthansa Carsten Spohr described it as a "dark day."

The investigation will continue until the cause of the crash is determined.
