Crash investigators released the first image of the black box of Ethiopian Airlines Flight ET302. The photo of the mutilated flight data recorder of the Boeing 737 Max 8 aircraft was released Thursday by the French government.

Flight ET302's Black Boxes, a colloquial term used to describe the Cockpit Voice Recorder (CVR) and the Flight Data Recorder (FDR) of an airplane, were restored on Monday.

The recorders could provide the investigators with important clues that could uncover the cause of the crash and ultimately solve the puzzle, which is not true with the Boeing 737 Max.

With the US National Transportation Safety Board helping Renton's Renton aircraft built in Washington, it was assumed that the black box would be sent to the US.

Instead, the Ethiopian authorities handed over the writers of the BEA, the prestigious French aviation authorities.

According to the National Transportation Safety Board, FDRs for modern aircraft are required by law to record at least eight key parameters, including time, altitude, airspeed, and aircraft attitude. However, advanced recorders can monitor more than 1,000 parameters.

Older devices used magnetic tapes for data recording. Modern FDRs, however, use digital technology that can record up to 25 hours.

This is exactly what the voice recorder does in the cockpit. It records what's going on in the cockpit, including radio transmissions, background noise, alarms, pilot sounds and engine noise for up to two hours.

Both recorders are stored in reinforced enclosures that survive 30 minutes at 1000 degrees Celsius heat and are immersed in 6,000 feet of water.

On Sunday, Ethiopian Airlines flight ET302 crashed shortly after take-off from Addis Ababa Bole International Airport. The incident in which all 157 passengers and crew members were killed on board was the second almost brand new Boeing 737 Max 8, which had crashed in four months. Lion Air Flight JT610 crashed in Jakarta, Indonesia on the 28th of October.

Regulators and airlines in more than 50 countries around the world, including the US, have grounded the passenger planes. The Boeing 737 Max was put into service in 2017. Currently, 371 of the jets are in operation.
