Details began to appear regarding the last moments of a flight of Ethiopian Airlines, which crashed three weeks ago.
An anti-stall system in the aircraft, a Boeing 737 Max, is at the origin of the disaster that took the lives of 157 people on board.
Shortly after takeoff – and only 137 m (450 ft) from the ground – the plane began to pitch up.
According to the Wall Street Journal, one driver told the other "ride, ride!" before the death of their radio.
The plane crashed only six minutes after the start of his flight.
& # 39; Catastrophic failure & # 39;
The Wall Street Journal – who says he spoke to people close to the ongoing investigation – says the information he's "" paints a picture of a catastrophic failure that quickly swamped the company. " 39, flight crew ".
Leaks from the crash investigation in Ethiopia and the United States suggest this week that an automatic anti-stall system had been activated at the time of the disaster.
The flight control function of the Maneuvering Enhancement System (MCAS) was also involved in a fatal accident involving a Lion Air flight to Indonesia last October.
The Boeing 737 Max broke down shortly after taking off from Jakarta, killing 189 people on board.

An investigation into Lion Air's flight revealed a dysfunctional anti-stall system and forced the plane to nose down more than 20 times before it crashed into the sea.
The Ethiopian authorities have already indicated that there were "obvious similarities" between the Lion Air incident and the crash of Ethiopian Airlines.
The airline and the authorities declined to comment on the leaks resulting from the investigation.
The concerns raised by the Boeing 737 Max have resulted in the grounding of the aircraft around the world.
System update
Boeing has redesigned the software in order to disable MCAS if it receives conflicting data from its sensors.
As part of the upgrade, Boeing will install an additional warning system on all 737 Max aircraft, which was previously an optional security feature.
None of the two aircraft involved in the fatal crashes carried the warning system, designed to warn pilots when sensors produce conflicting readings.
The aircraft update is designed to ensure that the MCAS will not make more repetitive corrections when a pilot is trying to regain control.
Boeing is also in the process of revising the pilot training to improve "the understanding of the 737 MAX flight system" and crew procedures.

Earlier this week, Boeing said the upgrades were not an admission that the system caused the accidents.
The investigators have not yet determined the cause of the accidents, but a preliminary report from the Ethiopian authorities is expected in the coming days.
Boeing attempted to restore his battered reputation, while continuing to insist that the 737 Max was safe.
