suggest an anti-stall system on the Boeing 737 Max has been highlighted as the cause of the crash.

Two minutes into the flight – at just 450ft (137m) above the ground – the aircraft's nose started to pitch down, according to The Wall Street Journal.

The newspaper, which says it's spoken to people close to the ongoing crash investigation, says the captain is considered to control the plane when it started to dive.

The detailed report says one pilot said to the other "Pitch up, pitch up!" Before the radio went dead and the plane "accelerated" towards the ground.

It crashed only six minutes into the flight.

"Catastrophic failure"

The Wall Street Journal says the information it has "paints a picture of the crash investigation in Ethiopia and in the US suggest an automatic anti-stall system was activated at the time of the disaster.

An investigation of the Lion Air flight suggested the anti-stall system malfunctioned, and forced the plane's nose down more than 20 times before it crashed into the sea.

The Ethiopian authorities have already said there are "clear similarities"

Concerns about the Boeing 737 Max have suffered from worldwide grounding of the plane.

System update

Boeing has redesigned the software so it will 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 safety feature

Neither of the two planes that were involved in the fatal crashes carried out by the alert systems, which are designed to be pilot when sensors produce contradictory readings. ] The aircraft update is designed to ensure the MCAS will be longer repeatedly make corrections when a pilot tries to regain control.

Boeing is also a revision of pilot training to provide "enhanced understanding of the 737 MAX" flight system and crew procedures. 19659018] Image copyright
