A US congressional report found that Boeing hid design flaws in its 737 Max jet from both pilots and regulators so that it could get the aeroplane certified as soon as possible.
The 737 Max was grounded last year following two of these aircraft crashing within months of each other, which resulted in the deaths of 346 people.
Investigators found that both crashes were caused by a faulty sensor which activated the plane’s anti-stall system by mistake. This dipped the planes’ noses downwards.
