Boeing , which trust to have the 737 Max back in service by the heart of this yr , has look scandal after scandal take after two crash with the Max planer just five month aside . Ethiopian Airlines Flight 302 break apart in Ethiopia on March 10 , 2019 , killing all 157 passengers and crew on card , and Lion Air Flight 610 crashed in Indonesia on October 29 , 2018 , stamp out all 189 people on plank . The plane ’s unexampled Maneuvering Characteristics Augmentation System ( MCAS ) was reportedly pull the nose of the plane down erroneously because it conceive the planing machine was in danger of crashing .

The FAA and Boeing ground every 737 Max operating in the U.S. in March of 2019 , but only after almost every other commonwealth in the universe that was operate on the aircraft ground the plane on its own .

Boeingfired its CEOin December following the seemingly never - end series of scandals with the Max plane .

Despite yet another problem with the plane , Steve Dickson , the head of the Federal Aviation Administration ( FAA ) , seemed optimistic that the planing machine would return to service , concord toReuters , and has previously suggested it might be up in the sky before mid-2020 . The only question that stay is whether passenger will want to aviate on the doomed airplane . United and Southwest have already announce that they ’ll leave passengers the ability toopt - out of flying on the 737 Max .

Would you fly on the planer ? Employees at Boeing ask each other exactly that question before the two crashes in 2018 and 2019 .

“ Would you put your kinsperson on a Max simulator trained aircraft ? I would n’t , ” one Boeing employee write in an e-mail inFebruary of 2018 .
