Boeing updated an existing plane, the 737 NG, because designing, building and securing approval for an entirely new plane could take as long as 10 years, and Boeing was pressed by a new plane from Airbus, the A320neo. But the larger, more fuel-efficient engines on the MAX forced designers to place them closer to the fuselage and farther forward on the wing. This changed the plane's handling characteristics.
Boeing said that management was unaware of the issue until the October 2018 crash in Indonesia, which killed 189 people. The planes were not grounded worldwide until after another 737 Max, operated by Ethiopian Airlines, crashed in March, leaving a further 157 people dead.
Boeing's stock closed Wednesday at 0.50 a share, up .50, or 1.04 percent. The 52-week range is 2.47 to 6.01 a share.
Both countries should be cautious in handling the issue, with a bigger picture of strategic and peaceful cooperation in mind.
