Boeing's 737 Max on Wednesday was cleared by the Federal Aviation Administration to fly again. The jetliners were grounded for 20 months due to a pair of crashes in 2018 and 2019 that killed 346 people. The company got clearance for the plane to return to American skies after convincing the FAA that changes in design, software and crew training would eliminate the flaws that caused the fatal crashes. The FAA will let Boeing resume delivery of newly produced 737 Max aircraft, which will have the design changes in place. The agency itself will issue the Airworthiness Certificate for each aircraft. Boeing used to do that. (Sources: multiple, including CBSNews, New York Times, 11/18/20) Gulf Coast note: The 737 competes with the Airbus A320 passenger jets, some of which are built in Mobile, Ala.
