Boeing on Tuesday said customers canceled another 60 of the company’s beleaguered 737 Max planes in June. That tipped Boeing’s net cancellations to 323 planes in the first six months of the year. Boeing’s 737 Max has been grounded since March 2019 after two fatal crashes killed 346 people combined. The Federal Aviation Administration late last month started flight tests that would pave the way toward the planes’ recertification, but their review will take several more weeks. The coronavirus pandemic has handed Boeing an additional and broader challenge as demand for new planes dries up. source
