No one died in the blowout that left passengers staring at open space 16,000 feet above the ground and forced the pilots to make an emergency landing. But the incident has turned into a full-blown safety and reputational crisis for Boeing that will slow plane production and risks it ceding further market share to Airbus. The withdrawal, first reported by Reuters, throws the anticipated timeline for certifying Boeing's Max 7 and the larger, better-selling Max 10 into further doubt because it may force Boeing to make design changes more quickly than it had planned. CEO David Calhoun withdrew the exemption request after being asked to do so in Capitol Hill meetings last week as Boeing grapples with growing safety concerns following the mid-air incident on a 737 Max 9 jet operated by Alaska Airlines.
