Mfg flaw likely as flight window rip away 6 minutes after takeoff

Alaska Airlines grounded all of its Boeing 737-9 MAX aircraft late Friday, hours after a window and piece of fuselage on one such plane blew out in midair and forced an emergency landing in Portland, Oregon. After Friday's blowout, the Federal Aviation Administration (FAA) on Saturday ordered US airlines to stop using some Boeing 737 Max 9 planes until they are inspected. The order will affect about 171 planes. Friday's incident occurred shortly after takeoff and the gaping hole caused the cabin to depressurize.
