Alaska Airlines Boeing Probe: What We Know

It has been three days since Alaska Airlines Flight 1282 made an emergency touchdown after a bit of the plane ripped off midair, leaving a gap within the airplane at 16,000 ft up. 

At this level, the probe by the National Transportation Safety Board into the accident is zeroed in on the Alaska accident and never on a broader set of plane, reminiscent of separate variations of the 737 MAX or different planes. The focus may change as proof surfaces about what occurred.
