The top U.S. aviation regulator ordered the temporary grounding of certain Boeing 737 MAX 9 aircraft for safety checks following a cabin panel blowout late Friday that forced a brand-new airplane operated by Alaska Airlines to make an emergency landing. A piece of fuselage tore off the left side of the jet operated by Alaska Airlines as it climbed following takeoff from Portland, Oregon, en route to Ontario, California, forcing pilots to turn back and land safely with all 171 passengers and six crew on board. The plane had been in service for just eight weeks.
