A United Airways Holdings Inc. plane ran off the taxiway right into a grassy space after touchdown at Houston on Friday, marking the third headline-grabbing incident this week involving the provider’s Boeing Co. planes. United Flight 2477, with 160 passengers and 6 crew, had simply landed at George Bush Intercontinental Airport about 8 a.m. native time when it veered into the grass on a flip. Nobody was injured, and passengers left the 737 Max on a set of cell stairs earlier than being bused to the terminal, the airline mentioned.
