Runway excursions are the most common kind of airplane accident. This is the kind of incident that is only international news now because boeing is under scrutiny. Had this happened a few years ago this incident would be easily ignorable, only be reported locally or in aviation related news publications.
The aircraft involved was a 737-300, a model two generations before the max, on a production run that started in 1981, 14 years before the merger with mcdonald douglas. This incident is unlikely to be related to the current issues at boeing.
