"Federal officials later confirmed that an airfield warning system had not activated because of a software error that prevents the system from detecting planes approaching each other on intersecting runways."
Yeah, that would be a good feature to have.
I find it unsettling that the Massport CEO wants FAA action against pilots involved in incursions. We need better preventive measures, not more punitive measures. Plus, more incursions may go unreported if the FAA promises swift justice.
