Communications have greatly improved. Today, by pressing a radio button, Anne Arundel County Fire units can communicate directly with Baltimore City as well as Howard and Baltimore county units. This modern technology didn't even exist in 1968. In addition, the National Incident Management System implemented following the September 11, 2001, terrorist attacks, has been practicing in the region for years. In the Baltimore region today, the city and counties run automatic mutual aid on first alarms, unheard of in 1968.
