Upgraded system shines light on nation’s ‘first’ airport

Boston's Logan International Airport has always been an airport of "firsts." In 1987, the airfield at Logan became the first to computerize airfield lighting. A recent upgrade to the lighting system again makes use of the latest computer technology, innovative software solutions, improved Programmable Logic Controllers (PLCs) and better communication bus systems.
