What is "sabena"

The Societé Anonyme Belge d'Exploitation de la Navigation Aérienne, ( French; "Belgian Corporation for Air Navigation Services"), better known internationally by the acronym Sabena or SABENA, was the national airline of Belgium from 1923 to 2001, with its base at Brussels National Airport. After its bankruptcy in 2001, the newly formed SN Brussels Airlines took over part of Sabena's assets in February 2002, which became Brussels Airlines after a merger with Virgin Express in March 2007. The airline's corporate headquarters were located in the Sabena House on the grounds of Brussels Airport in Zaventem.
