NAB – Navegação Aérea Brasileira
NAB – Navegação Aérea Brasileira was a Brazilian airline founded in 1938. In 1961 it was sold to Lóide Aéreo Nacional. History. NAB was founded on January 28, 1938. The founder Paulo Venâncio da Rocha Vianna initially invested heavily in technical training for both land and air staff conducted particularly by TWA. Thus in the beginning NAB followed what was most modern in terms of aviation technology and administration at its time. Its first aircraft arrived in 1941 and operated between Rio de Janeiro and Recife via Belo Horizonte, Bom Jesus da Lapa and Petrolina. In order  to operate the route NAB invested in upgrading the airport facilities of Bom Jesus da Lapa and Petrolina. Later NAB tried also to fly between Rio de Janeiro and Recife via the coast but it had no success due to the fierce competition with Serviços Aéreos Condor (later Cruzeiro do Sul) and Panair do Brasil. Because of financial difficulties, the Brazilian government granted three successive subventions, which were used to enlarge the fleet and extend the network. The end of World War II brought a boom in the creation of new airlines in Brazil and due to fierce competition, in  order to survive, NAB was granted further two loans. In March 1948 all services were suspended and NAB was closed on August 17, 1948. This was however not the end: the Federal Government decided to take over NAB and continue services in the states of Rio de Janeiro, Minas Gerais and Espírito Santo. Thus the airline continued its struggle for survival. In 1957 the entrepreneur Dilvo Peres decided to invest in the airline, re-organizing its administration, buying new aircraft, and establishing an operational partnership with Panair do Brasil. The efforts were not successful and in a last attempt to  survive, NAB started selling greatly discounted tickets and in-flight service was reduced to a minimum. On October 24, 1961 Lóide Aéreo Nacional bought NAB. Destinations. NAB served, among others, the following cities:
