– [In 1977, the government of Mozambique moved to establish a single domestic airline operation by combining all of the private local and general aviation companies in the country called COMAG. Taken over are CASS (Companhia Aerea do Sul do Save), ETAPA (Empreza de Transportes Aereos de Pemba), EMAC (Empreza Mocambicana de Aviacao Comercio), OTA (Organizacoes de Transportes Aereos), SAB (Servicios Aereos de Beira), SAM (Servicio Aereo do Mocambique), SAN (Servicio Aereo do Norte), TAM (Transportes Aereos de Mocambique), TAC (Transportes Aereos Comerciais), TAN (Transportes Aereos de Niassa), TAT (Transportes Aereos de Tete), and TAZ (Transports Aereos de Zambezia). Medical evacuation, survey and agricultural flights were made, along with charters. The principal business, however, is scheduled services to 24 cities, towns, villages and airstrips. In 1980, the carrier was reformed and renamed TTA (Empresa Nacional de Transporte e Trabalho Aereo)]
