Thanks giepasserin for the references and correction of the registration!
Please remove BHB registration if you have it installed, this update fixes the callsign.
A extremely difficult airline to research, Viacao Aerea Bahiana started with technical support from the all-powerfull Panair (and thus the base livery) in 1945 but after one of its Lodestar 18 crashed in 1948 it folded.
It was also the sole brazilian operator of the Boeing 247, which was purchased from and then sold back to Avianca.
