Dar-es-Salaam Aero :
in this recording from 1986 you will hear Dar-es-Salaam and Kigali exchanging flight information (rb)
this letter is from the former operating agency IAL (Peter Conway, 1975)
very detailed QSL letter for the air/ground services (Michael Oexner, 1984)
another detailed one for the aeronautical fixed telecommunications network (rb, 1984)
QSLs like these give a feeling of a useful hobby to the DXer... (Michael Oexner, 1984)
