Italians also created new airports and in 1936 started the worldwide famous "Linea dell'Impero", a flight connecting Addis Ababa to Rome. The line was opened after the Italian conquest of Ethiopia and was followed by the first air links with the Italian colonies in Italian East Africa, which began in a pioneering way since 1934. The route was enlarged to 6,379 km and initially joined Rome with Addis Ababa via Syracuse, Benghazi, Cairo, Wadi Halfa, Khartoum, Kassala, Asmara, Dire Dawa. There was a change of aircraft in Benghazi (or sometimes in Tripoli). The route was carried out in three and a half days of daytime flight and the frequency was four flights per week in both directions. Later from Addis Ababa there were three flights a week that continued to Mogadishu, capital of Italian Somalia.
