 During the late 1950s , Braathens SAFE started looking for a replacement for the aging DC @-@ 3s and Herons . An order was placed with Fokker for the delivery of their new Fokker F @-@ 27 Friendship , a two @-@ engine turboprop with cabin <unk> . Braathens SAFE was the second airline to receive the plane , after <unk> <unk> . The first craft , LN @-@ <unk> , was delivered in December 1958 , with the second , LN @-@ SUO , delivered the following year . They were put into service on the main routes : once daily Oslo – Trondheim , once daily Oslo – Ålesund , twice daily Oslo – Stavanger , including one stopping at Kristiansand , and one trip daily Bergen – Ålesund – Trondheim . The delivery of the <unk> made the Herons unnecessary , and these were sold . The two DC @-@ 3s were kept as a reserve , and were used for the first part of the summer schedules because of late delivery of LN @-@ SUO . They were also used for charter . The airports at Hamar , Farsund and Tønsberg had too short runways for the Friendship , and these destinations were terminated .
