This week, the Prime Minister's Air Force plane broke down in Papua New Guinea. 

Senior Political Correspondent Barry Soper breaks this down, as he wraps the political week. 

Soper told Heather du Plessis-Allan “They’re very good planes – but it’s like anything – if you don’t use them, they’ll break down.” 

Soper said “They’re only used as VIP aircraft about 15% of the time.”
