N15-709 was delivered in 1973 for electronics countermeasures training. Decommissioned in 2000, it was ferried out of Australia as 3C-QQP in May 2001. It reached Norwich, UK only to be sold back in Australia to Horizon Airlines. 3C-QQP arrived at Sydney's Bankstown airport in July and was due to be fitted with a large cargo door when Horizon ceases operations. It was last reported with the Bankstown Aviation Museum with dummy engines and props.
