The Mount Cook 748 leased by Dan Air was G-AYYG. it operated for them during the following periods, returning to New Zealand at the end of each lease:
17/06/78-18/10/78; 02/04/79-17/09/79; 09/04/80-22/10/81
During the leases it retained its Mount Cook blue colours with matching blue titles and the floral tail emblem was retained.
The aircraft itself was interesting. It was built as a demonstration aircraft and first flew in Hawker Siddeley house colours. In 1973 Howard Hughes entered into a lease purchase arrangement for the aircraft and travelled to Woodford to see it. He then decided he wanted to learn to fly the 748, but not his own aircraft. He arranged to charter a Rousseau Aviation 748 which he flew in and out of Stansted. He only saw YYG the one time, never flew in it and after his death it was sold to Mount Cook, having spent years in the Woodford flight shed.
After service with Mount Cook it went on to Canada then back to the UK where it was eventually retired in 2011
