I was an aircraft refueller at Newman, WA, in 1976-77. I remember VH-TNN well because I refuelled it many times. It was mainly white with a blue tailplane and some other light blue detail. I recall it flew to Forrest, also in WA, on a daily basis in relation to the mapping and aerial work being carried out. The crew were a great bunch of guys and this aircraft does get a small mention in a book I am currently writing.

As VH-TNN this aircraft flew much mapping photography for the Australian Division of National Mapping using a Wild RC-10 camera. This was contract work the then owner being Stilwell Aviation based at YMEN.

The majority was flown at either 25.000' or 41,000' while a smaller number of missions were flown at 45,000'.

A great machine, fondly remembered.
