Someone asked further back about Talair's Queenairs. I recall two, acquired in the Macair take over, which were based at Port Moresby, mostly for the Mendi scheduled air service. I believe both were finally operated by Solair. No idea where they ended their days.
The Unionair Queenairs often operated on mapping tasks in the PNG Highlands, probably in the early to mid 1970s. They were certainly operated at very high altitude.
Collin Codd also operated Queenairs.
There was an Excalibur Queenair based in Fiji and operated by Sunflower Airlines around 20 years ago.
I seem to recall an ex airline pilot owning or operating three Queenairs in the early 1990s, one of which had a "Dulux" major inspection in Manila before being sold off?
