As I mentioned before, the three people standing alongside the plane are, from left to right, John Shark (not Sherk like I wrote before), Mrs. Mable McIntyre and Jack Andison.
The only one of these people I knew was Andison, who was a great person and a very interesting gentleman.
I believe all these people have passed away, but are not forgotten. This photograph was taken at Mayo airport in 1930.
Thank you to Bob Cameron for this reply:
The aircraft in your Colourful Five Per Cent Scrapbook of March 10 is the Mayo-based De Havilland Cirrus Moth of Klondike Airways.
Its registration letters were G-CAUM, and it was christened Rilla Martha; after whom, I do not know. This aircraft has been featured in previous CFP photos.
Klondike Airways, owned by T.C. Richards and W.L. Phelps, was in the business of hauling freight and mail to Dawson and Mayo by cat train.
It is not clear why they purchased this aircraft, as they had neither the expertise nor the intention of operating it themselves.
Instead, they turned it over to the Treadwell Yukon Mining Company, which was operating a Fairchild aircraft, and which used the Moth merely for training and joy riding.
As to the folks in the photo, I, like many others, remember Mable McIntyre (and her unforgettable laugh!) when she was the postmistress in Mayo. I went to school with a guy named Bob Andison from Mayo, whom, I suspect, would have been a son or grandson of Jack.
