Ha, fair enough!
I found the continuation of the text I quoted in part:
associated with the Beaver.
"Design it so the wings don't come
off!" urged Frank MacDougall, a pilot
and deputy minister of the Ontario De-
partment of Lands and Forests.
MacDougall was looking for a reliable
airplane to replace his department's fleet
of flimsy Stinson SR-9s, one of which
had lost its wings in flight. De Havilland
complied; strut-braced wings (the initial,
tentative concept had included cantile-
ver wings), steel from the engine to the
fire wall, a heavy aluminum truss frame
in the cockpit area and a reinforced
cabin floor instilled enough beef in the
Beaver and confidence in MacDougall
for an order of 16 airplanes.
I have little knowledge of the Stinson SR-9 mentioned, other than to say, that as a teenaged camper back in the early '70's, I was flown into summer camp once in one (all the other times Cessna 185's). That one Stinson suffered a fatal crash very close to where we were canoe tripping one summer. Beaver's are tough!
