If the wood you are buying or reading about is just called fir, it
probably is NOT Douglas Fir.

I think this depends upon where you are buying it. Here in Oregon 80% or so
(warning: unsubstantiated number) of the evergreens are Doug fir. I think
its pretty safe that the "fir" at my local lumber yard is indeed Doug fir.

Now, it is also second growth Doug fir and is hardly suitable for a dog
house much less an airplane.

They just don't make trees like they used to.
