To my knowledge, wood, being a natural composite, is, actually, less affected by fatigue, then crystalline material such as metal.
This is not my quotation, its I was find in mechanics related forum where experts explaining how it work based on Mechanics of materials :
1. The tree along fibers behaves as a fragile material, across - as plastic
PS metal material is plastic in both directions.

2. Stability - loss the most artful kind of destruction. It occurs suddenly. The most simple example-ruler(wood) which it is compressed length ways. It resists to the last, then suddenly curved and breaks.
PS Metal ruler doesn't braking in this way.

I'd really like to see a Wöhler diagram for both wooden composite and aluminum spar of equal terminal strength...
I agree. The present time wood material (really its a composite) can be equal of metal or better like metal, but I was talking about materials what was used at WW II. Thats not identical like used at present time. The plane is a very complicated mechanics device and flaying is a very stressfully action. So many forces with different strength was work on plane in flight. And if our plane caring bombs and drop its in diving, stress forces increased.
