Why was Sitka spruce considered a legendary material in early aviation history?
Answer
It possessed remarkable elasticity and strength for absorbing flight loads
Sitka spruce became essential because of its mechanical properties. Its ability to bend and flex under tension without snapping made it perfect for airframes that needed to endure the physical demands of takeoff, landing, and maneuvering. Unlike more brittle materials, it could handle the stresses imposed on the structure during flight, ensuring the integrity of the aircraft frame.
