Which specific types of wood were favored for the primary framing of early aircraft?

Answer

Spruce, ash, and basswood

These particular wood species were selected because they offered the best balance of structural strength and low density. Spruce, in particular, was highly valued for its superior strength-to-weight ratio, which was critical for managing the stresses of flight when every ounce of weight mattered. These woods allowed builders to construct complex trusses and spars that could withstand the operational forces of early aircraft.
