Turnbuckles for Aircraft

This article discusses only turnbuckles used in aircraft. They are such small and inconspicuous parts of an airplane that their importance is usually overlooked, but no element in an airplane is more vital. In double wired machines the breakage of one turnbuckle may not have serious results, but in single wired machines one failure often means the loss of a plane and its occupants.

Types of military apparatus which are considered necessities today may be on the scrap heap tomorrow; and yet by a curious reversal of conditions the obsolete, the forgotten, often comes back to play again its part in a new generation. There have been many illustrations of this during the present war.
