köken: 16th century, from ge- (collective prefix) + Schwader. The latter is from Middle High German swader, from Italian squadra. The sense “group of birds” (16th century and thus predating aviation) is derived from the cavalry use.
köken: From French escadre, Polish eskadra, Russian эска́дра (eskádra), German Eskader. Compare Spanish escuadra, Italian squadra. Doublet of eskadrono.
