As promoted since the beginning, Drubware adds another language to FS Cabin Crew. The flight attendant, pilot and copilot voices can be heared now in Spanish.
If you already have a complete English or German Edition, then just purchase FS Cabin Crew Spanish Pack. If you just want the Spanish voices, i advise you to get FS Cabin Crew Spanish Edition, and you remain free to purchase separate voice packs later.
