Link and his company had struggled through the Depression years, but after gaining Air Corps interest the business expanded rapidly and during World War II, the AN-T-18 Basic Instrument Trainer, known to tens of thousands of fledgling pilots as the "Blue Box" (although it was painted in different colors in other countries), was standard equipment at every air training school in the United States and Allied nations. During the war years, Link produced over 10,000 Blue Boxes, turning one out every 45 minutes.<ref name="Link"/><ref name="Sky to Sea">{{cite book|last1=Van Hoek|first1=Susan|last2=Link|first2=Marion Clayton|title=From Sky to Sea, A Story of Edwin Link|date=1993|publisher=Best Publishing Co.|location=Flagstaff, AZ|isbn=0941332276|edition=2nd}}</ref>
