During the WWII the Swedish airline ABA continued its international flights with planes painted in striking orange.Björn Bäcklund has built, rescribed, slightly modified, cut his own masks and used a lot of orange color on a Monogram DC-3:
The orange color and Swedish markings didn't keep the plane from being shot down in 1943.
