Maintain standard of service
It was 1939 and the world was in turmoil. War was declared and flying became an unpredictable business for KLM: routes were closed and reopened, flights were re-routed and airports were shut down.
After guns had opened fire on a number of KLM aircraft, the airline thought it wise to change their exterior: the aircraft were spray-painted orange from nose to tail and the word 'Holland' was painted on the fuselage in large letters.
In spite of the constantly changing circumstances, KLM made every attempt to maintain its standard of service and reliability on the few remaining flights.
A Poster was even designed inviting day-trippers to visit Schiphol by train.
