Return of Co van Tijen after his flight to the Netherlands East Indies in this light aircraft in late 1930. Actually, the plane had been shipped back to Holland and Van Tijen was picked up with it in Cologne by his flying instructor, Willem van Graft. A grand welcoming cermony had been organised by stakeholders including Pander, the NLS flying school, and Van Tijen's employer, Van Houten's chocolate factory which sent 200 girls to form the letters 'VH' on the platform.

Seating up to 20 passengers the F.IX was Fokker's largest trimotor airliner. There was little wrong with the design but its appearance coincided with the Great Depression and only two examples were built for KLM. The Avia company in Czechoslovakia built the type under licence as an airliner and bomber. Photo from: Haags Gemeentearchief

The Pander E was a sport and training sesquiplane first flown in 1926. PH-AFN was owned by Co van Tijen, export manager of Van Houten's chocolate factory. He flew solo to the Netherlands East Indies in this light aircraft, Adelaar (eagle) in 1930. He became general manager at Fokker in 1935. Photo from: Amsterdam City Archives
