The message that Fokker had obtained his pilot's license in Germany also found its way to Haarlem, where the board of the Vereeniging Koninginnedag came up with the idea to invite this fellow townsman to give flight demonstrations. Queen's Day was then held on August 31. He was on the program between the pony races and the cake walk.
Fokker had not set high standards. He had agreed to cooperate against an expense allowance.
The board of the association was very happy with Fokker's commitment and placed large advertisements a few days in advance in the local newspapers, in which the flying demonstration on the party grounds in Schoten, behind huis ter Spijt on the Kleverlaan, was announced with great fanfare. .
