The airfield near Knokke - Heist was built in 1929 and airshows were held here for the benefit of the Red Cross. The Pander P-1, PH-AGM, and P-2 were two nearly identical Dutch parasol monoplanes built also in 1929. PH-AIK is another Pander, the P-3, and ZS-ACZ a DH.60G Gipsy Moth that became OO-ANG. The latter two planes date the photo in 1932. Photo from: KB - National Library of the Netherlands
