Trainer of Flieger-Ausbildungs-Regiment 12, making a flight from Hagenow to Münster, strayed into Dutch airspace and crashed in the city of Hengelo. Accompanying Gotha Go 145 WL-IKOL landed at Twenthe airfield. The wing shape confirms this as an Ar 66. Interestingly, although many Dutch people believed they would stay outside any war, a left-wing local newspaper wrote that the 22-year-old pilot acted as if he had conquered Holland on his own, telling people not to take photos of the wreck.
