1935 German Air Rally. Team F1 were from the Reich Air Ministry, in other words, the air force, with seven Ar 66c aircraft. They did not well, ending up in 26th place. Photo from: Life

Yet another crash of a strayed Ar 66 in the Netherlands. The pilot, 'reservist soldier' W Hage, tried to ditch in the Twentekanaal but came down on the canal's south bank near the hamlet of Wiene. He came across as inexperienced. Photo from: Nederlands Instituut voor Militaire Historie

Another Ar 66 crash on Dutch territory. The military pilot lost his way en route from Salzwedel to Wilhelmshafen and landed in the province of Groningen. He tried to take off again but hit a car and a cyclist who was killed. The pilot was court-martialled in Germany. The farmhouse stands little changed today. Its street address is in Spijk, but most sources give the hamlet of Zijldijk as the accident location. Photo by: W Hijlkema / Groninger Archieven

This 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.
