In the foreground, the G-2 has just been moored on one of the jetties of Vliegkamp De Mok on Texel.
And in the background the G-1, perhaps, just landed.
In the fall of 1939, this G-1, with a few other MLD aircraft, managed to force a German Dornier Do-18 flying boat to land.
This takes place on the Wadden Sea and the flying boat was flying to England.
Germany is already at war with the United Kingdom, but the Netherlands is neutral at that time.
Eventually, the Dornier is forced to return to Germany.
The fact that German planes deliberately violate the territorial borders at sea is a well-known behavior at the time.
