1 Emily: Do you chaps happen to know anyone in the German military?
2 Monty: Well, sort of... Why?
3 Emily: There’s a Luftwaffe Heinkel He 59 tailing us.
4 Prof. Jones: I see what’s going on here. You’re trying to distract us from the fact that we’re flying in a tiny plane with no food or entertainment.

The Heinkel He 59 was a German floating biplane designed in 1930 for torpedo bombing of ships and reconnaissance activities, and remained in service until 1944.

Germany had so many candidate aircraft models in this era, it was difficult for me to choose the most realistically appropriate, and I am fully prepared for a military aircraft enthusiast reader to tell me how wrong my choice was.
