Episode #1.7 - S1-E7
Factual error: Harry parachutes from a German Junkers 52, which the RAF did not fly. And if they did, the exit door on a Junkers 52 is on the left side, not the right which Harry parachutes from.

Factual error: After escaping from Danzig, Grzegorz and Konrad flee to Warsaw, then to the eastern, Soviet-occupied part of Poland. They then make their way on foot right across occupied Poland and Germany to join British forces at Dunkirk, a distance of over 1,000 miles. Not a likely journey on foot at any time, let alone across hostile territory in the middle of a war.
