I'm trying to write a story in which the main protagonist is a fictional Polish spy, who has to retrieve a 'macguffin' that's been captured from the Germans. It is set in the spring of 1943. She therefore needs to get into German-occupied Poland, and back out afterwards (which is the main focus of the story), avoiding Wehrmacht and Gestapo patrols.
What kind of aircraft would be used for the drop, and where would it have flown from?
I'd originally envisioned a Lysander flying via Scandinavia, but then realised that there was no allied-controlled territory there at that time, so I'm assuming it would have been a parachute drop from a long-range aircraft directly from the UK?
