And with this question in my head I planned a flight from Cascais, LPCS, to Whitman Regional, KOSH, but flying in the virtual skies on Fight Simulator.
The aircraft for the journey was the Beechcraft Bonanza F33A from Carenado, a well advanced single engine with a quite good performance.
The route that I've choose was a northern one flying from Portugal to Spain then France and UK and then proceeding to Iceland and Greenland passing that entering Canada and proceeding southwest to KOSH.
Here are some Pictures of this trip. A very good one to who knows one day fly it in real sky.
