Could RAF bombers actually navigate from Norway to Ploiești in 1940-42?
Short answerIt would be difficult, but the RAF could attempt it and improve its navigation through the effort.
NotesRAF navigation in 1940-42 would make a Norwegian strike on Ploiești difficult. The route is still within operational capability, and repeated attempts would force navigation techniques to improve. The answer does not guarantee accurate bombing or low losses. It preserves the oil threat as plausible while identifying navigation as a real constraint.
