@Mn-guy As your question is neither about the website nor the forum itself I have moved your topic to the A&A Classic Forum Category,
Is Eire and United Kingdom adjacent by land …
No.
… or you need a transport between the two?
Yes.
Can you go from Eastern Europe to Turkey? It works in the CD game, but I don’t remember anything in the rules about it being legal. That sliver of water between Istanbul and Europe is pretty insignificant, so I thought it might be possible.
No.
Only the Suez and Panama can be crossed w/o transports
that is a bug in the CD rom version that gets fixed in an update.
you also cannot have airplanes end their turn over the ocean as the computer sometimes does.
