In the first episode of a new series, presenter James Crawford explores how we have managed to surmount the challenges of our tough terrain to connect communities and places across the centuries. He takes to the air in a seaplane, landing in Loch Ness to reveal its geological secrets, uncovers traces of our Viking past, explores how we have crossed the treacherous Pentland Firth and flies above the stunning West Highland line. Finally, he visits the Highland crofters, going where no crofter has gone before at Scotland's first spaceport.
