Hamish on route - Norwegian plane, or is it a rocket?

First stages of the map page showing Hamish and Scottie on their way over from Edinburgh to Oslo - a few things to add, such as the islands, the rigs, the whales and maybe, Nessie taking a wee trip into the North Sea. Can't decide whether the background should be dark as at night maybe with a few stars or a bright blue sky ... that Scottie has his feet up on the seat and will get into trouble with the Captain if he finds out.
