A bus driver going over the Skye bridge could have located them,
Funny you should say that. A few weeks ago the police nearly asked HMS Astute to move along as she was causing a traffic jam. People were stopping and watching as a personnel change over took place.

Going outside navigation channels is not necessarily a bad thing. After all, if sea going naval vessels always stuck to navigation channels it would be rather easy to find them. This area is also often used for contractor crew changes.
