Publisher's blurb: One of our Darkisle reources, designed for use with a 1920s British Call of Cthulhu campaign in mind, but generic enough to be used in other settings or with other games set during that era. On a Wing and a Wave describes a small airline operating a single flying boat to a remote backwater. Full technical details are given for the Supermarine Sea Eagle, a real aircraft of the time, with two suggested liveries and a mono line diagram to use if you want to design your own.
