Ever since seeing these ‘Maunsell forts’, while on a fishing trip, I’ve been fascinated by them. They’ve put in an appearance in Cowl and now, sort of, in The Departure. They came up in a chat on Twitter about that book (about the stinking reviews on amazon). In the book they aren’t there but in their place is Maunsell Airport … in fact Boris Island Airport. Thanks to David Hutchinson for the link to this video clip.
