The onscreen map for the seventeen-hour flight is quite eccentric, showing initially only Brize Norton, Washington and Ankara, before giving up on names altogether, once over the Atlantic. For several hours the screen resembles an Yves Klein canvas, before a tiny dot appears in the top right-hand corner, followed, minutes later, by one of the more surreal in-flight announcements: ‘We will soon be starting our descent into Ascension.’
