The training manual titled X-wing Flight Manual was authored by Barion Raner, known as Blue Four while serving with the Rebel Alliance's Blue Squadron. Within its pages, it detailed maneuvers like the Offensive Split and the Crossturn. The complete text was later disseminated on the HoloNet by Alliance Intelligence. Poe Dameron, a pilot within the Resistance, committed Raner's guidelines to memory during his childhood; these were later referenced by him in annotations within The Rebel Files.
