Contrails
From USAFA Folklore
Contrails is a pocket-size book that contains the knowledge all fourth class cadets are expected to learn during their first year, including quotations, aircraft, Air Force history and information about the operational Air Force and the Academy. Contrails has been prepared by a cadet staff since 1956. The cover of Contrails is typically the class color of the class it was issued to.
Originally, basic cadets received their Contrails on Inprocessing Day, but in more recent years, they have been issued a Contrails "extract" (sometimes referred to as "Wingtips") for BCT and been issued their full Contrails at Acceptance. Starting in (when?), the Association of Graduates has coordinated a formal presentation of Contrails to fourth class cadets by members of their "Legacy Class"--the class that graduated 40 years prior to the year the fourth class will graduate.
