The patent is for use with an aircraft to provide window capability i.e., visibility for scanning and for looking out over wide angular regions while the aircraft is in a flight mode. The inventive window includes a rotatable band positioned to form the external surface of the fuselage immediately aft of the aerodynamically configurated nose section, and with the band completely rotatable about the roll axis of the aircraft and, a window envelope which includes a transparent windowpane that is flush-mounted in an opening in the rotatable band, that is hingedly connected at its fore end edge to the opening, and that can be moved outwardly into the airstream at its aft end edge.
