A Douglas A-1 Skyraider named "Peregrine," aircraft number 258, sits parked within a protective earthen and steel revetment at a Southeast Asian airbase during the Vietnam War. A crewman stands casually on the wing, illustrating the close working relationship between Skyraider pilots and their ground crews. Revetments like this one were built to shield aircraft from rocket and mortar attacks common at forward air bases. Project: 218942
