The Letord (sometimes written as Letort) Let.7 was a military aircraft produced in France during the First World War, as a long-range reconnaissance aircraft, bomber and bomber escort. They were biplanes of unequal span with prominent and characteristic negative stagger on their wings. They were powered by twin engines mounted on short struts on the lower wing in tractor configuration, and had fixed tailskid undercarriage. Many of the subtypes were also equipped with a nosewheel to protect the aircraft and its crew from "nosing over" accidents while landing. The pilot sat in an open cockpit, with tail gunner in an open position amidships, and a third crewmember in an open position in the nose where he could act as gunner, observer, and bomb-aimer.
