- Letord Let.1
__NOTOC__
The Letord Let.1 was a military aircraft produced in France during the First World War, primarily as a long-range reconnaissance aircraft. Later versions, designated Let.2 through Let.7 were used in a variety of roles, including bomber and bomber escort. All were three-bay 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.Some 1,500 aircraft were ordered by the
Aéronautique Militaire between all the variants, with something like 300 actually produced before the end of the war.Variants
