The Slingsby Hengist was a British military glider designed and built by Slingsby Sailplanes Ltd. Like other British troop carrying gliders in the Second World War, it was named after military figures whose name began with H, in this case the Jute invader Hengist.

[3] A total of 14 production Hengist Mk I were delivered to the Royal Air Force (RAF) between February 1943 and March 1944.

One of Frost's unique[citation needed] design touches was to fit the Hengist with a rubber bag as a landing device.

A strengthened undercarriage was used on the production aircraft and was called the Mk III, but this name was not carried over to the RAF.

[3] The Hengist had a distinctive appearance with curved upper and lower surfaces and a flat sided fuselage.
