. From the early 1930s to around 1970 it built over 50% of all British club gliders and had success at national and international level competitions.
It then produced some powered aircraft, notably the composite built
Firefly trainer, before becoming a producer of specialised composite materials and components.
The business is now known as Marshall Advanced Composites and produces composite parts for ships, submarines and aircraft. It is a subsidiary of

History

The business was founded in
Scarborough by
Frederick Nicholas Slingsby, an
RAF pilot in World War I. In 1920 he bought a partnership in a woodworking and furniture factory in Queen Street, Scarborough. In 1930 Slingsby was one of the founders of the

. After repairing some of the club's gliders, Slingsby's business built its first aircraft, a German designed
RRG Falke which flew in 1931. By late 1933 Slingsby was advertising training gliders for sale. In 1934, encouraged by a local landowner, the business moved to Kirkbymoorside, some 30 miles from Scarborough, operating as Slingsby, Russell & Brown Ltd. As demand for gliders built up, a new factory was needed and built in
Welburn, just outside Kirkbymoorside. This opened in July 1939, when Slingsby Sailplanes Ltd was founded.
The best selling Slingsby glider in the pre-World War II period was the
