Sailplanes 1920 bis 1945 - Eqip, Königswinter, 2001.
This book, Volume 1 of a projected series, describes and illustrates more than 120 types of sailplane,
designed, built and flown in many countries during the quarter century following the first organized gliding competition
on the Wasserkuppe in 1920.
The astonishing achievements of designers and builders, lacking modern materials and production methods,
and the flights made by the pilots of those times, deserve to be recorded and remembered.

This, the second volume of 'Sailplanes' by Martin Simons, describes the extraordinary transformation in soaring that took
place from 1945 to 1965. To take advantage of discoveries in low drag aerodynamics it became necessary to develop new
structures and methods of construction. Almost every possible combination of materials and techniques was tried with
varying success. A great variety of sailplane types appeared. Towards the end of the period, glass-reinforced plastics
were achieving great advances in performance.

The third of the series, 'Sailplanes' brings the story up to the end of the 20th Century.
Plastic structures became orthodox. Glass was supplemented with carbon and aramid (Kevlar) fibers as reinforcing materials.
The improved strength and accuracy of structures allow advantage to be taken of new wing profiles.
Retracting motors became more acceptable.
