Three article-length monographs reveal fascinating insights into some of the greatest highways and least-known byways of aviation throughout its history. Comprehensively illustrated with many rare and unique images.

The Levis-Belmont Affair: Back in the pioneer era, the Levis motorcycle company and Belmont aeroplane company teamed up to create a series of experimental aeroplanes. A unique five-cylinder inline two-stroke aero engine survives on display in the Science Museum. But what about the aeroplanes?

Essex Aero: During the Golden Age of Aviation, de Havilland's racing Gipsy Six R engine took the laurels in both the de Havilland Comet racer and the Percival Mew Gull. But what of Essex Aero, the technological powerhouse behind those stories? From Spitfire fuel tanks to the stunning S-X Magbody Allard classic roadster, Essex Aero are full of forgotten surprises.

The F-18 Hornets that Aren't: The Swiss Air Force today operates the F/A-18C Hornisse air superiority fighter from their mountain bases. Except, two of those warplanes are not real aircraft; they are world-leading training simulators made by Hugo Wolf AG. Their story is told here in English for the first time.
