More than a century before the Wright Brothers invented their plane, brothers Joseph and ƒtienne Montgolfier sent a flying machine into the skies--a hot-air balloon with three animals in the basket. This picture book chronicles that first, magical journey! Full color.

A diabolical traitor who's always out of reach... England, 1814. Lady Arianna Hadley and her husband, the Earl of Saybrook, want nothing more than to savor a quiet life embellished by the occasional cup of the finest chocolate. However, when they receive orders to travel to Scotland and capture an elusive traitor, they feel their duty to the Crown must come first. In a laboratory in Scotland, they discover the corpse of a chemistry professor--and cryptic papers hinting at a dangerous new discovery now in enemy hands. Racing against time, Arianna and Saybrook pursue their most cunning and dangerous adversary yet through a complex network of intrigue involving exotic chocolates, daredevil aviators, a missing inventor, and a secret recipe that must be recovered at any cost... INCLUDES CHOCOLATE RECIPES AND TRIVIA! From the Paperback edition.

Modelling and Control of Mini-Flying Machines is an exposition of models developed to assist in the motion control of various types of mini-aircraft: • Planar Vertical Take-off and Landing aircraft; • helicopters; • quadrotor mini-rotorcraft; • other fixed-wing aircraft; • blimps. For each of these it propounds: • detailed models derived from Euler-Lagrange methods; • appropriate nonlinear control strategies and convergence properties; • real-time experimental comparisons of the performance of control algorithms; • review of the principal sensors, on-board electronics, real-time architecture and communications systems for mini-flying machine control, including discussion of their performance; • detailed explanation of the use of the Kalman filter to flying machine localization. To researchers and students in nonlinear control and its applications Modelling and Control of Mini-Flying Machines provides valuable insights to the application of real-time nonlinear techniques in an always challenging area.

In the 21st century - the age of the budget airline - where quick and reliable air travel is available to a large segment of society, it seems hard to comprehend that it is less than 250 years since the first human took to the skies. Although the wing of the bird seemed like the most obvious natural mechanism to attempt replicate, it was actually contained hot air, as demonstrated by the Montgolfiers and their balloon, that gave birth to the era human aviation. Since the first manned balloon flight in 1783, developments have come thick and fast, the airship, the aeroplane, and finally the space shuttle. This reprint of a classic publication by Lord Montagu, from 1907, details the early history of aviation. Complete with illustrations and a brand new introduction, and containing sections such as 'Navigable Balloons', 'A Balloon Duel', and 'A Perilous Ascent', it is a wonderful work for anyone with an interest in the technology and interesting events of the lighter-than-air period of aeronautics.
