A visually stunning book about all kinds of wings - not just those on aeroplanes!

A delightful story about a child & his Guardian Angel. Bright, colorful & full of fun.

When a grandmother's granddaughters discover her secret, they have many questions to ask her.

A method employed heretofore by the authors to obtain approximate solutions of the transonic flow equation for plane and axisymmetric flow is extended to give reasonable results for wings of finite span, consistent with the known properties of transonic flows. In this method the partial differential equation appropriate to the study of transonic flow is replaced by a nonlinear ordinary differential equation which can be solved by numerical methods. Asymptotic forms of this differential equation are given for very high and very low aspect ratios and analytic results are obtained for certain special cases. Numerical results, calculated by use of electronic computing machines, are given in the form of pressure distribution and pressure drag for two profile shapes, wedge and circular arc, for wings of rectangular plan form. The range of aspect ratios covered extends effectively from zero to infinity and agreement with the asymptotic results is shown at both limits.

'If Finn Maison shouts jump you jump or you are dead.' Twelve-year-old Willem has two main aims in life: to fly and to make at least two friends of his own age. But all the other boys from the Beckham Estate do is make him jump off things. First his desk - and now the wall. As his toes teeter on the edge, Sasha Bradley gives him a tiny little wink. Might she become his friend? Bullied by Finn and his gang the Beckham Estate Boyz, Willem has no choice but to jump. As he flies through the air he flaps his arms, wishing he could fly and escape into the clouds. Instead he comes crashing down and breaks his ankle. Sasha, angry with herself for not stopping Finn and his Boyz, is determined to put things right. And soon, while the gangs riot on their estate, Willem and Sasha form an unlikely friendship. Because they share a secret. Sasha longs to fly too. And when Magic Man Archie arrives with stories of war-flying spitfires, he will change the lives of the kids on the Beckham Estate for ever. And perhaps find a way for Willem and Sasha to fly ... Touching on themes such as friendship and bullying, this is a charming tale about overcoming obstacles and finding friendship in unlikely places.
