Travels of an amateur engineer: Fantastic technical sights in the United States, the United Kingdom, Germany, France - and more.

Australian Julian Edgar decided he wanted to see the best technical sights the world has to offer. To achieve this, he and his wife and young son spent nearly five months travelling internationally. In Germany, the United Kingdom, France, Sweden and the United States, they've gone to the best technical museums, seen the best car museums and been to the best aviation museums. They've seen Detroit's crumbled industrial heart, been stunned by the awesome Firth of Forth bridge, and been inside the industrial horror of Dachau concentration camp. From being underground in a Cold War nuclear bunker, to seeing the code-breaking machines that shortened World War II. From the Nazi WWII rocket range at Peenemunde, to the biggest and best model railway layout that exists. Along the way, they've also seen the world's fastest aircraft, helicopter, steam locomotive and car. This diary covers those travels, identifying more than 100 must-see sites for tech-heads. With nearly 400 full-colour photos, this is a visual and descriptive feast. The perfect book for the armchair traveller - or for someone who wants to undertake similar travels themselves.
