Rolls Royce turbine blade: These are some of the most hi-tech items ever made. They are located inside the hottest part of a jet engine, and in an environment that gets hotter than the melting point of the material they are made of. Based on ancient techniques of lost-wax investment casting, the blades are cast and set to form a single crystal. Only this is strong enough to survive. Tiny tubes are cast into the blades, and air is blown through them to form an air cushion around the blade, so that they don’t melt. The blades are testament to the ability of engineering design to overcome monumental obstacles.

Ronan Point: In 1968 an exploding cooker at Ronan Point in Newham causes the entire corner of a towerblock to collapse, killing four and injuring 17. The collapse was due to a weakness in the precast panel system used to build it, where the loss of one panel caused the progressive collapse of other floors. What is inspiring is that the engineering profession examined and understood the failure and then changed building regulations and design approaches to ensure it could not happen again. Learning from failure is incredibly important.

A new house in rural Philippines: After the devastating Typhoon Haiyan in 2013, CARE provided technical support, cash and materials to over 16,000 households, so they could rebuild their houses. This woman has designed and built this house herself, incorporating bracing, joint reinforcement and other measures suggested by CARE to strengthen the structure. It serves as a reminder that if we could just make good, basic engineering available to all the world would be a better, more resilient, more just place.

Mobile phone mast: Ugly and undesirable? Or a revolution in communications. Mobile communications has revolutionised how people interact and communicate, but nowhere more so than in poorer countries, where mobile telephones have allowed new economies to develop with mobile money and payments and the spreading of information and knowledge. It costs very little to roll out and maintain a network of masts; now everyone can be connected.

The Northern Outfall Sewer: in East London a path called the Greenway runs alongside the Olympic Stadium. Underneath it lies the Northern Outfall Sewer. Designed by Joseph Bazalgette after the 1853 cholera outbreak it was the first major urban sewer system in the world, and is still the basis of sewer design today. Modern sewerage has saved millions of lives.

Readers Digest Atlas of the British Isles. Pre-internet this book laid out the way the country works how industry, transport, people , nature all interact to make a nation. It kept me occupied on wet winter days and was in introduction to the way we better understand complex things by drawing them out together.

Clive Irving, “Wide Body, The making of the 747”.An amazing leap in technology in 1966 that nearly bankrupted Boeing. It went into service in 1970 and 46 years later is still the most used aircraft in the world. I recently heard that Joe Sutter below is still alive and occasionally comes into the office provided there are no finance guys present.

First to Fly – James Tobin John Murray 2003 Tells the story of the Wright Brothers development of powered flight. Around the year 1900 there was a number of people around the world grappling with the task of powered flight. In America there was Samuel Langley, a prominent scientist and head of the Smithsonian Institute who was running a well funded programme in Washington and the Wright Brothers from Dayton, Ohio who ran a cycle building shop. The Wright brothers were self-funded and self-taught. They built a small wind tunnel to measure the lift and drag of wing sections. Patiently they tried out ideas for gliders, developed a suitable engine and propellers. The key to their success was that they realised that they had to have control of the craft about three axes, lift, yaw and roll. The last they dealt with by wing-warping which on their light flexible biplane could be achieved by pulling on wires. By the time they flew their craft around the Statue of Liberty they realised that wing warping was not going to be the future of flying and while their achievement was recognised but their later life was troubled with vexatious law suits.
