Interesting book. the author Nevil Shute was an engineer involved in the building of the R100/R101 and the establishment of the Airspeed aircraft building company. Concentrates on the interval between the two world wars, when he was a young man, working his way in aircraft design. Was recomended to me as good reading for how a small company grows and the growing pains it has to endure. It was actually quite illuminating in that regard.
