Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Only one who follows events attentively from day to day can now realise the extraordinary rapid strides which aviation is making. This book - and notably such features of it as the list of the world 's airmen and the records of the chief flights made - may, we hope, bear testimony to the astonishing growth of flying, and particularly to the energy and enthusiasm of those engaged in its development.
