Page 5 - I had visualised for the pistonengined scheme. In short, I was back to the gas turbine, but this time of a type which produced a propelling jet instead of driving a propeller. Once this idea had taken shape, it seemed rather odd that I had taken so long to arrive at a concept which had become very obvious and of extraordinary simplicity. My calculations satisfied me that it was far superior to any earlier proposals.
Page 33 - Industry is always looking over its shoulder at its competitors. If their research is one step ahead of their competitors they are satisfied. It has always been apparent they are not interested in the general progress of the art.

Page 318 - The men in charge of the future Air Forces should always remember that problems never have final or universal solutions, and only a constant inquisitive attitude toward science and a ceaseless and swift adaptation to new developments can maintain the security of this nation through world air supremacy.

Page 324 - And I think I speak for all of us when I say that present need is something we have no interest in getting past.

Page 11 - propulsion by the reaction of a simple jet cannot compete, in any respect, with airscrew propulsion at such flying speeds as are now in prospect.
