It is a valuable source to learn about activities done by Sir Frank Whittle. With the development of the jet engine he had significantly contributed to the success of RAF over the Luftwaffe during the WWII. If we want to correctly evaluate the significance of the jet engine in the flight history, we do not forget to mention another pioneer, Hans von Ohain, who has successfully developed his engine at the same time as Whittle did. It is worth comparing their works and success.
