I would like to mention that I have flown the 262 first in May ‘43. At this time, the aircraft was completely secret. I first knew of the existence of this aircraft only early in ‘42 - even in my position. This aircraft didn’t have any priority in design or production.
Tragedy is an imitation not only of a complete action, but of events inspiring fear and pity. Such an effect is best produced when the events come on us by surprise; and the effect is heightened when, at the same time, they follow as cause and effect. The tragic wonder will then be great than if they happened of themselves or by accident; for even coincidences are most striking when they have an air of design.
Flow systems have two basic features (properties). There is the current that is flowing (for example, fluid, heat, mass, or information) and the design through which it flows.
The constructive intellect [genius] produces thoughts, sentences, poems, plans, designs, systems. It is the generation of the mind, the marriage of thought with nature.
