Doing Stunts?
I like to think about experimentation and I'm a fan of Mr. Eddington.
In ancient days two aviators procured to themselves wings. Daedalus flew safely through the middle air and was duly honored on his landing. Icarus soared upwards to the sun till the wax was melted which bound his wings and his flight ended in fiasco.
The classical authorities tell us, of course, that he was only "doing a stunt", but I prefer to think of him as the man who brought to light a serious constructional defect in the flying-machines of his day.
Sir Arthur Eddington
