Other than the Wright Flyer name me an aircraft that went from drawing board to operational status without "an incident!"
No, was just tickled by the language, "which allowed the crew to validate the operation of their ejection seats.
".
Actually the Wright Flyer killed a young leutnant on his first trial hop with one of the brothers at the controls.
That may have been one of the first "pilot error" fatalities
I suppose.
