since the spacecraft is traveling at c already none of
the observers can "see" any light with their eyes except
any observers that are traveling with the spacecraft
at c and close to c

thats why I used detection equipment ... our eyes could not
see light that is outside of the wavelenghts of the
visible light spectrum.

and if you add c to any wavelenght in the visible light
spetrum that wavelenght drops out of the visible light
spectrum.
