rest of the formation, but it wouldn't be "visible" light so the
Luftwaffe wouldn't be able to find them as easily.  Eventually they
realized that the pilots who could see UV also tended to be blond,
blue-eyed, of Germanic descent....

On the other hand... UV was sometimes used for signalling between spies
and submarines off the coast. People who had had cataract operations,
with artificial lenses implanted, were chosen for coastal watch once it
was realised that the plastic they used for the lenses was much less
opaque to UV than the normal lens of the eye...
