and he notes -
Thanks for the English lesson. However I have had experience in
"opaquing" windows (to coin a term) and as a former newspaper editor,
I believe I have a grasp of the English language. I majored in the
subject in college and planned to be a teacher but went on to a more
lucrative technical career in aerospace and electronics.
Incidentally, during WW II Union Station in Chicago had its skylights
over the train shed painted black to thwart enemy bombers (which
never came) using it as a beacon. They were obviously opaque. They
were still painted black when I lived there back in the 90s but I
seem to recall reading somewhere that they have since been restored
to their former translucent glory.
Raleigh in Maine - always humble but ever critical, looking at the
glorious sun through my translucent drapes...;-)
