No, of course not. The glass ceiling is, obviously, a metaphor for a real ceiling.
Not to go off-topic, but...
Where I'm from, "a real ceiling" often means a ceiling made of glass.
So it seems like you're saying, "the glass ceiling is, obviously, a metaphor for a ceiling made of glass." You might want to make your statements less cryptic in the future.
Of course I should have been more explicit, but as GM-chihorn and I were merely talking shop as subject matter experts in the human cannon field, there's a basic assumption of industry standards inherent in our postings that aren't necessarily apparent to the onlooker.
In any case, in this matter, at the present time none of the human cannons licensed for use in the USA are rated for use in breaking through ceilings made of glass. Inside the business, "real ceiling" is actually very narrowly defined to the various ceiling parameters that are approved as human cannonball "receptacles", though there's no need to get into the minutiae at this point in time. Had I been a thoughtful poster, I would have been sure to replace "real ceiling" with "subsection 15b compliant real ceiling, as determined by a structural review by licensed building integrity evaluators as defined in subsection 12a".
(I suppose a simpler response of: "Really,
that's the part of this you have a problem with?" would have been sufficient, but where's the fun in that?)
