I’m hazy on what you mean. If it’s Heinlein, I’ve read it. But that could have been a long time ago.
Our “pressure dome” is a bridge-type structure that I like to call the open space design. It has a face, two faces actually, that are also fastened together.
This allows our transparent panels (made of AlON, aluminum oxy-nitride) to be able to flip from one orientation to the adjacent one.
This kind of “tiling” lets panels move to fill in the ranks if damage occurs. We are in the Asteroid Belt, after all.
We also have crawling tractors on the inside and outside for repairs to the “track” assembly. You don’t see the ones on the inside because they’re painted a sky-blue color, and you don’t see the ones on the outside because it’s dark out there.
The repair crew are all kids, junior astronauts. Keeping the canopy in repair is training for further adventures in space.
In that short story the lunar colony kept its air in a pressurized natural dome. The pressure was such that human beings could strap on wings and (thanks to the low gravity) fly like birds.
The “Menace” was an earther who was up on tour who attracted the attention of the narrator’s best male friend whom she would never have admitted she had a yen for.
The story was a little dull but the flying idea was cool.
