Something In The Air

The following was inspired by a true question posed to the Beis Shlomo.
Boruch went to the daf yomi shiur and learned Zevachim 87b. The Gemara questions whether the airspace above the Mizbeiach has the same sanctity as the Mizbeiach itself. The Gemara attempts to find proofs to both sides of this question, but they were ultimately rejected. Seemingly, this question remained unresolved.
Boruch was speaking with Reuven, a member of his shul, who tends to disagree with him on most issues.
Boruch: The daf really got me thinking about airspace. Our shul really needs office space. The ceilings in the main sanctuary are 20 feet high. Let’s make the back of the shul only 10 feet high and build a floor over the back part of the shul and use that for office space.
Reuven: Do you really have that much disregard for the sanctity of the shul? You will be turning sacred airspace into office space. I think the following Latin phrase is apropos: Cujus est solum, ejus est usque ad coelum et ad inferos — literally, “To whomsoever the soil belongs, he owns also to the sky and to the depths.” When someone owns land, he owns the air rights up to the sky. The shul’s sanctity likewise extends skyward, and you cannot build an office in any of the 20 feet of airspace already designated as a shul.
