Yeah. The logical point to mention hot air balloons was in the early passages of AtSoT when the Inner Circle was discussing them and Green Valley was ruminating on them. You know, in the snippets that were dropped for us prior to the whole book being released.
It's pretty well established procedure by this point to explain how new innovations don't violate the Proscriptions by pointing to all the pre-existing precursor technologies that make the innovation possible at all.
The early balloon passages?
They didn't do that. They just dropped "Charis has balloons now!" and didn't explain why they didn't violate the Proscriptions until they were unveiled for the other side to see.
Edit: On the flip side, I can see why Weber didn't want to waste word count on explaining something the Church side was going to explain anyway.
But still, this is the kind of innovation that he had to have planned from the very beginning. So he SHOULD have included mention of hot air balloons even in passing in one of the earlier books. Possibly even in the very FIRST book.
