If we were to mark on a map a typical trajectory of a landing Shuttle, and then mark on the same map the swath either side of that trajectory within which domestic flights were forbidden within a certain timeframe during which the Shuttle was landing ...

... how wide would that swath be?

And the mentioned 'timeframe': during what sort of time-window around the landing of a shuttle would domestic flights be forbidden from that swath?

I've actually tried to find a map literally as I've described, with said features marked on it ... but I haven't been able to.

Basically I would presume that anyone wishing to take a flight crossing the Southern border of USA during the time-window starting @least an hour or so before planned descent & lasting until descent was successfully completed would just have to wait !
