I don't know why circling is NA at night, but for argument's sake let's say it wasn't night and you decided to try it for operational reasons, such as a longer runway with, say, a headwind component. How would you plan to avoid stalling your Learjet
then?
You might start by crossing over 27R perpendicular to the centerline. After all, why waste all that "S-turns across a road" training?
You might make sure you fly as slowly as safely possible, too, such as Vref+10 (1.3 Vso for the weight + 10 kias) because you don't want to waste all your slow flight training either, do you?
You might also make sure to use full flaps, so you don't stall while trying to fly at Vref+10 kias. This is no place to test your stall training, of course, but it might fly in the face of conventional wisdom learned in simulator training, where approach flaps may have been drilled into your head for fear of an engine failure. But, as risk manager, you must decide which is the more important consideration.
And you won't bank even one degree over 30°, no matter what, for the same reason. (No place to test your stall recovery proficiency.)
And you would make sure to avoid the obstructions by maintaining circling minimums until a "normal descent" can be made visually. With such a high circling minimum as at SEE,
IF this were an unfamiliar airport and/or
if it were a night approach, the only safe way to mitigate the obstruction risk would be to hold those minimums until within 10° of final approach. That could be a deal-breaker if it requires a longer final than the protected circling area.
Above all, though, you'd have to be super alert for the first indication of any of your parameters straying from perfection, in which case you'd simply execute a missed approach.
If this approach was an ad hoc decision to circle, made out of an approach gone poorly by arriving too high and too fast, I'd suspect the crew didn't have time to consider all of these things. It's the sort of 91.103 alternative planning required before takeoff, if such a maneuver is to be accomplished safely that is.
