1. how far away do controllers "notice" planes that are entering the
ADIZ? (how many minutes away is a threatening 152)

Controllers aren't tasked with noticing or caring. There are other
people watching the radar (and different RADAR than the one ATC is using
in some cases).

But the answer is that they know right when you clip the edge. There
have been a few intercepts for people who almost busted the ADIZ (we
have a word for almost busted around here, it's called Remaining Clear).


3. Did the fighters or blackhawk intercept the plane before or after the
threat was gone?

The DC111 at ADW is ready in 15 minutes, so if he's heading straight
downtown you do the math. The blackhawks are probably more pracical
(they can fly at 150 speeds).
