Cars and trucks entering Manhattan don't have to be on an authorized
flight plan, nor do they have to be tracked after they enter.

No, they have to be searched *before* they enter. In addition, at times, trucks
and vans are subject to random stops in the city. It's playing hell with some of
the businesses who send service techs out (like HVAC installers). The frequency
of these searches depends entirely on the security level, and Manhattan has its
own. With cars, it's more of a random deal on the bridges and in the tunnels.

Perhaps the solution to the ADIZ is to set up search stations outside of DC.
Land, get the plane checked out, get a squawk code, take off again, and go on
through. That's basically what NY is doing with trucks.
